 # LoRa APRS Tracker
 
 The LoRa APRS Tracker will work with very cheep hardware which you can buy from amazon, ebay or aliexpress.
@@ -7,19 +10,8 @@ Try it out and be part of the APRS network.
 
 ## Supported boards
 
-You can use one of the Lora32 boards:
-
-* TTGO T-Beam V0.7 (433MHz SX1278)
 * TTGO T-Beam V1 (433MHz SX1278)
 
-This boards cost around 30 Euros, they are very cheap but perfect for an LoRa iGate.
-Keep in minde: you need a 433MHz version!
-
-## Compiling and configuration
-
-**There is a german [quick start](https://www.lora-aprs.info/docs/LoRa_APRS_iGate/quick-start-guide/) page! Take a look ;)**
