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.

IDM-RoomSensor-ESP-B-ES3-C6: common questions
What microcontroller does the IDM-RoomSensor-ESP-B-ES3-C6 use?
The IDM-RoomSensor-ESP-B-ES3-C6 is built around the ESP32-C6-WROOM-1-N16, from the ESP32 family.
How big is the IDM-RoomSensor-ESP-B-ES3-C6 PCB?
The IDM-RoomSensor-ESP-B-ES3-C6 measures 130 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the IDM-RoomSensor-ESP-B-ES3-C6?
80 components, from 56 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the IDM-RoomSensor-ESP-B-ES3-C6 design files?
From the Xerolux/IDM-Smart-Climate-Platform repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the IDM-RoomSensor-ESP-B-ES3-C6 design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which Xerolux chose for the repository.
Can I test firmware for the IDM-RoomSensor-ESP-B-ES3-C6 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
