Overview
Max MainPCB is an open-source printed circuit board by selina101, from the selina101/CreateLabWork repository on GitHub. It is a 4-layer board of 80 × 70 mm with 33 parts on 25 nets, routed with 113 tracks and 19 vias.
It is built around the INA228AQDGSRQ1. Its parts include 17 connectors, 5 capacitors, 4 ICs, 3 resistors and 1 inductor. It belongs with the ESP32 and RISC-V boards of this library.

In this repo you will find all the work done during the master thesis and during the master valorisation (02/2024-12/2024).
For the PCBs, you will find all the KiCAD files, as well as the gerber files to be able to order PCBs. The file 'PCB library' contains the footprint, the symbols and the 3D models of all the components used for all of the PCBs.
Goat power PCB
Contains the power distribution PCB for Max's robot.
All the components were bought separately and soldered by hand.
Hands
Contains two folders, one with the hall sensors and the other with the FSRs.
For all the Hall sensor PCBs, all the components were bought separately and soldered by hand.
For the FSRs PCBs, there are no components to solder, one only needs to buy the PCBs and cut the velostat.
There is a main PCB that allows for connections. On this PCB, 1206 10kOhm pullup resistors are used, and need to be soldered by hand. If the electrodes are used for a hydrogel, a Adafruit ADS7830 Breakout board is needed.
IMU
The IMU folder contains various versions of the IMU.
IMU_V2 is the round PCB that is used for the squid/tentacle projects. They are also the PCBs that need to be mounted on Max's PCB.
IMU_V3 is the sets of PCBs designed for the Helix type robot. There is the main PCBs that has the space for 2 perpendicular IMUs, the teensy and the I2C Qwiic connectors. There are also the files for the rectangular IMUs.
Both types are accompanied by a pdf explaining everything needed to know for the IMUs.
The IMUs are bought with the top side soldered on by JLCPCB. They have recently changed there classification of these sensors, so they must be bought in larger quantities and in panels because the PCBs are too small otherwise. The minimum quantity for the V3 was 45 IMUs. The back side of the PCBs must then be soldered by hand. For the main PCB, all the components were bought separately and soldered by hand.
MPXH6115AC6U_breakout
Contains the files for the PCBs that Kai asked for, it is a breakout for the MPXH6115AC6U pressure sensor.
Tongue
Contains the files for Benhui's Tongue PCB.
All the components were bought separately and soldered by hand.

Questions
How big is the Max MainPCB PCB?
It measures 80 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Max MainPCB use?
33 parts, built around the INA228AQDGSRQ1. 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 Max MainPCB KiCad files?
From the selina101/CreateLabWork repository on GitHub, at the commit this page was made from: the board is Goat power PCB/Max_MainPCB/Max_MainPCB.kicad_pcb and its schematic Goat power PCB/Max_MainPCB/Max_MainPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Max MainPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask selina101 before reusing the design.
