README
README.mdvoidboard
custom esp32 devboard with extensive power management and a built-in IMU
why I made this
I needed devboards for some of my projects that would benefit from extensive power management, and rlly wanted to make the starter project but it was too expensive, so I decided to completely overhaul it and make my own from scratch, in the process creating this.
what it is
it is a devboard based on the esp32-s3 wroom mini 1, a module containing the s3 SoC as well as flash, a clock and an antenna (routing the antenna was the only reason I didnt go with a bare SoC and the rest of the components). I added extensive PD, including a usb c port for PD and data, an in-built battery connector with different ICs to switch between them for power, and also an IC to tell battery charge. it has a white indicator LED in the center (one of the best things on the board) with a sich void portal thingy around it as silkscreen art which I drew in like 20 mins in procreate.
JLPCB order is 97 usd, BOM is as a csv (md coming later) and is just the parts on the devboard. I am ordering PCBA with the smaller ICs I cannot hand solder and will likely just solder the pins and some of the larger ICs (the wroom module/0402 caps/resistors/IMU/smaller ICs are too small/complicated to solder by hand)

Questions
How big is the Devboard PCB?
It measures 30 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
44 parts, built around the ESP32-S3-MINI-1-N8, DW01A, MAX17048G+T10 and ME6211C33M5G-N. 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 Devboard KiCad files?
From the dark-Phoenix2077/voidboard repository on GitHub, at the commit this page was made from: the board is voidboard PCB/devboard.kicad_pcb and its schematic voidboard PCB/devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask dark-Phoenix2077 before reusing the design.
