I'm designing a circuit which consists of a nRF24L01 transceiver and a NeoPixel LED Strip with 3-pin JST PH.
It looks like the Prop-Maker FeatherWing can connect to the LED strip but how can I power and control the transceiver? Am I able to do that from the M0 or M4 feather or do I need an additional FeatherWing to stack on top? If so, which one would that be?
Which Feathers/FeatherWings can connect to a nRF24L01 transceiver?

Re: Which Feathers/FeatherWings can connect to a nRF24L01 transceiver?
The nRF24L01 should work with anything with a SPI interface (which is basically anything). I was using it with Arduino UNO type boards (custom ATmega32 boards). There's a good writeups here https://lastminuteengineers.com/nrf24l0 ... unication/ and here https://www.seeedstudio.com/blog/2019/1 ... ino-guide/.
How you connect it is another matter. You could mount it on a FeatherWing proto and wire it to the pins. With stacking headers, make a Feather stack. See https://www.adafruit.com/product/2884.

Thanks for the response Dave! For the Prop-Maker Featherwing I noticed the rows of pins are 2x12/16 instead of 1x12/16. Does this mean I can have my headers soldered into the outer ones and my transmitter soldered into the correct inner ones? I don't have a lot of height to work with in my container that's holding the electronics so I'd like to avoid stacking a 2nd FeatherWing onto my Feather

Yes, you can use the inner row of holes to connect the nRF24L01.

Hi Dave,
All the parts arrived (M4 Express and Prop Maker) and on closer inspection I'm not quite sure how to connect the transceiver. I have the two feathers stacked and the inner row on the FeatherWing (on top) has M headers sticking out. Looking at the pinouts, I'm not sure which ones I can use it appears they are mapped differently between the M4 and PropMaker. I unfortunately don't understand enough about electronics to be able to sort this out.

Re: Which Feathers/FeatherWings can connect to a nRF24L01 transceiver?
To be precise, you have one feather and one propmaker wing, correct?
I'm not sure what you mean by "inner row on the FeatherWing (on top) has M headers sticking out. " Can you post clear photos?
The pinouts of all Feathers and FeatherWings are the same. That's the key to their interoperability.

Re: Which Feathers/FeatherWings can connect to a nRF24L01 transceiver?
Dave,
I can post a picture once I'm home. In the meantime, I guess what I'm not understanding is for the prop maker wing, it says "Blue - Blue pin for 3W RGB LED - connected through a MOSFET. Connected to D13 on Feather M0 or M4.". Does this mean I can no longer use D13 for other purposes? Another example would be It also looks like the MOSI pin on the M4 is A0 for audio on the FeatherWing. I hope that makes my confusion more clear.

OK. Yes, some of the Feather's pins are used for various Propmaker wing functions. See https://learn.adafruit.com/adafruit-pro ... ng/pinouts
