A second module i made breadboard friendly using a 16 pin dip IC socket. The RFM95 module was joined to the IC socket with wires.

The antenna output was not connected to the dip socket. I added a 8,2 cm wire as antenna to this module.

I used a 16 pin version as this 16 pin socket that i had in stock has a better connection to the breadboard than the 14 pin version.
I have plans to use the 3 spare pins later to add some components. E.g. one pin connected to DIO0, DIO1 and DIO2 with diodes as used in some circuits / one or more leds (power led) or some sensor(s). Before adding this items want to do some tests first on a breadboard.

DIO1 | MISO |
DIO0 | MOSI |
3.3V | SCK |
DIO4 | NSS |
DIO3 | RESET |
GND(1) | DIO5 |
ANA(2) | GND(1) |

(1) GND all connected to one GND
(2) Antenna (wire antenna, not to 16 pin socket)
To test this module i wired it to a Wemos D1 mini the same way as my First (One Channel) LoRa Gateway, adapted the sketch (name of gateway/server) and uploaded it.
On the breadboard you can already see some diodes as used in some circuits and also a push button. They are not used in the circuit. Only the wire connections as in my first RFM95 - Wemos D1 mini LoRa gateway where made. This circuit worked just as my first 1CH gateway !!
Connections (for 1CH LoRa gateway):
RFM95 pin | Wemos D1 mini (ESP8266) pin |
3.3V | 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 |
