CH341A Readable And Writable USB Programmer + SOP8 Burner Clip + SOP8 Adapter + 1.8V Adapter

Product Characteristics

CH341A USB Universal Flash Programming Toolkit

A universal and cost-effective solution for reading, writing, erasing and repairing firmware on 24/25 series SPI Flash (EEPROM) chips. Designed specifically for enthusiasts, maintenance technicians and electronics lovers, this kit supports circuit programming through non-destructive test clips, eliminating the need for desolder-removing. Powered by the CH341A USB interface chip, it provides reliable firmware repair tasks compatible with consumer electronics, including BIOS/UEFI recovery, router modification, and TV/set-top box repair.

Data management: Back up, erase or modify the firmware on routers, TVS, set-top boxes and car ECUs.

Hobby Project: Custom Flash firmware for Internet of Things devices, vintage game consoles or Arduino-compatible boards.

Safety: Safely erase sensitive data from discarded electronic devices.

Product Advantages

Beginner Friendly: No welding required; The test clip can realize circuit programming.

Wide Compatibility: Supports thousands of 24/25 series chips and common 3.3V/1.8V SPI Flash.

Portable And Affordable: The compact design is ideal for field work or home laboratories.

Explanation

Driver Installation: Required for Windows (Download from the manufacturer's website)

Test the stability of the clamp: Ensure that the chip pins are correctly aligned to avoid read/write errors

Voltage Check: Please verify the chip voltage (1.8V or 3.3V) before programming.

Precautions

BIOS chip connection method and chip pin diagram: Since the BIOS chip of a tablet is not directly plugged and unplugged like that of a desktop computer, when connecting the BIOS chip with the SOP8 test clamp, it is essential to pay attention to the corresponding pins. If the pins are connected in the wrong direction and the chip is burned out, it will be counterproductive. Pin 1 of the BIOS chip of this machine is a pin with a small dot. Generally, there is a colored wire on the test clip cable, which is the first wire. Let this wire correspond to pin 1 of the chip. In this way, just check if pin 1 on the test clip and the programmer correspond, and it will be fine to ensure accuracy. When testing the connection of the flat cable with the adapter board, it is also necessary to pay attention to whether each pin on the adapter board is inserted appropriately.

Programming Software Flashing BIOS: After confirming that the chip connection is correct, connect to the computer. Open the programming software

1-- Check to see if the chip information has been read.

2-- Erase, the process is relatively slow, taking only a few dozen seconds.

3-- Check for a blank, confirm the blank check.

4-- Open and select the bin file.

5- Programming, about a few minutes.

6-- Verification, which needs to pass the verification.

After completing the above steps, you can solder the power supply and turn on the machine to check. When there is no power, a few lines of English letters will appear, which is also successful. After charging for a while, it can be turned on normally and enter the system normally.
