As for small parts, the first one I checked at Microchip had a 3x3 mm package, and the first MSP430 I checked at TI had a 4x4 mm package. | |

| Aug 11, 2015 at 5:03 | comment | added | Jimbo | Thank you for your answer. I'm warming up to the microcontroller idea, as I've found a couple of Very Small packages that might be made to fit. If it's bigger than the metal part of a USB 'A' connector, fitment will be a problem. And I have made a basic model, it's just too big. And the current to the load dwindles away as the RC tank winds down. Basically I'm in a rabbit hole & can't find my way out, Google or no. | |
