ARG OSCI HARDWARE: common questions

What microcontroller does the ARG OSCI HARDWARE use?

The ARG OSCI HARDWARE is built around the ESP32-DevKitC, from the ESP32 family.

How big is the ARG OSCI HARDWARE PCB?

The ARG OSCI HARDWARE measures 113 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ARG OSCI HARDWARE?

56 components, from 45 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 ARG OSCI HARDWARE design files?

From the ArgOsciProyect/ARG_OSCI_HARDWARE 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 ARG OSCI HARDWARE design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the ARG OSCI HARDWARE 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.
