TTN single channel gateway with esp8266 for us frequency plan at 903.9Mhz
My region is fit for TTN 923 frequency plan, before making a 923 1ch gateway, it's good exercise to 1st make a 915 gateway. Hardware: RFM95, ESP8266 I did not find the hardware guide for V5, but there is one for V4 http://things4u.github.io/HardwareGuide/Single-Channel-Gway/ESP-gateway-v4.html short notice on hardware: The version is done with 2 kinds PCB(3 in V5, additional heltec board) which related to pin connection.There are' Comresult connections: For the bare board solutions the connections that need to be made are as follows: RFM95 pin ESP8266 pin 3.3V VCC 3.3V GND GND MISO D6 GPIO12/MISO MOSI D7 GPIO13/MOSI SCK D5 GPIO14/CLK (*) NSS D8 GPIO15/CS RESET *nc DIO0 D1, GPIO5 DIO1 D2, GPIO4 DIO2 D3, GPIO0 (**) * The reset pin does not have to be connected so it seems. It is only used at setup to read the chip identification ** This connection is not necessary for the current version of the gateway, but is more versatile for next versions or other use ...
