Firefly-RK3288 was one the first boards powered by Rockchip RK3288 quad core Cortex A17 processor, and now Firefly team, part of T-Chip technology, has provided a new version called Firefly-RK3288 Reload with the same processor, but more features, and thanks to design comprised of a carrier board and system-on-module (SoM) – connected via an MXM connector – suitable to people or companies wanting to create their own board without handing the complexity of the processor, memory, and storage part.

Since RK3288 did not suddenly grow SATA or USB 3.0 support, the SATA implementation is based on JMicron JM20329 a USB 2.0 to SATA bridge which should limit data transfer to around 35 to 40 MB/s at best. The system-on-module includes the processor, memory, storage, and PMIC, with signals routed to an 314-pin MXM connector, and most other features are placed in the baseboard. Software supports is basically the same between the two boards, except the Reload version does not support the older Android 4.4 Kitkat firmware. You can find documentation in Firefly-RK3288 Wiki, and download firmware, source code (SDK), and hardware design files (PDF schematics and CAD files) in the Download section of the website.
Firefly-RK3288 Reload can be purchased for $189 including shipping via DHL on Aliexpress. I can’t find Rockchip RK3288 SoM anymore, so you’d have to contact the company to get pricing for the module.
Thanks to Nanik for the tip.
