This ESP32-based wearable development board is 100% Arduino compatible and easy to wear thanks to its ultra-thin PCB with 8 sewable pads, 4 of which are capacitive touch-enabled. The PCB has no sharp edges and measures 56 x 50 x 7.5 mm.
On board you get WiFi and Bluetooth, a hall effect sensor, a temperature sensor and an ultra-low power analog pre-amplifier. A JST connector and integrated LiPo charger make battery power easy, and deep sleep mode keeps consumption to a minimum when the board is idle. With its 240 MHz clock, the board is at least 10 times faster than an Arduino Uno. It is compatible with all BrightDot wearable LED boards.
