I have recently saw a very cheap module on online shops.

those are very cheap 10pcs 6$ (including shipping). wondering if anyone has made any library of it.

That are normal NRF24L01+ modules. They are about 1 dollar each, but now even cheaper !

I think the 'Mirf' library was used in the past, but I don't know if it has been maintained.

You can try the RadioHead library : RadioHead: RadioHead Packet Radio library for embedded microprocessors

Perhaps you can start here : Arduino Playground - Nrf24L01

After digging a while i have found out that the module contains SE8R01 chip.
I have got the datasheet of the module.

There are almost too many libraries for nRF24L01+
See my project for some links

Most seem to start with Maniacbug's work
