Test-point positions are approximate and were measured manually. Test points may move between CM4 board revisions; TP11 is one known example.
Legend
The CM4 datasheet does not publish a test-point coordinate table.
Signal assignments were verified manually. The available test points appear not to expose 5 V board power, USB, Ethernet, UART, or BOOT. Therefore, powering and flashing the board through these points is unlikely to be possible.
