| Risk | Cause | Mitigation | |------|-------|-------------| | Damaging motherboard | CH341A’s 5V on 3.3V rail | Measure VCC pin output; use 3.3V mod (cut 5V-3.3V jumper, add external regulator) | | Chip misdetection | Other SPI devices not deselected | Use “CS” (chip select) isolation; or unsolder resistor to VCC on target board | | Data corruption | Loose clip connection | Use a SOIC8 clip with spring-loaded pins; slow SPI speed in software (lower to 1 MHz) | | Overheating CH341A | Continuous write >5 minutes | Add heatsink to CH341A IC, pause between operations |
NeoProgrammer 2.1.0.19 is a popular alternative software used for the CH341A USB programmer
