Block Diagram
The control signals from/to the MCU and the Semtech LR1110 are:
1 x SPI, coming from the MCU to the LR1110 SPI interface
LR1110 interface Reset / IRQ / Busy line
I2C coming from the MCU to the accelerometer sensor
GPIO for the Hall Effect sensor and user button
Control lines for RF switch:
Two from the MCU, for GNSS antenna diversity and Wi-Fi/BLE selection.
One from the LR1110, for LoRa RX/TX path selection.
