NRF905 module

Post by MrTalon63 » Sat Aug 21, 2021 12:04 pm

Hello,
I recently became interested in microcontrollers and radiocommunication and found this pretty cheap module, but couldn't find any library made for micropython as I'm not yet ready for C++. If anyone knows any, or have any code examples I would appreciate the help. Also, I plan to use it with ESP32 from doit devkit.

Regards

Unless you fancy writing a driver, I would consider the NRF24l01 which has official support.

I see that it is even cheaper and with a good yagi antenna, I could get a range of around 300m. Thanks for suggestion

I have a mostly working driver for the NRF905. I'll publish on my github once it gets a bit more polish.

If you are after performance, I would agree with @pythoncoder and suggest the NRF24L01. It can TX/RX 40x faster, operates up at 2.4ghz, and there's plenty of sample code in the wild.
Be sure to get it from a reputable source, as there's plenty of NRF24L01 clones out there which have sub par performance.
I found the RobotDyn ones to be good quality and original NRF chips.
If your nrf module has a blob of epoxy on it covering the chip, I'd be suspicious.

If you are after a really simple "driverless" connection, there are a few UART based radios too.
eg. HC-11, HC-12, E32-43320DT, E32-915T20D

That is very true - some Chinese ones barely work at all. I have had good results from Sparkfun units.

I once saw a video using the NRF51822, you can watch it if you are interested.
