Introduction

smôl is a new board format and, as the name suggests, they're really small!

The smôl Power Board LiPo is an intelligent power board for smôl. It provides 3.3V power for your smôl stack from a Li-Ion / Li-Polymer battery and has a built-in charger and fuel gauge.

Each smôl board measures just 1.60" by 0.42" (40.6mm by 10.7mm). We made the boards just wide enough so we could squeeze USB-C and 16-way Flexible Printed Circuit (FPC) connectors on there. Some of the boards have components on both top and bottom layers which again helps keep the boards small.

smôl boards are designed to stack one on top of the other, using 16-way 0.5mm-pitch FPCs to provide the interconnect from one board to the next. Each board has an IN FPC connector on the bottom layer and an OUT FPC connector on the top layer. The boards stack in a zig-zag daisy chain; signals and power are passed from one board to the next up and down the chain through the FPCs.

Required Materials

As a minimum, you're going to need a Lithium-Ion / Lithium-Polymer rechargeable battery to go with your power board:

The Power Board LiPo is part of the smôl ecosystem. Why not pair it with one of the smôl Processor Boards and a Peripheral Board?

Don't forget that you will need Flexible Printed Circuits to connect your smôl boards together. You're going to need one FPC per board. Our 36mm FPC is the perfect length if you want the smôl boards to stack neatly, one on top of the other.
