E220-900T22S LLCC68 LoRa Wireless RF Module 22dBm ISM band 850.125~930.125MHz LoRa Spread Spectrum SMD IPEX Antenna Anti-interference

[IC]:LLCC68

[Frequency]:850.125~930.125MHz

[Power]:22dBm

[Distance]:5km

[Size]:16*26mm

[Introduction]:E220-900T22S is a new generation of LoRa wireless serial port module (UART), based on Semtech's original LLCC68 chip design. It has a variety of transmission methods, works in the (850.125~930.125MHz) frequency band (default 873.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.

3 GND - Ground
4 GND - Ground
5 M0 Input(weak pull-up) Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded)
6 M1 Input(weak pull-up) Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded)
7 RXD Input TTL UART inputs, connects to external (MCU, PC) TXD output pin
8 TXD Output TTL UART outputs, connects to external RXD (MCU, PC) input pin
9 AUX Output Used to indicate the working status of the module;The user wakes up the external MCU and outputs low level during power-on self-check initialization; (can be left floating)
