README.mdProtoBoard V0.2
A small board (48 x 56 mm) for great gloves !
- Still a work in progress, current version does NOT work *
Features
Pros :
- ESP32S3 dual core
- Small (48x56 mm)
- Power from 2S to 4S lipo (accept 6.5 volt up to 20 volt)
- Can use Wifi (doesnt use ADC2)
- 16 ADC input
- RGB Header
- 5V 5A for Servo for up to 5 Servo
- Support up to 7 LRA
- Battery protection (integrated BMS : overcharge, overdischarge and overcurrent protection)
- Battery level (via voltage divider)
- Cheap to build
- Use 2.54 mm header
- USB C for programming (The board CANNOT be powered via USB)
Cons :
- Compoment on both side => more expensive to produce in small quantity in pcb fab (bottom side have easy to solder components)
- Doesnt charge the battery
- PCB is 4 layer (a bit more expensive than 2 layer PCB)
Buy the PCB
This design does NOT work right now, do NOT buy it unless you can debug it by yourself You can buy the board via PCBWay using the file ProtoBoard.kicad_pcb.zip and the BOM ProtoBoard.xlsx.
TODO
- Add pinout

Questions
How big is the ProtoBoard PCB?
It measures 56 × 48 mm and has 4 copper layers, 4.69 mm thick.
What parts does the ProtoBoard use?
96 parts, built around the ESP32-S3-MINI-1-N8, DRV2605LDGS, TCA9548ARGER and CD74HC4067SM96. 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 ProtoBoard KiCad files?
From the ciborg971/ProtoBoard repository on GitHub, at the commit this page was made from: the board is ProtoBoard.kicad_pcb and its schematic ProtoBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProtoBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
