The CM4 Flash Jig is a production fixture for flashing Raspberry Pi Compute Module 4 modules. It is designed for teams that need to program multiple modules reliably using the 100-pin mezzanine connectors.

The jig combines mechanical alignment, controlled power, USB boot handling, status indication, and automated flashing into one repeatable operator workflow.

What It Is For

Use this jig when you need to:

• prepare CM4 eMMC modules in small-batch or production workflows;

• reduce manual handling and avoid repeated use of the Compute Module mezzanine connectors;

• make the flashing process repeatable for operators;

• catch basic electrical or boot issues before a module leaves the station;

• keep traceable records for each flashed module.

Key Features

• Automated stand self-test before production starts.

• Image flashing to CM4 eMMC through Raspberry Pi USB boot mode.

• Power rail and total DUT current measurement during the cycle.

• Boot check after flashing.

• Built-in display for simple operator guidance.

• HardPy web interface for detailed progress, measurements, logs, and failure reasons.

• Local database and StandCloud report storage.
