Electrical circuit
UPD 09/22/2024: Schematic modified (added connection to USB shield and make connectors DNP), so the old one you can find in git history
Output current
IOUT = 1200*(VPRG/RPRG)

Test with notebook PD charger
There is already exist USB-C vesion of the TP4056 charger, but that chinese board don't support supply form PD chargers.
By the way, possibility to use PD charger it's the main reason of creation custom board.
Full KiCad Project
UPD 09/22/2024: Project updated to KiCad 8 with some improvements
- add: gitignore
- update: from kicad 6 -> kicad 8
- update: all symbols and footprints to local libraries
- add: rule courtyard exception for DNP connectors
- fix: USB-C connector shield connection to GND
- fix: CC1 and CC2 to resistor 5.1k

R1 — can be 0 Ohm, recommend 0.2 Ohm – 0.4 Ohm
R5, R6 is for LED's current limitation, can be used 4.7k-5.1k;
R4 is for set maximum output current, may lower;
RK1 is NTC thermistor for battery temperature control, replace it by 0 Ohm resistor (short it);
