Hello evrybody. Difference between Rock960 and Rock960C?

Board based on the Rockchip RK3399 - ARM Cortex-A72 Dual-core up to 1.8GHz + Cortex A53 Quad-core up to 1.4GHz

What’s the major difference in Rock960A/B vs Rock960C in the baseboard and the Expansion connector?

Is it possible to test the dual MIPI camera in Rock960A/B/C board?
