OSOYOO 3pcs Nano Atmega328P Module CH340 5V/16M USB-C Micro-Controller Board for Arduino Nano V3.0

Microcontroller ATmega328P–8 bit AVR family microcontroller. CH340 USB Chip The CH340 chip on the Nano is only powered if the board is being powered over USB. Memory The ATmega328 has 32 KB, (also with 2 KB used for the bootloader. The ATmega328 has 2 KB of SRAM and 1 KB of EEPROM. Classic LED Project with Nano Board This example project shows the simplest thing you can do with an Nano to see physical output: it blinks the on-board LED just like the star in the sky. Input and Output Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. Some pins have specialized functions: Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the CH340C USB chip. Easy using-with USB-C cable To provide excellent service for customers Power The Arduino Nano can be powered via the USB-C connection, 6-12V 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.
