MistFarm Embedded: common questions

What microcontroller does the MistFarm Embedded use?

The MistFarm Embedded is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the MistFarm Embedded PCB?

The MistFarm Embedded measures 74.4 × 95.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MistFarm Embedded?

56 components, from 42 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 MistFarm Embedded design files?

From the Mistfarm/MistFarm_Embedded 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 MistFarm Embedded design in my own project?

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

Can I test firmware for the MistFarm Embedded 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.
