The RM117-D1E16W0 (ROCK 3 Compute Module SODIMM 1GB RAM / 16GB eMMC Storage) is designed in a DDR2 SODIMM form factor (67.6mm x 32mm).
Because it follows the standard CM3 SODIMM pinout, it can be installed in a variety of industrial and development carrier boards:
Official Radxa CM3 SODIMM IO Board: A primary application board providing access to HDMI, SATA, PCIe, MIPI DSI/CSI, and 40-pin GPIO.
Waveshare Compute Module IO Board Plus: Originally designed for the Raspberry Pi CM3/CM3+, this board is widely used for prototyping with SODIMM modules.
Turing Pi 1: A popular cluster board that supports multiple SODIMM compute modules for edge computing and self-hosting.
Industrial OEM Equipment: Used in existing specialized hardware designed for the Raspberry Pi CM3, such as digital signage players, industrial controllers, and network switches.
Retro Gaming Handhelds/Consoles: Some high-end retro handheld kits designed for the CM3 SODIMM module (like the GPi Case or custom arcade boards) can often utilize this as a "drop-in" performance upgrade.
CPU: Rockchip RK3566 (Quad-core Cortex-A55).
Memory/Storage: 1GB LPDDR4 RAM and 16GB onboard eMMC.
Interface: 200-pin SODIMM edge connector.
Usage Case: higher-performance replacement for the now-aging Raspberry Pi CM3/CM3+ modules in existing systems.
