The CH341A chip is a USB interface chip that handles data transfer. It is not uncommon for these chips to run warm, especially when powering a target chip (the EEPROM/BIOS chip) directly from the USB port.
: Most chips must be blank before writing new data. Use the Erase IC function . neoprogrammer 21019 ch341a hot
The software includes diagrams for necessary adapters (e.g., for 1.8V chips or specific MCUs) directly in the interface. Stability: The CH341A chip is a USB interface chip
If your device is running "hot," the issue is almost certainly in the section. These programmers are often designed to run on 5V, but many cheap CH341A modules use a Low Dropout Regulator (LDO) like the RT9193-3.3V or an AMS1117-3.3V . neoprogrammer 21019 ch341a hot
But with caveats.
