When designing a DIY electronics challenge, the way you provide energy – e.g. a battery and charging circuit – typically comes late within the design course of. In any case, folks have been powering tasks for a few years. That half must be simple.
Or so that you would possibly assume. This basic energy provide expertise continues to evolve. For those who want one thing that matches your wants completely, typically the answer is a brand new customized board just like the one DIY GUY Chris made.
His circuit connects to a USB-C energy provide and passes the suitable energy alongside to a battery by way of a BQ24075 charging IC. The board then takes energy from the battery and boosts it as much as 5V with a PAM2401 IC.
It’s a comparatively easy idea. The board ought to permit a nominal 3.7V battery to produce a clear 5V output all the way down to .9V (when almost useless), then cost it appropriately time and again. And it does the job… after a big little bit of troubleshooting seen within the challenge video beneath.
Along with exhibiting off the cost/increase circuit design, the video outlines DIY GUY Chris’ course of when it didn’t fairly work as he’d deliberate. This meant first mitigating a solder bridge, however there was truly a extra basic drawback with the board that took some investigation to search out. Nonetheless, this too was simply fastened as soon as discovered.
I received’t spoil the video totally (see simply earlier than 12:00 for the reveal)… however bear in mind to test your drawings should you’re going to recycle a circuit part in your schematic!
