Raspberry Pi 5 Compute Module Microscope PCB

A custom carrier board for the Raspberry Pi Compute Module 5, purpose-built for digital microscopy. The board breaks out the CM5’s camera interfaces, provides regulated power rails, drives LED ring illumination with PWM brightness control, and interfaces to stepper motor drivers for motorised stage positioning — putting a capable imaging and compute platform onto a single, compact PCB.

Designing around a compute module (rather than a full SBC) allows the carrier to be tailored precisely to the application, reducing size and eliminating unnecessary peripherals.

Key aspects:

  • High-speed differential signal routing (MIPI CSI camera lanes)
  • Multi-rail power supply design for CM5 and peripherals
  • PWM-controlled illumination with adjustable intensity
  • Stepper driver interface for XY/Z stage control
  • Full PCB layout in KiCad
