I've been looking on how may I wire all components to create a LiPo Charger based on Wireless Qi
Here are the components I plan to use (the only ones I've found in Stock rigth now otherwise, I might have opted for a All-in-one solution like
This is the Shim to send the 5V for the Pi
https://shop.pimoroni.com/products/lipo-shim
This has a JST connector, and then 3 pins for BAT+, EN and GND
According to the minimal information they provide:
The VBAT+ and GND pins that are broken out can be used as alternative way to inject power, for instance if you wanted to solder on your own JST connector with wires to make it stretch a bit further.
The EN pin can be pulled to ground to cut the power output from LiPo SHIM.
Since this doesn't provide charging capabilities, they recommend getting this

Which has another JST connector, and 4 pins, 5V, GND (I assume 2xGND, one in each side) and BAT
This is the PIN out:
https://learn.adafruit.com/adafruit-mic ... -v2-pinout
And finally the Adafruit Wireless Qi module
https://www.adafruit.com/product/1901
Which brings literally 0 information about the pinouts. In fact most videos I've found are based on the old Adafruit Qi Receiver, with the old brown board (not the new blue one). Judging by the picture of the new one: https://cdn-shop.adafruit.com/970x728/1901-08.jpg
I cannot even know which is the 5V pinout. It says: RECT, SCL, SDA, GPIO and GND.
So I cannot do any good assumptions here, but my best guest is:
1. The LiPo battery is connected to the JST of the LiPo Charger
2. The Qi Module 5V might be the RECT pin, which might be connected to the 5V pin in the LiPo Charger, and the GND with the GND
3. Then the BAT pin in the charger might go into the BAT+ in the SHIM and the other GND to the GND in the SHIM
4. And the other 8 pins of the SHIM soldered to the Pi starting from the top left 5V pin in the Pi.
Still I might do this and blow up the circuits, because I'm just guessing out of pure chance. Have anyone had experience with this wirings?
