Neoprogrammer 21019 Ch341a Hot

Trace the 5V line from the USB port to the 5-pin or 3-pin chip nearest to the USB connector. That is your power regulator. That is the component generating the heat. Replace it, and verify your 3.3V output is exactly 3.3V before plugging in a BIOS chip.

If the programmer gets hot even when no chip is connected, an on-board component may have already failed:

The combination of and the CH341A USB programmer represents one of the most popular, cost-effective methods for flashing BIOS chips, EEPROMs, and SPI Flash memory. However, users frequently encounter a alarming symptom where either the CH341A programmer dongle or the targeted IC chip becomes physically hot during operation. This article provides a comprehensive guide to understanding this phenomenon, configuring the software, and safeguarding your hardware.
