I now have the TinySensor v1.4 in my hands, there are some small improvements over the version I last published, most notably that I added a 3.3V FTDI connector. You can’t use it to program the Attiny (..yet, I am working on that too), but it provides serial debug connectivity plus power source. Quite handy when you develop.
The PCB fab-house messed up the silk screen and used the placement layer instead of t_silk layer, so I got pretty much useless silk screen, but that’s no serious problem other than aesthetics.
My first build of the TinySensor v1.4 is to replace the home-etched PCB for RFM12b-to-serial for Raspberry Pi project:
I applied a bit of hot silicon glue to couple points, where there is a risk of potential contact between the TinySensor and the Pi, isolation band can be used as well:

The v1.4 is available for sale in the store
