# ESP32 LoRa APRS Modem
|
|
|
|
|
|
This project is amateur radio ESP32 based LoRa **KISS Bluetooth/BLE/USB/TCPIP** modem + LoRa **APRS-IS RX/TX iGate** server over WiFI + LoRa **APRS digipeater** + **Codec2 DV modem** (with Codec2 Talkie Android application).
|
|
|
|
⚠ **To configure sketch modify default parameters in config.h file.**
|

|
|
⚠ Project also supports **APRSDroid TNC2 text APRS packet mode** (configurable), which makes it interoperable with other LoRa APRS trackers without AX25 support.
|
|
|
|
Supported module types: **SX126X**, **SX127X** and other modules supported by RadioLib.
|
|
|
|
Modules, which are used by users and known to work
|
|
- **SX126X** (**suggested**, 1W modules will provide decent coverage for APRS, stable frequency suitable for < 125 kHz BW at 433 MHz, 5V from USB power bank is enough to power it, has additional LNA)
|
|
- 👍 **E22-400M30S (SX1268)**
|
|
- E220-400M30S (LLCC68) BW125 SF from 7 to 9 (chip limitations)
|
|
- These modules are 30dbm modules, but maximum power should be set to no more than 20-22dbm, see https://github.com/jgromes/RadioLib/wiki/High-power-Radio-Modules-Guide
|
|
- **SX127X** (low power, 50-100mW, temperature frequency drift, problematic for narrow band)
|
|
- RA-01 (SX1278)
|
|
- RA-02 (SX1276)
|
|
- TTGO T-Beam (SX1276)
