| Item | Requirement or limit |
|---|---|
| Main board | HubPD, with its fitted side socket and power feed |
| Input | USB-C PD supply offering 20 V, connected to the main board |
| Storage | eMMC on the module, or NVMe for CM5 Lite; no microSD slot |
| NVMe SSD | M-key, 2230 / 2242 / 2280, up to 6 W |
| Fan | Up to 0.4 A; rated to tolerate 5.19 V |
| RTC backup | Raspberry Pi RTC Battery SC1163, rechargeable ML2020 |
| Accessory USB-C | 5 V / 1.5 A |
| Carrier power reservation | 35 W including conversion losses and VCONN |
The service port is for CM5 provisioning and recovery; power comes through the main board. Set PSU_MAX_CURRENT=5000 in the CM5 EEPROM configuration for the accessory USB allowance.
Connect the battery to J104. To enable charging, add this to /boot/firmware/config.txt and reboot:
dtparam=rtc_bbat_vchg=3000000Use this setting only with the specified rechargeable battery. See Raspberry Pi's RTC setup for diagnostics.
With the development tools installed:
mise run //hardware/boards/cm5:lint
mise run //hardware/boards/cm5:fabbuild/boards/cm5/ contains gerbers.zip, bom.csv and cpl.csv. The board is 75.1 × 102 mm and uses the main board's six-layer ordering settings. Select its accessory and service USB-C connectors (J401, J501) in the assembly order.
Use :step for the populated STEP and :preview for board.png. The PCB revision is recorded in the KiCad title block; tag Revision A fabrication files as cm5-rev-a.

It measures 75.1 × 102 mm and has 6 copper layers, 1.57 mm thick.
84 parts, built around the AP3441SHE-7B, LM61480RPHR, TPD4E02B04DQAR and TPD4E05U06DQAR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the hydazz/iasis repository on GitHub, at the commit this page was made from: the board is hardware/boards/cm5/cm5.kicad_pcb and its schematic hardware/boards/cm5/accessory-port.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
