Introduction
The processor core of Keyestudio Nano CH340 is atmega328p-au. It is as same as the Arduino Nano in addition to driver file and USB to serial chip (CH340G). It also has a 14 digital input / output interfaces (6 of which can be used as PWM output), 8 analog input interfaces, 1 16MHz crystal oscillator, 1 mini USB port, 1 ICSP interface, and a reset button.
The ICSP interface is used to burn firmware to Atmega328P-Au. Since this chip we burn firmly in front of the factory, it is generally not available. When using the Mini USB cable, we can use the VIN GND (DC 7-12V) to power.
What's more, you can burn the firmware for Atmega328P-Au through the built-in ICSP port. The firmware of this chip is burnt well before delivery, therefore, you don't need to burn the firmware.
The power can be supplied through USB cable, port 5V , GND(DC 5V), as well as Vin GND (DC 7-12V).
