This project includes open hardware design files for a DC-SCM compliant PCB that supports System on Modules following the OSM-L standard specified by the SGet group. The DC-SCM follows the interface and mechanical outline described in the 2.1 revision of the DC-SCM standard specified by the Open Compute Project community. Apart from establishing a base DC-SCM compliant platform, the design includes a series of breakout connectors, jumpers and other supplementary circuitry for developing BMC software features for security, reliability, commissioning and benchmarking.
This DC-SCM card has been designed as a carrier board to an L-sized OSM design that combines a Lattice FPGA and an NXP i.MX943 series Application Processor (AP).
The PCB design files were prepared in KiCad 9.x
- Landing pad for OSM-L type of SoM
- Realtek 1Gb Ethernet PHY (Realtek RTL8211FDI-CG)
- ITE IT6251 LVDS-DisplayPort bridge
- USB-C port with FTDI FT4232H for SoM debug and software integration
- USB-C port connected to the OSM-L SoM pads
- USB-C port connected to the HPM
- M.2 (key-M) expansion slot connected to the HPM
- Slot for removable BIOS memories connected directly to the HPM
- Optional on-board TPM connector
