Nano CH340 Chip Board Compatible with Arduino
The CH340 Soldered Nano Board R3 Chip without USB Cable is a compact variant of the popular Arduino platform, delivering all the functionality of the Uno but in a smaller package.
This Nano board is essential for small projects where minimizing size is crucial, while still offering a practical number of pin-outs.
Featuring a cost-effective USB-Serial Chip, it’s more affordable than earlier Nano versions that utilized the FTDI USB-Serial Chip.
The Nano is a compact, breadboard-friendly board based on the ATmega328 (Arduino Nano R3). It retains the core features of the Arduino Uno but in a different format, lacking only a DC power jack and using a Mini-B USB cable instead of a standard one.
Power options for the Nano include a mini-USB connection, a 6-20V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27), with the system automatically selecting the highest voltage source.
Measuring just 43 mm x 18 mm, the Nano V3.0 with the CH340 Chip includes 6 PWM I/O from a total of 14 digital I/O, 8 analog inputs, a 16 MHz clock speed, and 32 kB of flash memory.
Features
- 1 pair of TTL level serial transceiver ports RX / TX
- Using Atmel Atmega328P-AU MCU
- There is a bootloader installed in it
- Support USB download and Power
- Support for external 5V ~ 12V DC power supply
- Support power supply by 9V battery
- Support ISP download
- Automatic reset during program download.
- Power OK blue LED on the bottom.
- Green (TX), red (RX) and orange (L) LED.
- Auto sensing/switching power input.
- Small mini-B USB for programming and serial monitor.
- ICSP header for direct program download.
- Standard 0.1” spacing DIP (breadboard friendly).
- Manual reset switch.
Note: – CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.
