Wrong SX1278 module - what are my options?

1

Hi,
I ordered by mistake a SX1278 module which has only 8 connected pins.
When trying to connect to an ESP32 I realize that I need other pins from chipset :frowning:
Except de-soldering the chipset, do I have other options to use this module for OMG?
Thank you

I think you should be OK. The CC1101 only needs 8 pins, but you may need to add a new definition for them.

What MCU are you using?

Having a quick look at the code and your pinout you will also need pins DIO1 and DIO2

DIO1 is used in the module definition

      new Module(RF_MODULE_CS, RF_MODULE_DIO0, RF_MODULE_RST, \
                 RF_MODULE_DIO1

And DIO2 for raw input

#  define STR_MODULE "SX1278"
#  ifndef RF_MODULE_RECEIVER_GPIO
#    define RF_MODULE_RECEIVER_GPIO RF_MODULE_DIO2
#  endif

rf.initReceiver(RF_MODULE_RECEIVER_GPIO, RF_MODULE_FREQUENCY);

Without it, it won’t work, maybe try and solder to wires from the module pins/pads (6 & 7)?

This was the first one I made, had to solder a lot more and soldering is my worst skill, it works, and prob. the best of all mine made.

Thank you! I will try soldering the missing wires.
