ESP multi board: common questions

What microcontroller does the ESP multi board use?

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

How big is the ESP multi board?

The ESP multi board measures 82.2 × 47.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP multi board?

43 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP multi board 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 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 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.
