RC Servo CNC I/O Module

### Features

- 4 Standard RC Servos
- Switch to select servo power from the 6 Pack 5V supply to an external supply (on terminal block).

### Buying assembled from JLCPCB

They will only assemble one side. You should specifiy the top side. You must purchase and solder the 12 pin header on the bottom. It is a standard 0.100" (2.54mm) pitch header. You can buy snap off style many places or the exact part here. LCSC part number C225487

You also need to buy the mating terminal block (Ningbo Xinlaiya Elec. XY2500F-A-5.0-2P) from LCSC

Both those parts are on the BOM of the schematic.

### PCB Specs

You can use all of the defaults. I typically change the solder mask to black for 6 Pack modules.
