Black Body Temperature Sensor: common questions
What microcontroller does the Black Body Temperature Sensor use?
The Black Body Temperature Sensor is built around the STM32G431RBT6, from the STM32 family.
How big is the Black Body Temperature Sensor PCB?
The Black Body Temperature Sensor measures 62 × 77 mm, has 6 copper layers and is 1.5584 mm thick.
How many components are on the Black Body Temperature Sensor?
206 components, from 58 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 Black Body Temperature Sensor design files?
From the DylanLockyer/Black_Body 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 Black Body Temperature Sensor design in my own project?
Yes, under the terms of its MIT license, which DylanLockyer chose for the repository.
Can I test firmware for the Black Body Temperature Sensor without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
