## Description

High-performance LoRa solution for long-distance wireless communications, ideal for IoT, remote sensors and monitoring. It operates at 433 MHz with coverage up to 10 km in open field, UART interface with AT commands for quick integration with Arduino and similar boards, adjustable 22 dBm emission power and ultra-low sleep consumption of up to 2 uA.
The M5Stack module with LoRa E220 transceiver is a high-performance wireless communication solution, designed for projects that require long-distance transmissions. Operating at a frequency of 433 MHz, the module can provide communications up to 10 km in open field, making it ideal for IoT applications, remote sensors or monitoring systems. It is fully compatible with Arduino and other development boards, making it easy to integrate into various electronic projects.
The module supports multiple operating modes (Normal, WOR Transmit, WOR Receive and Configuration), providing flexibility depending on the application needs. Transmission is done via the UART interface, with a baud rate of up to 115200 and support for AT commands. Power consumption is optimized, with only 2 µA in sleep mode, which makes it suitable for battery-powered applications.
Specifications:

HY2.0-4P cable: 20cm
Use:
Connect the module to the development board via the UART interface.
Attach the included antenna to ensure stable transmission.
Select the desired mode by configuring pins M0 and M1:
- Normal: M0 Off, M1 Off → data transmission and reception
- WOR Transmission: M0 On, M1 Off → wake-up over the air and data transmission
WOR Reception: M0 Off, M1 On → data reception only
Configuration: M0 On, M1 On → parameter setting via AT commands
Respect the maximum voltage of 5V to avoid damaging the module.
Working mode:
Operating mode | Functionality | Pin configuration (M0 / M1)
Normal | Data transmission and reception | Off / Off
WOR Transmission | Supports wake-up over the air and data transmission | On / Off
WOR Reception | Data reception only (no transmission) | Off / On
Configuration | Allows parameter setting via AT commands | On / On
