SmartHarz-Tracker (English|Deutsch weiter unten)

A LoRaWAN tracker based on the Lilygo T-Echo.

The T-Echo is based on following components:

• Nordic Semiconductor nRF52840 MCU
• SemTech SX1262 LoRa Tranceiver
• Quectel GNSS L76 module
• an 200*200px e-paper display
• a user button
• a touch button
• (optional) Bosch Sensortec BME280

As Meshtastic and SoftRF are available for the T-Echo already, a tracker was the next logical step. Especially as we are currently have a number of Dragino LGT-92 trackers deployed at the fire departments of Goslar. As the LGT-92 is sadly EOL we are looking for a good replacement and the T-Echo is looking promising and offers even more features.
