About the IDM-RoomSensor-Classic-B-ES1 PCB

IDM-RoomSensor-Classic-B-ES1 is an open source AVR/Arduino PCB design by Xerolux, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 145 × 78 mm, with 22 components from 19 distinct parts.

Its main chip is the ATtiny1616-SNR, from the AVR/Arduino family. Other key parts include the TSR 1-2450, SHT45-AD1B-R2, MCP4725A0T-E/CH, OPA197IDBVR and AP2112K-3.3TRG1. By type, the board carries 6 ICs, 6 capacitors, 5 resistors, 2 connectors, 1 fuse and 1 diode.

It belongs with the sensors designs in this gallery.

From the project

The orderable PCB revision is B-ES1, a bench-test engineering sample using an ATtiny1616, SHT45, MCP4725 and OPA197. It is powered from the protected 24 V input and provides a passive KTY81/210 path plus a nominal 0-10 V humidity output.

What microcontroller does the IDM-RoomSensor-Classic-B-ES1 use?

The IDM-RoomSensor-Classic-B-ES1 is built around the ATtiny1616-SNR, from the AVR/Arduino family.

How big is the IDM-RoomSensor-Classic-B-ES1 PCB?

The IDM-RoomSensor-Classic-B-ES1 measures 145 × 78 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IDM-RoomSensor-Classic-B-ES1?

22 components, from 19 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-Classic-B-ES1 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-Classic-B-ES1 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-Classic-B-ES1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
