WiThumb is an Arduino compatible USB powered WiFi IoT development board with 6 DOF IMU, precision temperature sensor and optional plastic case.
With WiThumb, adding WiFi, temperature sensor, Gyroscope and Accelerometer to your IoT project is a breeze. In addition, optional plastic case not only protects the circuits but also adds professional look to it. Why bother messy wiring or ugly project boxes while you can get this elegantly dressed up WiThumb.
In addition, WiThumb could be powered by standard USB type-A ports found in many power adapters, computers, TV, routers, cars, solar chargers and etc. It makes WiThumb an ideal device to deploy your applications anywhere.
