OneroiV1: common questions
What microcontroller does the OneroiV1 use?
The OneroiV1 is built around the ESP32-S3-WROOM-1U-N4, from the ESP32 family.
How big is the OneroiV1 PCB?
The OneroiV1 measures 50 × 75 mm, has 4 copper layers and is 1.596 mm thick.
How many components are on the OneroiV1?
160 components, from 70 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 OneroiV1 design files?
From the HomeOnDuna/Nyx-Flight-Computers 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 OneroiV1 design in my own project?
The repository has no license, so all rights stay with HomeOnDuna. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the OneroiV1 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.
