2.4.1. PPS signal
Support GPS-PPS input for receiving data packets with time stamp.
2.4.2. NRESET signal
The external control circuit can realize the reset of the module. The module can be reset by pulling up the NRESET
level by 0.05~0.2s then releasing it. The NRESET signal is relatively sensitive to interference, and the wiring on the
module interface board should be as short as possible, and should be processed by certain ground.
2.4.3. RX_ON signal
When the receiving state of the module is turned on, this pin outputs a high level, and the on-board LED lights up at
the same time, and connects to the GPIO of the SX1302.
2.4.4. TX_ON signal
When the module is transmitting data, this pin outputs a high level, and the on-board LED lights up, and connects to
the GPIO of the SX1302.
2.4.5. CFG_ON signal
When the module successfully configures the parameters, this pin outputs a high level and the on-board LED lights
up, and connects to the GPIO of the SX1302.
