The CH340 Soldered Nano Board R3 Chip without USB Cable chipboard is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint.

Nano CH340 Soldered Board R3 Chip without USB cable is vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good.

The Nano can be powered via the mini-USB connection, 6-20V 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.

The size of Nano V3.0 with CH340 chip is only 43 mm x 18 mm; it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory.

Note:- CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.
