Reliable-Temp-Monitor: common questions
What microcontroller does the Reliable-Temp-Monitor use?
The Reliable-Temp-Monitor is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Reliable-Temp-Monitor PCB?
The Reliable-Temp-Monitor measures 66.9 × 66.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Reliable-Temp-Monitor?
112 components, from 66 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 Reliable-Temp-Monitor design files?
From the Alex-C-EE/Reliable-Temp-Monitor 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 Reliable-Temp-Monitor design in my own project?
The repository has no license, so all rights stay with Alex-C-EE. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Reliable-Temp-Monitor 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.
