Hornbill lights: common questions

What microcontroller does the Hornbill lights use?

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

How big is the Hornbill lights PCB?

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

How many components are on the Hornbill lights?

47 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hornbill lights design files?

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

Can I use the Hornbill lights 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 lights 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.
