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 equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.

The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano R3). It has more or less the same functionality as the Arduino Uno but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.

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.
If you are getting the error while uploading the code in the Arduino Nano or not detecting the port need to upload the bootloader.


  1. 1 pair of TTL level serial transceiver ports RX / TX
  2. Using Atmel Atmega328P-AU MCU
  3. There is a bootloader installed in it
  4. Support USB download and Power
  5. Support for external 5V ~ 12V DC power supply
  6. Support power supply by 9V battery
  7. Support ISP download
  8. Automatic reset during program download.
  9. Power OK blue LED on the bottom.
  10. Green (TX), red (RX), and orange (L) LED.
  11. +5V to AREF jumper.
  12. Auto-sensing/switching power input.
  13. Small mini-B USB for programming and serial monitor (cable not included).
  14. ICSP header for direct program download.
  15. Standard 0.1” spacing DIP (breadboard friendly).
  16. Manual reset switch.

    I ordered one in 2019, it worked nicely for my project.


  3. auroleoshmandal (verified owner)

    Works as expected…. Would recommend to buy the breakout board as the pins are kind of hard to push down on the breadboard without damaging it… Product works like a charm though


  4. joe (verified owner)

    works nicely, well packed, great value for money!!


  5. ansmandar (verified owner)

    Good Product and working perfectly.
    The only problem I found with the connector pins are not so clear and I had to clean each and every one of them and took me lot of time.
    It was having some resistance and causing voltage drop across the pins, because I think it was kept in store room for long time. After cleaning them it works fine.

    Set as UNO in Arduino IDE (settings as nano didn’t work). Working great. Arrived in a good package.


  7. Abhijit (verified owner)

    Works Great. Highly satisfied and the the product was delivered on time



    Use settings for UNO(not nano) while uploading ino scripts from IDE. Good quality one..its a UNO squeezed in to a nano great..

    I have been using this product everyday since 12th Oct and the usage is more than 4 hours a day. It is performing very well without any issues. Have interfaced it with IR Remote, LCD Display and DC Motor through L293 Motor driver. Everything works perfectly. The small footprint of this board comes in very handy to develop your own hardware applications.

    The soldered board option is just so good. Saved a lot of time for me. Good product. The board i received first did not work, but their quick response ensured i got a replacement within a week!


  25. Abhijit Majee (verified owner)

    This product is as good as I expected. The important point here Is the want to make is that you can purchase this soldered Arduino by just 10-15 more bucks than the unsoldered one. This not only saves time and effort in soldering the quite small pins but it also gives us a ready-to-go product to be used in our projects. I have bought both and seen the diff myself.
