Arduino Nano Meduino Enchancement (3.3/5V adjustable)16MHz MEGA328

Meduino Nano Enchancement (Arduino-Compatible)(3.3/5V adjustable)16MHz MEGA328 This board is completely compatible with arduino nano. But also has the enhancement features. Such as the power supply. Besides 5V, the board can also work under voltage, just use the switch to change between and 5V. This makes the board easy to communicate with most of the sensors(works under ). Features: 1. VIN:6V-12V power input. 2. VCC(Working voltage): 3. Maximum 800mA output. 4. Pin pitch: 0.1 inc
