I wanted to create a functional design charger.
What you need:
- 2xTP4056 LiIon charger modules
- 2+2 contact plates plus / minus
- 2+2 green and red LEDs
- 2 voltmeters
- Micro USB-breakout board
- USB-C breakout board
- Some cable and shrink tube, some filament.
Red shows charging, voltmeters adequate voltage during charging or if not connected the actual voltage of each LiIon cell.
I chose two cells because each TP 4056 consumes approx. 1 A, and typical chargers with USB-A cable can deliver 2A. So more cells wouldn't make sense in my opinion. The existing LEDs need to be desoldered and removed. Red and green LEDs will be connected insead. This is a bit flimpsy, but not too hard. Watch this link:
The case can be printed in MMU-like 2-colors or just omit the text stl, then print it hollow or use both, then print full. The provided case and txt files have larger letters, thus providing better print quality. I use mine, is not too good, but does its job. Let me move to the next project …
I use only micro USB jack, with USB-C I am not too familiar. It did not work for the first time, so I skipped the USB-C in my project. Maybe I wrongly connected it. Doesn*t matter to me.
Printed on V0.1 and Prusa MK3S+ (case+lid) with MMU2s (inserts).
