Get ready to face the most versatile portable and Esp32-based development board of the moment It is 100% Arduino compatible and it is lightweight and invisible to carry thanks to its uniquely thin PCB with 8 X sewable pads. Moreover, it will not sting you because the PCB design has no sharp edges. In addition, four of the pads are capacitive touch-activated. As for the versatility, this small development board of 56 X 50 X 7.5 Mm (2.2 X 1.97 X 2.95 inches) has many features such as a Hall Effect sensor, a temperature sensor, and an ultra-low power analog preamp. But the nicest feature on board is undoubtedly the ability to connect the card to Wifi and Bluetooth®. Get any ideas? Here's one: Connect the board with our collection of Birghtdot wearable LEDs and make them react to text or social messages, magnets, sounds, time, temperature, and more You can easily connect this wearable with a battery thanks to the Jst connector and you don't have to worry about high power consumption because the board also has a deep sleep mode to keep consumption to a minimum when you don't need it. To top it all off, this thin board is at least 10 times faster than an Arduino Uno due to its super-high 240 Mhz clock.
