New batch of JeeSMD‘s and Carrier Boards just came in:

Dsc 1918

At last! – this batch took a lot longer than anticipated…

The JeeSMD fixes a nasty error reported in the Talk forums, which had two pins exchanged on the 3.3V voltage regulator.

The reason I missed this, is that I used the JeeSMD on a LiPo battery pack, which runs at around 3.7V – and as it so happens, an MCP1703 will generate a voltage drop of roughly 0.4V when connected the wrong way around. So it all basically worked exactly as expected in my setup.

I bet Mr. Murphy had a major role in this “accidental” design detail…

The Carrier Boards haven’t changed. I simply ran out of the first 100 way faster than I had expected. The good news with the Carrier Board + Box kits, is that I’ve now also got a decent stock of DC jacks, so these will be included with all orders. In fact, I’m also throwing in a DC plug, so you can make your own power cables, or adapt some 5..12V DC power supply to fit these standard 2.1/5.5 mm jacks:

There are several dozen packages waiting for this back-ordered stuff. I’ll get them out in the coming days!
