STM32F103RC has enough processing power even for complex algorithms, and enough timers and other peripheral for 3axis control.
Controller uses mosfets instead of L6234. This allows to use small, light weight mosfets(sot23, sot363) for gopro controllers, and bigger mosfets(so8, D2PAK) for DSLR's, RED's and other big cameras.
