About the Cm5-carrier v2 PCB

Cm5-carrier v2 is an open source Raspberry Pi PCB design by ben5049, published on GitHub under the AGPL-3.0 license. It is a 6-layer board measuring 70 × 80 mm, with 294 components from 76 distinct parts.

Its main chip is the RP-CM5, from the Raspberry Pi family. Other key parts include the ADS7128IRTER, TVS2701DRBR, TPS26601RHFR, AZV3001FZ4-7 and TPS259470ARPW. By type, the board carries 134 capacitors, 87 resistors, 24 ICs, 17 diodes, 12 connectors and 4 transistors.

From the project

Compact CM5 carrier board with an M.2 E-key connector and a 1000BASE-T1 Ethernet PHY, as well as other optional IO.

- V1 Uses a separate PCIe switch and PCIe-to-Ethernet bridge. It has been abandoned in favour of V2 - V2 Uses the PCI11010C which integrates a PCIe switch and Ethernet MAC, leading to space and power savings compared to V1

Cm5-carrier v2: common questions

What microcontroller does the Cm5-carrier v2 use?

The Cm5-carrier v2 is built around the RP-CM5, from the Raspberry Pi family.

How big is the Cm5-carrier v2 PCB?

The Cm5-carrier v2 measures 70 × 80 mm, has 6 copper layers and is 1.0524 mm thick.

How many components are on the Cm5-carrier v2?

294 components, from 76 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cm5-carrier v2 design files?

From the ben5049/cm-carrier-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Cm5-carrier v2 design in my own project?
