[Power]:19~20dBm

[Distance]:3.0km

[Interface]:UART

[Introduction]:E32-433T20D is a wireless serial port module based on Semtech's SX1278 RF chip Block (TTL level), transparent transmission mode, working in the 410-441MHz frequency band (default 433MHz), using LoRa spread spectrum technology.

1
Pin No. Pin Item Pin Direction Pin Application
1 M0 input (very weak pull-up) cooperates with M1 to determine the 4 working modes of the module. (Cannot be left floating, can be grounded if not used)
2 M1 input (very weak pull-up) cooperates with M0 to determine the 4 working modes of the module. (Cannot be left floating, can be grounded if not used)
3 RXD input TTL serial input, connect to external TXD output pin; Can be configured as open-drain or pull-up input, see parameter settings for details.
4 TXD output TTL serial output, connect to external RXD input pin;Can be configured as open-drain or push-pull output, see parameter settings for details.
5 AUX outputs Used to indicate the working status of the module; (can be left floating)The user wakes up the external MCU, and outputs a low level during the power-on self-test initialization;It can be configured as open-drain output or push-pull output, see parameter settings for details.
6 VCC input Positive reference of module power supply, voltage range: 2.3~5.5V DC
7 GND Input Module ground wire
