FireBeetle ESP32-E and LoRa RFM95 module, how to connect ?

userHead FredFit 2023-02-06 22:49:04 1151 Views6 Replies

Hello,

I'm currently using a RFM95 LoRa module (based on a SX1276 chip) with a LOLIN D32 board. The SPI connections between both are made according to the pinout in the following table. It does work well, but I plan to replace the LOLIN D32 by an ESP32-E FireBeetle board because of its much better performances in Deep Sleep mode. Can someone help me in finding the pins that are missing in my table below ? Unless I've not seen them, I cannot find details about the SPI pinout of the FireBeetle. Thanks in advance!

 

RFM95    LOLIN D32    FIREBEETLE

SCK         18                      18

MISO       19                      19

MOSI       23                      23

NSS           5                         ?

RST          14                        ?

DIO0          2                         ?

The tutorial referenced contains a link to code. Looks like it works but the code link does'nt work.

I've tried everything to chase it down but it's gone,

Also I've tried for two days now to get the FireBeetle to work with it's own cover (TEL0125) but nothing works. If anybody has code please let me know.

Interfacing LoRa RA-02 Transceiver Module with ESP32

Step 1: Circuit. The following circuit shows how you should connect ESP32 to the LoRa RA-02 module. Connect wires accordingly.Step 2: Library. Install the following library on your Arduino. ...Step 3: Code. Upload the following code to the ESP32 board of receiver side.

I think I've found myself the answer after having viewed the following video, and found out that the TL0125 LoRa board is also based on a SX1276 chip. The TL0125 consists only on hosting the SX1276 chip and providing its pins to the ESP32.  

So, refering to this video, my previous table could become:

 

RFM95   FIREBEETLE (pin #)

SCK           18

MISO         19  

MOSI         23 

NSS           27

RST           26

DIO0         13 

 

(In my case DIO0 will not be wired since I'll be using the ESP32 as a LoRa transmitter)

 

Could someone please confirm that I'm right, thanks in advance!

 

And one last question: is the TL0125 suitable for both Firebeetle ESP32 (DFR0478) AND ESP32-E (DFR0654) ?

Edit fixed! Don't try to insert a table in your topic :)
