Heater: common questions

What microcontroller does the Heater use?

The Heater is built around the L7805, from the ESP32 family.

How big is the Heater PCB?

The Heater measures 138.1 × 62.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Heater?

28 components, from 22 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 Heater design files?

From the AbdELRahmanGamiel/PcbDesignsHw 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 Heater design in my own project?

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

Can I test firmware for the Heater 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.
