I made it available on GITHUB : https://github.com/ccadic/RFM95LORA_Breadboard
I can connect an I2C Oled Display and an EUI ID number chip (working as a I2C component to read the value)
SMA Edge antenna can be soldered onto the board.

Very nice! thanks for sharing!
My pleasure
Now making the tutorial based on a nodeMCU and then a NanoV3
I have issues with the NodeMcu, not enough Gpio available to run the Oled Screen and RFM95 simultaneously
if you just miss a few GPIO on your Node MCU, there is a possibility to OR the RFM95 DIO0-DIO2 Pins, check https://github.com/hallard/arduino-lmic#dio-pins and the associated schematic.
There is also a schematic for Node MCU where RFM95 and OLED IC2 are used in parallel:
https://github.com/hallard/NodeMCU-Gateway#schematic-lora-version .
Tnx much for the advices. (I’m beginning… lots of things to learn at the same time )
I’ve ordered 2 boards from the links you gave me. It’ll be interesting to learn from exemple
I’ll try and make correction tomorow night
You can also consider to use the LMIC port from Charled Hallard which does not need any DIO or reset at all. He submitted a pull request to the de-facto TTN LMIC stack from Matthijs Kooijman. I understand the Maarten Westenberg (things4u) LMIC port has some nice optimizitions with regard to code size. Didn’t compare this yet with the above ones because they have suited all my needs untill now.
This is awesome. Makes us deliver scaleable nodes with low power and low money
Is there a pcb shield available where i can place a arduino nano v3 and rfm95 to combine?
Hi again, after some browsing on the internet build, i found nothing. i make a new pcb with Fritzing for a nano and RFM95, see picture .
Ordered some prototypes by Aisler. When the prototype works, a copy of the project will be found on github.
You can find this PCB kicad file on the net. It is well tested and works well.
A arduino pro mini is not a nano
Hi . Do you have the link for download the PCB files? I can’t find them. Thank’s
