TISEKER Mini Nano V30 ATmega328P Microcontroller Board with USB Cable for Arduino

The Nano for arduino can be powered via the MiniB USB connection 620V 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 inputseach of which provide 10 bits of resolutionBy 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 some pins have specialized functionality Small Arduino UNO BoardIt is a smallest complete and breadboard friendly board It has everything that ArduinoGenuino UNO has electrically with more analog input pins and onboard 5V AREF jumperMore Breadboard SpaceNanos got the breadboardability of the Boarduino and the MiniUSB with smaller footprint than either so users have more breadboard space Its 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 SpecificationThe Nano can be powered via the MiniB USB connection 712V unregulated external power supply pin 30 or 5V regulated external power supply pin 27 The power source is automatically selected to the highest voltage sourceUsage The Nano is 100 compatible with Arduino with the same chips ATmega328P and CH340 with the official version.
