1. Instructions for use: The total length of the clip is about 42CM.
The clip chip should be opened as much as possible, the red edge corresponds to the 1 pin of the clip chip, and the blue board is marked with 1 plug-in programmer 1 pin, these two points are correct. .

Before buying: Some boards can directly clip the chip, but some boards can’t do this, because the chip will be affected by the peripheral circuit on the board, please know before shooting, so as not to buy it back and not use it, but the chip will be soldered down. It can be used directly as a universal seat, and both wide and narrow bodies are common.

Many high-power programmers can basically be used normally (such as: Weilong, Zhou Ligong, Sylt and other external power programmers)

When encountering a programmer with a protected function, the clip cannot be read under normal voltage.
At this time, a 3.3V voltage needs to be added.
The method is: The clip clamps the chip, corresponding to the 8th pin of the chip Apply a 3.3V voltage to the clip pin.
Generally, the 3.3V power supply has two wires, so the VCC corresponds to the clip, and the other wire is directly grounded.
