This adapter can be used to the SPI Flash chip in circuit. That is to say, You can upgrade BIOS of computer motherboard without removing the chip from motherboard. There are many factors that affect the ISP in-circuit programming.One of the main issues is the poor signal quality because many circuits fail to be designed for the in-circuit-programming. The poor signal quality will cause the in-circuit-programming instability or failure. This adapter is designed for the signal enhancement when doing in-circuit programming.There is a signal driver chip that can make in-circuit-programming signal stronger and make programming more .It can greatly the success rate of the in-circuit-programming. This adapter can work on TL866II plus programmer for SPI Flash in-circuit programming. For example: motherboard upgrade for BIOS chip W25X80. It can make the in-circuit programming much easier.Colour:As ShownMaterial:PC+metalPackage Contents:1 x ICSP Enhanced AdapterOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
