Quick soldering pads were common on microcontroller boards like Raspberry Pi Pico. However, a client asked me to design a custom Raspberry Pi CM4 Carrier board with such quick soldering pads on board’s edges. This board has common peripheral interfaces just like as my most other Raspberry Pi CM4 carrier board PCB designs. But it has more powerful 5V 5A power supply and some additional components for CM5 compatibility.
Key Features
- Raspberry Pi Compute Module 5 connector, backward compatible with Compute Module 4
- CM5-only features
- Power on/off tactile button switch
- CM4 and CM5 common features
- 4 x USB 2.0 via 4p quick soldering pads
- 1 x USB Type C for flashing the CM4/CM5
- 1 x HDMI, via FPC connector
- 1 x 4-lane DSI via FPC connector
- 2 x CSI via FPC connector, one of it would be USB 3.0 for CM5
- 1 x PCIe via FPC connector, pinout compatible with Raspberry Pi 5’s PCIe
- 40p GPIO connector for Raspberry Pi HAT
- External 5V power supply input solder pads
