It has a higher +charge rate than the on-board charger on [TeleMetrum](../TeleMetrum), and +will be necessary for charging the batteries used with projects like +[TeleNano](../TeleNano) and [TeleMini](../TeleMini), which do not have +on-board charging capability. + +## Features ## + +### User View ### + +* Wall-wart power supply to our standard 2mm LiPo battery connector +* 1.0 x 0.4 inch board + +### Developer View ### + +* Hardware Features + * [Microchip MCP73837](http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en531507) Li-ion battery charger chip + * Strain-relief holes for soldering to wall-wart leads +* Tools Used + * [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout +* Licenses + * The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html) + +## Artifacts ## + +The design files can be found on [git.gag.com](http://git.gag.com) in the +project [hw/lipocharger](http://git.gag.com/?p=hw/lipocharger;a=summary). + +## Future Plans ## + +We need to build and evaluate some prototypes, and review costing, before +deciding whether this design will go into production. |
