4Pcs for Nano V3.0 ATmega328P Nano Board CH340 5V 16M Micro USB Microcontroller Board with PIN Headers Pin Unsoldered Compatible with Electronics Development Board Nano 328P Nano 3.0

4pcs Arduino Nano V3.0 ATmega328P 16MHz Micro USB Board CH340 Driver The Nano motherboard can be powered through the Mini-B USB port, an unregulated 6-20V external supply (pin 30), or a regulated 5V external supply (pin 27). The system automatically selects the power source with the highest available voltage. This board features 8 analog input pins, each offering 10-bit resolution. By default, they measure from ground to 5 volts, but the upper range limit can be adjusted using the analogReference function. Note that analog pins 6 and 7 cannot function as digital pins, and certain pins have dedicated specialized functions. It is the most compact, fully-featured, and breadboard-compatible board available. It provides all the electrical capabilities of the standard board, with additional analog input pins and an on-board +5V AREF jumper. It is compatible with Windows, Mac, and Linux operating systems. The Nano's design maximizes breadboard space: it offers the same convenient breadboard compatibility as the Mini USB version but with a smaller footprint, freeing up more area on the breadboard. Its pin layout is optimized, grouping communication pins (TX, RX, ATN, GND) on one end and power and ground pins on the other for easy integration with devices like the Mini or Basic Stamp. This board is equipped with the ATmega328P and CH340 chips (not the FT232). It supports ISP download, USB download, and power functions. Ram Memory Installed Size: 2 KB
