Hornbill our: common questions

What microcontroller does the Hornbill our use?

The Hornbill our is built around the ESP-WROOM-32, from the ESP32 family.

How big is the Hornbill our PCB?

The Hornbill our measures 93 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hornbill our?

68 components, from 31 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 Hornbill our design files?

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

Can I use the Hornbill our design in my own project?

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

Can I test firmware for the Hornbill our 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.
