    There's a whole bunch of ways to charge the cells you've just added to your device – a wide variety of charger ICs and other solutions are at your disposal. I'd like to focus on one specific module that I believe it's important you know more about. You likely have seen the blue TP4056 boards around – they're cheap and you're. Just like with charging ICs, there's many designs out there, and there's one you should know about – the DW01 and 8205A combination. It's so. For a 4.2 V LiIon cell, the useful voltage range is 4.1 V to 3.0 V – a cell at 4.2 V quickly drops to 4.1 V when you draw power from it, and at 3.0 V or lower, the cell's internal resistance. Now you know what it takes to add a LiIon battery input connector to your project, and the secrets behind the boards that come with one already. It's a feeling like no other, taking a microcontroller project with you on a walk as you. Now, you've got charging, and you got your 3.3 V. There's one problem that I ought to remind you about – while you're charging the battery, you can't draw current from it, as the charger relies on current measurements to.
