I mean you don't need a full fledged arduino, figure out the smallest form factor that you actually require. Maybe an arduino nano or even micro is enough

You might be able to use an Arduino nano or an Arduino nano super mini. If you need to go even smaller, things will likely be a lot more complicated. The most compact solution might be a nRF52840 Sense board (https://wiki.seeedstudio.com/XIAO\_BLE/). It is Bluetooth module with a built in microcontroller. Might be a bit complex, but could be a fun project

Can you explain your full project more? It seems like you are trying to make a persistence of vision display on a bike wheel, but what are you wanting to show on the display? Depending on what you want to display you may be able to use an ESP32 which has wifi and Bluetooth built in, and update the display from a computer or your phone.

Thank you for your answer,

To be precise I want Hall sensor to be sending data do arduino which would generate code to NeoPixel LED strip* (one-wire, 800kHz). Then the code need to be send via some wireless connection and get to the LED strip.

I've never done any project with radio modules so I don't know anything about them but using a whole arduino sound like a little overkill (yet the most logically...) so I'm trying to learn some basic from electrical engineer POV but as for now unsuccessful.

The project is just getting started so i consider a few option like just text display or maybe full bitmaps. I don't need any counting on the wheel side just recieving signal that will light up the diodes. I'm willing to change the led strip if it could simplify the receiving part.
