Boilerplate USB single Lithium cell battery power supply for DIY projects

<< < (3/3)

Peabody:
There's a Great Scott video on a TP5410 module.  He found several shortcomings, including lack of any battery protection.



jonovid:
just found this lot of module strips in my parts bins of a 2017 vintage  :-[ when they was cents in the dollar so you'd buy a strip of 5 or 10 at a time
one strip is Li-lon battery charger with protection chip  :-+ the others are Li-lon battery DC to DC set to 5 volt converter USB power  :-\ :-/O
mini modules DC to DC 3.3volt for a never completed drone camera set-up.   dander & hair in the image is from the cat.  :palm: only used 3 modules back in 2017
something to play with   no excuses now ::)
