First, I think capture suit contains following parts.
I think jacket can use zip for base cloth design. The most important design is to fix the sensors.
Make some pocket with zip maybe a good idea. My K-Ceptor is 55mm55mm17mm with case.
And maybe wires can hide with cable tray with zip between nearby K-Ceptor.
I use a custom pcb design for Chordata Hub, it use CM4 for computing module. Lite version of this PCB design will open source (Lite version will remove USB Type-A port, audio jack, HDMI, Ethernet RJ45).
I will attach this pcb to capture suit.
This PCB design include the functionality of Chordata Hub and a power switch, use 18650 power bank with PH2.0 connector, and USB Type-C, it will switch between this two power input online without power off the system.
I suggest to use Hub hat with Raspberry pi with capture suit, if you don't have this special PCB (This design haven't opensource now, I am so busy for work and some live streaming software.)
