It's a smÃ�´l world!\u003c\/p\u003e \u003cp\u003eThe smÃ�´l Power Board AAA is an intelligent power board for the smÃ�´l ecosystem. Designed to boost the voltage from one or two AAA or AA cells up to 3.3V, you would expect this board to have a TPS61200 regulator on it, and indeed it does. (That's the same regulator we use on our \u003ca href=\"https:\/\/www.sparkfun.com\/products\/10255\"\u003eLiPower - Boost Converter\u003c\/a\u003e.) But you probably wouldn't expect it to have an AVR ATtiny43 microcontroller on it. So why have we included one?\u003c\/p\u003e \u003cp\u003eThis is an \u003cem\u003eintelligent\u003c\/em\u003e power board for smÃ�´l. The power board takes control of the 3.3V power for the whole smÃ�´l stack. The processor board can then instruct the power board to put the entire smÃ�´l stack into deep sleep for a pre-defined interval. Sleep intervals of 10's of milliseconds to several days are possible. In deep sleep, the only device left powered is the ATtiny43 and that reduces the current draw to \u003cstrong\u003e12µA\u003c\/strong\u003e. Yes, you read that right, 12 microamps! smÃ�´l makes it possible for your battery life to be measured in \u003cstrong\u003emonths\u003c\/strong\u003e not days!
