Previously, this has been done using breadboards and veroboard. This suffered from issues with fitting the microswitch pins into the breadboards and mounting the board to the robot. + +As such, this PCB is designed to be a simple breakout board for a microswitch. It has footprints for a microswitch, debouncing circuitry and a 3-pin screw terminal to connect to the board. The board is designed to be mounted on 2020 aluminium extrusion chassis with M5 screws. + +![3D PCB](https://sourcebots.github.io/microswitch-hw/3D/switch_pcb-3D_blender_top.png) + +![PCB front](https://sourcebots.github.io/microswitch-hw/Presentation/boards/switch_pcb-front.svg) +![PCB back](https://sourcebots.github.io/microswitch-hw/Presentation/boards/switch_pcb-back.svg) + +![Schematic](https://sourcebots.github.io/microswitch-hw/Schematic/switch_pcb-schematic.svg) + +## Resources + +- [Schematic PDF](https://sourcebots.github.io/microswitch-hw/Schematic/switch_pcb-schematic.pdf) +- [Interactive BOM](https://sourcebots.github.io/microswitch-hw/Assembly/switch_pcb-ibom.html) +- [BOM CSV](https://sourcebots.github.io/microswitch-hw/BoM/Generic/switch_pcb-bom.csv) +- [Gerbers (JLCPCB format)](https://sourcebots.github.io/microswitch-hw/Manufacturers/switch_pcb-_JLCPCB_compress.zip) +- [3D model (STEP)](https://sourcebots.github.io/microswitch-hw/3D/switch_pcb-3D.step) +- [Assembly drawings](https://sourcebots.github.io/microswitch-hw/PCB/PDF/switch_pcb-assembly.pdf) \ No newline at end of file
