a high quality of power supply for the whole module. Input 28V power is transform to 12V
and then 3.3V for the total system. The inner MCU use the SPI interface communicate with
the 2.4G transceiver. The Excellent matching circuit in RF-Front ensures that the signal has
minimal signal loss and radiation. The MCU provides the UART interfaces and transform to
RS485 interface to communicate with the baseboard.
