Sensor bus hat
About the Sensor bus hat
Sensor bus hat is an open source PCB design by sslivins, published on GitHub. It is a 2-layer board measuring 16.5 × 26.5 mm, with 3 components from 3 distinct parts.
By type, the board carries 2 connectors and 1 resistor.
It belongs with the sensors and dev boards & breakouts designs in this gallery.
From the project
Open-source PCB design files for Thermux. There are two boards:
Open-source PCB design files for Thermux. There are two boards:
- Sensor Bus Hat (sensorbushat/) — plugs onto the Olimex ESP32-POE-ISO and breaks the 1-Wire bus out to an RJ45 jack, carrying the bus pull-up resistor. - Temperature Node (tempnode/`) — the distributed DS18B20 sensor breakout with RJ45 connectors for daisy-chaining sensors along the bus.
Each board's gerbers/ folder is self-contained — zip its contents (or upload the folder) to JLCPCB / PCBWay to fabricate that board.

Sensor bus hat: common questions
How big is the Sensor bus hat?
The Sensor bus hat measures 16.5 × 26.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sensor bus hat?
3 components, from 3 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 Sensor bus hat design files?
From the sslivins/thermux 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 Sensor bus hat design in my own project?
The repository has no license, so all rights stay with sslivins. Use it as a reference, and ask the author before reusing the design.
