The SOP8 clip enables in-circuit programming of EEPROM without disassembling the chip, making flashing the BIOS simpler and more efficient. The main purpose of the CH341A Programmer is to back up, erase, program, calibrate and other actions on various software. The SOP8 clip support chip size:Pitch 1.27MM, full range SOP8 wide body and narrow body. The CH341A Programmer support most 24 / 25 Series EEPROM BIOS SOP8 SOP16 chip on the market (Tips:You can see the supported chip models on our website before placing your order).Note:Due to the characteristics of the CH341A chip, the ESMT class 25 chip can only be read and cannot be written. This SOP8 clip is a great solution for burning the chip without disassembling the chip, saving soldering time and making flash BIOS simpler and more efficient. Note for Test Clip: 1.Some motherboards can directly clip the chip, but some chips are affected by peripheral circuits and cannot be operated like this.Check the chip location on the motherboard before purchasing! 2.The test clip can basically be used with many high-power programmers.When a programmer with a protected function is encountered, the clip cannot be read at normal voltage.You need to add a 3.3V voltage. How to use:Hold the chip first, and add a 3.3V voltage to the pin corresponding to the 8th pin of the chip.Generally, the 3.3V power supply has two wires, the VCC is connected to the clip, and the other wire is grounded. 3.Do not forcibly press down when clamping, first open the clip and clip it from the left and right sides of the chip. When disassembling, please don't pull it out directly.First separate the clips left and right, then take them out so that they 't break the tip of the clip. colour:Green+black Material:ABS Package Contents: 1 x CH341A USB Programmer 1 x SOP8 SOIC8 Test ip 1 x 8Pin to 8Pin Converter 2 x SOP8 SOP16 to 8Pin Converter 2 x 2.54mm
