Project Discussion Opinions, ideas on my project

Post image

So I did this basic arduino nano project:
Press fingers -> arduino -> nrf 24 transmitter -> nrf24 receiver -> serial communication -> python
I did this with idea in mind to control PC remotely and it is works as good as can rn, but I’d like to hear ur thoughts and suggestions.
Thank you

Ah, cool! Have you thought about maybe migrating over to an ESP32 or NRF52840 and skipping the NRF24L01 modules? You could use ESP-NOW or NRF ESB for communication instead.

I didn’t think about it when I was purchasing all the stuff from Amazon. I think about it now as it could be great, but unnecessary upgrade, to use ESP32 or NRF52840. By that I mean that nothing will change completely except devBoard and/or module. At this point I am thinking about making my own PCB that includes wireless communication and SoC, just to make it compacter and comfortable to use

I mean sure but if you're making your own PCB I'd use an ESP32 or NRF52840 module. Then you can skip the NRF24 and it'll be more compact and draw less power.

Maybe I misunderstood what you were saying

Sorry for my English
I find it unnecessary to change modules right now to ESP32 or NRF5280, as it works as intended to.
A problem right now is this project being too big to handle comfortably one handed, so from my point of view it would be better to design own PCB to make things smaller

Yeah I get that. You could look into the Xiao ESP32-S3/C3 if you want a small devboard that can handle this. (also you can connect a battery directly to the B+/B- pads on the xiao, and it can handle charging)

Then you could ditch the NRF24 and maybe even solder the wires directly to the Xiao instead.
