The Neoprogrammer 21019 CH341A Hot: A Comprehensive Review and Guide

Note: If you aren't comfortable soldering, consider buying a "Green" version or a newer revision that has already fixed this flaw. 3. Use a 1.8V Adapter

• Disconnect main power (battery, PSU).
• Identify the flash chip (e.g., Winbond 25Q64FVSIG).
• Hold the board’s CPU in reset – short the RESET pin to GND or pull the reset line low. This tri-states the CPU’s SPI pins.
• Alternatively, remove any jumpers that enable boot flash.

• Attach the SOIC clip to the flash chip. Double-check pin 1 orientation.
• Connect clip wires to CH341A:

  If your chip is oriented correctly but still gets hot, you may need to modify your programmer. Users often solder a jumper wire between Pin 28 of the CH341A chip and the 3.3V regulator to ensure the data lines stay at a safe voltage. neoprogrammer 21019 ch341a hot
