The main controller is THEAJS32 SoC which operates at a frequency of 100MHz. It includes VEGA ET1031
Microprocessor, 256KB internal SRAM, Three UARTs, Four SPIs, Three TIMERs, Eight PWMs, Three I2C
interface, 32 GPIOs. Most of its pins are connected to the external headers, however some are reserved for
internal communication
.
