From the project
The newest manufacturing revision is B-ES5-MODULAR, a 130 x 100 mm four-layer engineering sample. It keeps ESP32-C6-N16, SHT45, USB-C, 24 V, isolated RS-485, 0-10 V input/output, 1-Wire and contact inputs on the base and moves CO2, VOC/NOx and pressure onto three universal 25 x 2

The symmetric 2x4 connector is electrically safe after 180-degree rotation and each module has its own 3.3 V regulator.
