K230-104 main control Rapoo V860 positioning plate opening lightless hot-swappable base

 K230-104 standard key master Rapoo V860 positioning plate opening without light (supports other 104 keyboard positioning plate pedicure itself, the PCB length is 424*119, which is relatively small)

First print the main control connection pins to test the size and test the order channel. .

Then various paintings. . I also referred to many documents shared by great masters. (After drawing the circuit several times and laying out the PCB, I started over when the components I put in did not meet the Lichuang printing standards. In total, I drew about 5 versions of this print. It took more than 10 days to get started for the first time)

The new version of the 2 sets of switches reserves a 2.54 toggle switch under the space bar. The left side is DC power supply   and the right side is a switch that can be connected to the main control (tested. The DC switch can be used to achieve the pairing of Youlian. The main control switch is always on. Just turn it on)

This is the main control DC power connection position. It is easier to wire by digging holes for testing. (The flying wire position above is the key positioning plastic screw of another keyboard)
