SHIO88W: common questions

What microcontroller does the SHIO88W use?

The SHIO88W is built around the ESP32-WROOM-32E-N16, from the ESP32 family.

How big is the SHIO88W PCB?

The SHIO88W measures 98.5 × 76.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SHIO88W?

94 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the SHIO88W design files?

From the csabaala/SHIO88W repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SHIO88W design in my own project?

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

Can I test firmware for the SHIO88W 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.
