Looking at the pictures, the inductor is nearly as wide as the circuit board which is about 10mm. However the documentation for the PSPMAA0402-4R7M-ANP inductor indicates that it is only...
Hi thank you for making these files and schematics available! Do you have any suggestions on part numbers that should fit with the existing layout for the USB PWR CONNECTOR...
Hi, First of all, thanks for sharing these circuits! I am mainly interested in the solar charger. As I see it, the battery output feeds directly to the booster circuit....
Maybe I'm mistaken but it looks like you have 2-3 boards that are similar but backwards of what I want. I think they are taking a USB C input and...
Hello, I would really like to use this module for recycling old power supplies to charge USB-C. I tried to make a test batch of boards with JLCPCB but the...
In LiPo_Charger_LS_TP4056_schematic.pdf we can see the power path doesn't have USB charger 5v as input. Maybe I'm wrong but shouldn't be the load supplied by the charger will the USB...
It would be nice to see also a PD Trigger with a cheap MCU which allows to set a target voltage, but with a buck and boost converter on board,...
The reference implementation in http://www.injoinic.com/wwwroot/uploads/files/20200221/0405f23c247a34d3990ae100c8b20a27.pdf shows the resistor between BAT and the battery connector, but https://github.com/wagiminator/Power-Boards/blob/master/LiPo_Power_Board_IP5306/LiPo_Power_Board_IP5306_schematic.pdf has R4 towards ground. There are also a few deviating values. I'm not sure...
Hey, first off: Thanks a lot for these boards! They are a great reference for newcomers, me included. I especially like the explanations of design decisions and the clean schematics....
