Agon extender: common questions

What microcontroller does the Agon extender use?

The Agon extender is built around the ESP32-P4NRWxx(QFN104), from the ESP32 family.

How big is the Agon extender PCB?

The Agon extender measures 60 × 90 mm, has 4 copper layers and is 1.578 mm thick.

How many components are on the Agon extender?

329 components, from 105 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 Agon extender design files?

From the bgates747/agon-extender 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 Agon extender design in my own project?

Yes, under the terms of its GPL-3.0 license, which bgates747 chose for the repository.

Can I test firmware for the Agon extender 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.
