The Keyestudio NANO PLUS Development Board features the ATMEGA328PB-AU processor core, identical to the official Arduino Nano but enhanced with a CH340C USB-to-serial chip and driver. It includes 14 digital I/O pins (6 PWM-capable), 8 analog inputs, a 16 MHz crystal oscillator, an ICSP interface for programming, and a reset button. Power can be supplied via a USB Type-C cable or through VIN/GND ports (DC 7-12V), offering versatile and reliable option for embedded applications.
