RM117-D2E32W3, Okdo ROCK 3 Compute Module SODIMM (CM3 SODIMM) Model A 2GB/32GB / Wi-Fi/BT

The OKdo ROCK 3 Compute Module SODIMM (CM3S) Model A is a highly impressive device that offers an array of features within its compact design. It’s based on the Rockchip RK3566 System on Chip (SoC), which boasts a robust CPU, a Power Management Unit (PMU), DRAM memory, eMMC storage, as well as wireless connectivity through WiFi 4 and BT 4.2. All these components are packed into a compact DDR2 SODIMM form factor, measuring just 67.6mm x 32mm.

The CM3S is a cost-effective, and highly versatile solution for a wide range of applications. Despite its small size, this device is a true powerhouse. This variant offers 2GB of LPDDR4 RAM and a 32GB eMMC storage, as well as Wi-Fi and Bluetooth configuration.
The CM3S accelerates product development by providing a powerful SoM in a compact form factor. With a simple carrier board (a 2-layer baseboard is sufficient to provide access to all functions of the SoM), engineers can rapidly develop solutions and prepare the boards for production.
Please note: The images above show a CM3S-specific model. This model has certain features like wireless communication capabilities or eMMC. Depending on the purchased SKU there might be variations to the populated components.
