Battery holder 2x 18650 3,7V Parallel Lithium Battery

Laminated Copper Clad Prototype PCB Circuit Board 30x19cm.

Imagine the simplicity of the Arduino One connected to the communication module. Seems too good to be true, right? That's Arduino One WiFi. Arduino Uno WiFi REV2 (ABX00021) with its integrated IMU (Inertial Measurement Unit) and WiFi is the ideal board to start making your first Internet application from scratch, or to use in the educational field. It has 14 digital input / output pins (5 of which are PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, an accelerometer, an RGB LED, a power connector and an ICSP header.
