Connecting RFM69Pi AND official Pi screen

Hi there, any advise?

I have just purchased a RFM69Pi (to provide 433MHz comms). This plugs onto a Pi 4 (I assume, the instructions relate to older Pis) covering the right 10 pins. Pins 1-10, including GND, 5v, SDC and SCL.

The official raspberry Pi screen comes with 4 jump leads, to go to GND, 5v and SDC and SCL. I gather SDC and SDL are needed to make the touch feature work.

Is there a way to make the official touch screen and the RFM69Pi work together?


This might help RFM69Pi V3 - OpenEnergyMonitor Wiki.

RFM69Pi only uses 3.3V, GND and GPIO 14/15 for Rx/Tx and GPIO 4 for reset.

It should be no problem to use SDA and SCL on GPIO2/3. You will just need to rig up some sort of adaptor to make the physical connectors e.g

So the touch screen works without SDA and SCL. I’ve left these out. Not sure what they do.

I’ve taken the neutral to pin 34 on the Pi, and I’ve soldered a 5V connection to Pin 2.

The next question will be whether it fits in the case I’ve ordered for today. Should have it working soon. Touch wood. :slight_smile:

Thought for next version: Do you need to cover pins 1 (3.3v) and 2 (5v) of the Pi, when Pin 4 is also 5v?

It just makes the fitting more stable.
