SLAVE TEMP: common questions

What microcontroller does the SLAVE TEMP use?

The SLAVE TEMP is built around the ESP32-DEVKIT-V1, from the ESP32 family.

How big is the SLAVE TEMP PCB?

The SLAVE TEMP measures 90 × 85 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SLAVE TEMP?

22 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the SLAVE TEMP design files?

From the zen451019/MONITOR_HARDWARE repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SLAVE TEMP design in my own project?

The repository has no license, so all rights stay with zen451019. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SLAVE TEMP 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.
