Hello community,
I'm looking forward to add Radio controll / synchronize to my teensy LED project.
I am totally new to RF module and used none before
just did some search and read some data with them, there are many different modules/libraries and their key words are different
also there are so many variants even on a same chip name, some QFN, some COB, not sure if there are serious difference that needs to notice.
But I'm quiet sure looking for features below so it best suits my project :
1. I am working with a teensy, so the RF module doesn't need to be programmable.
2. SPI or I2C controllable
3. low currency quiescent mode (~<500uA)
4. the module at low power can wake with correct signal and then wake the (also snoozing) teensy
5. small size, with none of the dimension over 20mm.
6. range: I think a working distance of 5~20m is enough?
7. receivable / transmittable , I wish to let each of the unit can lead and synchronize each other.
(optional)3.3V/5V driven.
(optional2) if the part had a complete library to use that would be great
I did see a nRF24L01, RF75/77 could possibly fit? they look so similar in pinout and size
I'm looking if anyone had experience, or bad experience on any of those modules? or even other suggestions,
Thanks for any sharing
