Reflow oven: common questions

What microcontroller does the Reflow oven use?

The Reflow oven is built around the STM32F302R8TX, from the STM32 family.

How big is the Reflow oven PCB?

The Reflow oven measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Reflow oven?

83 components, from 38 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 Reflow oven design files?

From the edenbarby/reflow-oven repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Reflow oven design in my own project?

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

Can I test firmware for the Reflow oven 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.
