MR 228A SPI SUB Controller

The MR-228A TTL sub-control system is the third-generation new solution product for the night scene lighting project. Using more high-end FPGA chips, it supports higher computing speed, larger storage space, and can be expanded to support more load channels. Support 8-port output, support maximum 120Hz frame rate output. Support overcurrent and overvoltage protection, surge protection 1.5KV and other features. Long-term operation in high and low temperature harsh environments.
