The Rechargeable Li-Po Battery Board (R.L.B.B.) will be a PCB that serves two functionalities, charging batteries and supplying power to other loads through a battery's energy storage. For the former, the board will serve as a charging circuit for a rechargeable Lithium Polymer (Li-Po) battery, connecting to an external power source (wall outlet, power supply, etc). The second functionality involves connecting the battery to a boost voltage regulator, to provide a 5V nominal power supply to an attached device. The board will feature a physical switch to alternate between charging/discharging modes, in addition to including clear labels for operation. I would expect that this project will be useful as a “mini power bank”, in order to charge small devices (toys, etc.) using the Li-Po battery to different kinds of connections. This prototype will likely have a fixed connector type, but this connector can be wired to other devices. I would expect future designs of the prototype to consider an adaptable array of connections to charge devices (such as a bundle of different commonly-used cables that route to a fixed end of the PCB). Project Requirements: 1. The project will include a custom designed PCB, featuring connectors for a 18650 format Li-Po battery housing and an external load. - MET. 2. The project's main circuit board (not including battery housing or connected loads) will be 2.25" x 2.25" (length x width) in dimensions or less. - MET. 3. The project, in discharging mode, will output a nominal voltage of 5V (+/- 0.5V), with a steady current of at least 95 mA. - MET. 4. The project will utilize the following components: a MCP73832T-2DCI/OT Charging controller, and an AP3012KTR-G1 boost step-up voltage converter. - MET.
