Tobias’s original ‘Funky’ had voltage regulator, that I removed in my version in favor of a voltage step-up circuit. How about having both on the Funky and you will decide which one to use depending on the concrete application? Well, I managed to squeeze in a voltage regulator, while keeping the step-up circuit. Another change that I made is that I connected the CLK output from the RFM12B module to the ATTiny84’s CLKI, so I can test if I can run it off the RFM’s 10Mhz crystal. Here is how it worked out:
I will order few test PCBs and see how it works.
