The main controller is THEAJS32 SoC hich 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, ho ever some are reserved
for internal communication.
