4PCS for Nano ATmega328P Board 5V 16M Type C Controller Microcontroller Board, Compatible with Arduino Electronics Development 328P

The Nano can be powered via the type c connection, 7-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. The nano has 8 analog inputs,each of which provide 10 bits of resolution.By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference function. Analog pins 6 and 7 cannot be used as digital pins. Additionally, some pins have specialized functionality It is a smallest, complete and breadboard friendly board. It has everything that Arduino/Genuino UNO has (electrically) with more analog input pins and on board +5V AREF jumper. This board is using the chips ATmega328P and CH340G, not FT232 as official Arduino. More Breadboard Space:Nano's got the breadboard-ability of the Boarduino and the Mini USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND ）on one top, power and ground on the other.
