ESP multi board cuadrada: common questions

What microcontroller does the ESP multi board cuadrada use?

The ESP multi board cuadrada is built around the ESP-12, from the ESP8266 family.

How big is the ESP multi board cuadrada?

The ESP multi board cuadrada measures 61 × 35.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP multi board cuadrada?

24 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP multi board cuadrada design files?

From the CRM-UAM/ESP_Multi_Board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP multi board cuadrada design in my own project?

The repository has no license, so all rights stay with CRM-UAM. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP multi board cuadrada 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.
