ESP-Hiro: common questions

What microcontroller does the ESP-Hiro use?

The ESP-Hiro is built around the ESP-12E, from the ESP8266 family.

How big is the ESP-Hiro PCB?

The ESP-Hiro measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP-Hiro?

79 components, from 34 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 ESP-Hiro design files?

From the Chrismettal/ESP-Hiro 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 ESP-Hiro design in my own project?

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

Can I test firmware for the ESP-Hiro without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
