3.3V power input
E106-915G27P2 module uses 3.3V power supply. In TX mode, the maximum instantaneous peak current may reach
400mA. In order to prevent voltage drop, the switch power supply or LDO used shall be able to provide enough current,
and a tantalum capacitor or electrolytic capacitor with large capacitance value shall be added at the power supply port of
the module. If switching power supply is used to supply power to the module, the circuit wiring shall avoid the antenna
part as much as possible to prevent EMC interference.

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.
