AABoost

Powering a 5V ATtiny85 circuit...

Seems to work great. Screwed up the button connections, and the inductor footprint. Need to fix in next prototype. On to current draw testing now.

Just got them!

Off to board house soon...

Decided to go with the MCP1640...

Now with snapVCC done, I've rebooted this project. Need to optimise the BOM right from start. Looking at Torex for boost converters. Also need a cost effective connector...

Now that snapVCC is funded, I am getting back to AABoost. I had a very poor experience with ST Microelectronics recently. Sent them a query for which a ticket was created, and weeks later, getting no response, I sent them a tweet with the reference to which they responded as follows:

So I have decided to try and avoid STM parts in my designs. Not that it will matter to them, I suppose.

Confused on whether an LED indicator is needed...

Almost ready to send out for first prototype...
