I use this too… but you’ll need an external antenna.
The antenna position within the remote is very sensitive, having it in the wrong place means zero signal for some weird reason.
does this have a 3.3v regulator??
Yes, it takes 6-12V (5V over usb) in and output 3.3V it says on the website so it appears this has a voltage regulator as would also be likely as a seperate regulator for 3.3V is not mentioned in the parts lists.
I think this is the RobotDyn one that Solidgeek also has linked on Aliexpress.

where can you buy those PCB’s bud?
I created them by my own… but these are with totally different hardware.
would this hall sensor work? https://www.ebay.co.uk/itm/HONEYWELL-S-C-SS495A-SENSOR-RATIOMETRIC-LINEAR-/351163597255
Its the sensor from the BOM… so of course it will work if u stick to the basic 5V Arduino nano

@StefanMe I will try out your controller. Despite it Is hard to buy adafruit in Europe.
I am still using Firefly controller at moment and still keep my firefly code up to date.

Looks like it’s a combined SMD and TH module… should work. It’s just a bit bigger than the regular one. Why u wanna use it? Just take the normal one. Or a high quality one…

because it is another 40 days wait for the one listed on the build 
but would it work as a temporary one?
Yes module should work… u can use SMD or TH to connect it.

Any Firefly geeks keen to work on getting telemetry working with the Focbox Unity?
Here’s the post from Jeff (Deodand) where he talks about the change he made to the UART protocol for the Unity.
Am I correct that we would need to make changes to the datatypes.h code in the VescUartControl-new file?

I just ordered a firefly and a unity. Let me know if I can help
Yes this particular nano has dedicated 3.3v regulator underside of the board.
Sorry cbf reading through every solution on this thread - any quick fixes for intermittent cutouts?
I have built the remote and receiver according to this tutorial:
It’s plugged into a unity. I added the power filtering to the receiver today but it didn’t fix the issue. In my skim through this topic I saw a few mentions of adding caps to the receiver Arduino between 5v and gnd. Is that the solution?

Im no expert, but when you say power filtering to the receiver (if u used something like a LC filter), i believe that would have the same effect as the capacitor
If you don’t have a cap on 5v sure add it and see if it helps other than that it could be fluctuations on 3.3v
Making it more compact and durable. Nothing change on parts.
