Adau1492: common questions
What microcontroller does the Adau1492 use?
The Adau1492 is built around the ESP32-WROOM-32U, from the ESP32 family.
How big is the Adau1492 PCB?
The Adau1492 measures 113 × 77 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Adau1492?
171 components, from 61 distinct parts. The full bill of materials is listed on this page.
Where can I download the Adau1492 design files?
From the fabguitar69690/FreeDSP-Aurora-Custom repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Adau1492 design in my own project?
The repository has no license, so all rights stay with fabguitar69690. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Adau1492 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.
