g613 master control

Four 2*5 reverse-adhesive headers are used to lead out all the pins. The pin definitions have been given. You only need to desolder the 52832 chip of the original main control to it. You can buy new ones directly for other original parts. I have designed a shielding pad of 30*18mm. You can go to Taobao to search for this size. It is not expensive if it is in stock.

Compared with the original 613 main control board, it is smaller and thinner in form, and is also easier to connect to the matrix board and easy to replace.

There is a main control switch onboard. You can buy it by searching Taobao for the ultra-small toggle switch.

As shown in the picture above, using the double-sided reverse pasting process for welding, the two boards can fit perfectly and are very, very thin.
