Nivara: common questions
What microcontroller does the Nivara use?
The Nivara is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Nivara PCB?
The Nivara measures 120 × 79.5 mm, has 4 copper layers and is 0.19 mm thick.
How many components are on the Nivara?
172 components, from 68 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 Nivara design files?
From the WenerrP/WENERR_PACHECO_ELECTIVA_2025_C2 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 Nivara design in my own project?
The repository has no license, so all rights stay with WenerrP. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nivara 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.
