Info
A pi pico clone with a battery charge and protect IC.
originally this was going to be a version that contains a battery charge IC and a ESP32 wireless slave but I feel like its a bad idea to combine things Ive not worked on before so I scaled back the project to have just a battery PMIC.
problems
I must point out that alike most things on my github im learning as I go so some pointers on doing things correctly would be apreciated.

Questions
How big is the EnvPicoLiPo PCB?
It measures 21.2 × 51.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EnvPicoLiPo use?
57 parts, built around the RP2040, BQ24072RGTR, SKRKAEE020 and 1N4002W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the EnvPicoLiPo KiCad files?
From the Envious-Data/EnvOpenPico repository on GitHub, at the commit this page was made from: the board is RP2040/EnvPicoLiPo/EnvPicoLiPo.kicad_pcb and its schematic RP2040/EliteMicro2040/EliteMicro2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnvPicoLiPo design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
