Schematics and design for soil MFC voltage and current sensing

The goal of this project is to create an autonomous robot called PAMI. This directory contains the PCB and the code uploaded to the microcontroller that allows PAMI to operate independently. To do this, we must code the motors for the wheels (with control law), the obstacle detector, and the stop button.
Pami 2026 V2 is an open-source printed circuit board by ARCLille, from the ARCLille/PAMI_2026 repository on GitHub. It is a 4-layer board of 80 × 62 mm with 28 parts on 31 nets, routed with 240 tracks and 56 vias.
It is built around the JS102011SCQN. Its parts include 7 resistors, 7 connectors, 5 capacitors, 2 ICs and 1 switch. It belongs with the robots and motor control boards and the ESP32 and RISC-V boards of this library.

DRWJSCHMIDT/T41
This is the repository for the officially released V10, V11, and V12 versions of the T41 Software Defined Transceiver hardware and kits.
It measures 80 × 62 mm and has 4 copper layers, 1.58 mm thick.
28 parts, built around the JS102011SCQN. 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.
From the ARCLille/PAMI_2026 repository on GitHub, at the commit this page was made from: the board is KiCad/pami_2026_V2.kicad_pcb and its schematic KiCad/pami_2026_V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ARCLille before reusing the design.
