Description:
This compact Nano R3 board, based on the Arduino platform and featuring the CH340 chip, offers the functionality of an Uno in a smaller form factor. Ideal for space-constrained projects, it uses a cost-effective Mini-USB connection and ATmega328 microcontroller. This breadboard-friendly board is a budget-friendly alternative to the FTDI-equipped Nano.
The Nano board accepts a wide range of power inputs: 5V via Mini-USB or regulated supply, and 6-20V unregulated. Automatic voltage selection ensures stable operation from the highest available source.
The compact Nano V3.0 (CH340) measures just 43x18mm, offering 14 digital I/O (6 PWM), 8 analog inputs, 16MHz clock speed, and 32kB flash memory.
