FTDI Basic Breakout - 5V
Click here for specs and more pictures.
Description: This is the newest revision of the FTDI Basic. We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same.

This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.

This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.

One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.

EasyDriver Stepper Motor Driver
Click here for specs, downloads, and more pictures.
Description: The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment.

This is the newest version of EasyDriver V4 co-designed with Brian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.

Caution: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.

Triple Axis Accelerometer Breakout - ADXL345
Click here for specs, downloads, and more pictures.
Description: This new version adds 2 standoff holes as well as an extra decoupling capacitor. The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. 
The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°.

Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

Features:
  • 2.0-3.6VDC Supply Voltage
  • Ultra Low Power: 40uA in measurement mode, 0.1uA in standby@ 2.5V
  • Tap/Double Tap Detection
  • Free-Fall Detection
  • SPI and I2C interfaces

Triple-Axis Digital-Output Gyro ITG-3200 Breakout
tn_09801-01.jpg
Description: This is a breakout board for InvenSense's ITG-3200, a groundbreaking triple-axis, digital output gyroscope. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface. Additional features include an embedded temperature sensor and a 2% accurate internal oscillator.
The ITG-3200 can be powered at anywhere between 2.1 and 3.6V. For power supply flexibility, the ITG-3200 has a separate VLOGIC reference pin (labeled VIO), in addition to its analog supply pin (VDD) which sets the logic levels of its serial interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD max. For general use, VLOGIC can be tied to VCC. The normal operating current of the sensor is just 6.5mA.

Communication with the ITG-3200 is achieved over a two-wire (I2C) interface. The sensor also features a interrupt output, and an optional clock input. A jumper on the top of the board allows you to easily select the I2C address, by pulling the AD0 pin to either VCC or GND; the board is shipped with this jumper tied to VCC. If you don't plan on using the CLKIN pin, you can short the jumper on the bottom of the board to tie it to GND.

This breakout board is shipped as shown in the images. Note that there are two unpopulated resistors on the I2C lines, these can be added later by the customer if desired.

Features:
  • Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
  • Digitally-programmable low-pass filter
  • Low 6.5mA operating current consumption for long battery life
  • Wide VDD supply voltage range of 2.1V to 3.6V

Analog/Digital MUX Breakout
Click here for specs, downloads, and more pictures.
Description:This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip can be used to connect 16 analog sources (like sensors) to 5 pins on a microcontroller. 4 of the pins must be digital pins, 1 pin must be an analog to digital conversion pin. This allows 16 sensors to operate on only 5 pins of a micro! This is a great way to connect a lot of sensors to a few pins.

You can also run the mux/demux the other direction. One serial stream connected to the SIG pin can be piped to multiple outputs.

The mux/demux also works with digital signals (like serial, I2C, SPI). This means you can hook up multiple serial devices (like a GPS TX pin, and a XBee DOUT pin) to one RX pin on a microcontroller.

The IC can control analog voltages that vary across the voltage supply range. The bidirectional switches allow any analog or digital input to be used as an output and vice-versa with a "Break-Before-Make" switching of 6ns at 4.5V. In addition, the switches have low "on" resistances and low "off" leakages. Includes and enable control which when high will disable all switches to their "off" state.

Features:
  • ON Resistance 70Ohms @ 4.5Vcc and 60Ohms @ 6VCC
  • 2V to 6V operation
  • Wide operating temperature -55C to 125C

Humidity Sensor - HIH-4030 Breakout
Click here for specs, downloads, and more pictures.
Description: This is a breakout board for Honeywell's HIH-4030 humidity sensor. The HIH-4030 measures relative humidity (%RH) and delivers it as an analog output voltage. You can connect the output of the sensor directly to an ADC on a microcontroller; and, thanks to the sensor's near linear voltage output, the data is very easy to process.
Voltage applied to the supply pins should be within 4-5.8VDC, and optimally at 5V. The sensor will typically only consume about 200μA.

This product comes as shown in the picture, with the HIH-4030 soldered onto the breakout board. The pins of the 3-pin header are spaced by 0.1".

Features:
  • Near linear, analog output
  • 4-5.8VDC voltage supply
  • All pins broken out to a 0.1" pitch header
  • Laser trimmed interchangeability
  • Low power design, typical current draw of only 200μA
  • Enhanced accuracy
  • Fast response time
  • Stable, low drift performance

Serial Enabled 16x2 LCD - Black on Green 5V
Click here for specs, downloads, and more pictures.
Description: This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector.

SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast.

This LCD makes for a great gift, because it can be used for so many different projects!

Features:
  • Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy
  • Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400
  • Operational Backspace
  • Greater processing speed at 10MHz
  • Incoming buffer stores up to 80 characters
  • Backlight transistor can handle up to 1A
  • Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
  • All surface mount design allows a backpack that is half the size of the original
  • Faster boot-up time
  • Boot-up display can be turned on/off via firmware
  • User definable splash screen
Dimensions:
  • PCB: 103x36mm
