Tindie Weblog | The AmpRipper for Energy-Hungry Tasks


There are numerous LiPo charging circuits, however that is the primary I’ve seen that’s so highly effective and versatile. The AmpRipper 4000 helps charging at as much as 3A and outputs as much as 4A through USB-C or giant through-hole pads. It breaks out I2C communication pads for the MAX17048 battery monitor, permitting your microcontroller mission to watch the facility provide. The hooked up microcontroller may also begin and cease charging, overriding the default behaviour if wanted.

The primary output additionally has a swap, which is a pleasant characteristic to have co-located with the facility provide and cost circuitry. This removes the necessity to your board to have any energy provide circuitry in any respect until you want decrease voltages like 1.8 or 3.3V. This makes it an ideal companion for boards just like the Raspberry Pi, BeagleBone Black, or any single-board pc. With this board and a Pi400, you’ll be able to simply have a completely moveable cyberdeck!

In case your battery helps it and also you add an non-obligatory heatsink, you’ll be able to improve the cost present past 3A by altering a resistor worth. The vendor additionally affords a model with the heatsink already fitted. Additionally, you’ll be able to add a thermistor to your battery so the cost controller can forestall overheating the battery. Enter voltage may be as excessive as 14V, however any respectable USB-C charger ought to be capable of put out the present wanted. The included energy provide for the Pi400 is an ideal match. And at beneath 40mm x 50mm, it will possibly match into small areas whereas nonetheless packing a punch!
