Hey Brad, Download the Picaxe Editor software here, then you can program the chip from there. https://picaxe.com/software/ PS, took a quick look at your boards, but haven't had a chance to test them. Will try and get that done this weekend.
Sorry man, life has been crazy and I just saw this. I did have an issue with email a while ago but it's resolved now. JDH is correct on the SS1. It has a 5V regulator, so you would probably have issues if the voltage gets below 5.2V or so. The SSII and the BF can both run on 5V though.
