We’ve already seen several Rockchip RK3588 modules with Firefly Core-3588J, Turing RK1, and Banana Pi RK3588_CV1, all with an edge connector to insertion into the carrier board. Rongpin RD-RK3588 system-on-module is a little different with four board-to-board connectors that enable a slightly more compact design, and should expose more I/Os than say a 314-pin MXM edge connector.
The module ships with up to 16GB of RAM, 128 GB of storage, a Rockchip RK806-1 PMIC, and the company also offers a development kit with RD-RK3588-B baseboard fitted with the module for evaluation and early software development.
RD-RK3588-C core module specifications:
