Ok, I digged a bit, and I have a good start :
We need a transceiver module. The module's chip is a NRF24L01, seems popular.
Here is a pair of cheap modules using that chip :

additional vids, same thing, but some additional infos :
different wireless modules explained :
https://youtu.be/vxF1N9asjtsWhile I used a teensy 2 in my last keyboard, the process was quite straightfoward, I'm still lacking practice with arduino and alike, this is progress nonetheless.
I intend to use a Teensy 3.2, it has several pins used for SPI, however, I am a bit lost/conused by the availables pins on it :
- cs
- sck
- din : "Data In" I guess
- dout : "Data Out" I guess
while the pins on the transceiver module are :
- TRQ :
- MISO : Master Input Slave Output master being the MCU (arduino like, here a teensy), and slave the RF module. Connects to the SPI Din pin
- MOSI : Master Output Slave Input, so connects to the SPI Dout pin on the teensy 3.x
- SCK : well that one's easy
- CSN : guess it goes onto the CS pin
- CE :
- VCC : easy enough
- GND : yeah, obvious too
If any of you could point me the right direction that would be great, thanks
