SMUGDESK CM5-NANO-A Carrier Board for Raspberry Pi Compute Module 5, 55×40mm

SKU CH-CR07-QJMSH

Compact 55×40mm carrier board for Raspberry Pi Compute Module 5 with USB 3.2 Gen1, dual 22-pin MIPI 4-lane connectors, 40-pin GPIO and TF card slot for CM5 Lite boot

  • Ultra-compact 55×40mm footprint fits tight enclosures
  • USB 3.2 Gen1 port connects high-speed peripherals
  • Dual 22-pin MIPI 4-lane interfaces link cameras and displays
  • Standard 40PIN GPIO header supports HAT expansion boards
  • Onboard TF slot boots CM5 Lite without eMMC

Nano Carrier Board for Compute Module 5

The SMUGDESK CM5-NANO-A is a 55×40mm carrier board built exclusively for the Raspberry Pi Compute Module 5. It accepts both eMMC and Lite variants, giving developers a minimal footprint for embedded IoT terminals and space-constrained prototypes. The board matches the module outline exactly, so no extra enclosure volume is wasted. Hobbyists needing a full-size desktop replacement should look elsewhere.

Capacity and headroom for embedded workloads

One USB 3.2 Gen1 Type-A port handles flash drives, cameras or HID peripherals at high speed. Dual 22pin 0.5mm FPC MIPI 4-lane connectors support CSI cameras and DSI touch displays for vision applications. A standard 40PIN GPIO header allows stacking HAT modules for sensors, relays or communication add-ons. Projects requiring multiple USB ports, wired Ethernet or PCIe expansion exceed the available interfaces.

Practical limits of the compact form factor

The 55×40mm PCB leaves no room for onboard Ethernet, additional USB controllers or M.2 slots. Power delivery, boot selection and reset are managed through onboard buttons and LEDs rather than external headers. Thermal dissipation relies on the module and enclosure design because no fan header or heatsink mounting points are provided. Builds needing passive cooling surfaces or redundant power inputs cannot be accommodated.

Questions about this item

Will the 55×40mm board fit inside the same enclosure I designed for a bare Compute Module 5?

Yes, the carrier board shares the identical 55×40mm footprint, so it occupies no more space than the module itself.

How can I confirm the USB 3.2 Gen1 port and both MIPI interfaces are functioning after I seat the module?

Connect a USB 3.2 Gen1 device to the Type-A port and attach CSI or DSI peripherals to the two 22-pin FPC connectors; the OS will enumerate them if the links are active.

Does the package include a TF card for booting a CM5 Lite, or must I supply my own?

A micro TF card slot is soldered on the board, but the card itself is not included and must be purchased separately.
