I nwas about talking about digispark (attiny85) board that would be a good match for rolling out mysensors if only had a couple more pins: [image: 1498271391008-s-l300.jpeg] I was asking if it's possible to use them after all one way or another, at least for basic sensors with 3 pins (GND, Vcc, Signal) from which we need only Signal. I also mentioned this as known, but unwated solution: https://www.hackster.io/arjun/nrf24l01-with-attiny85-3-pins-74a1f2
