EspMessenger: common questions

What microcontroller does the EspMessenger use?

The EspMessenger is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the EspMessenger PCB?

The EspMessenger measures 51.3 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EspMessenger?

3 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the EspMessenger design files?

From the usini/espMessenger repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the EspMessenger design in my own project?

Yes, under the terms of its MIT license, which usini chose for the repository.

Can I test firmware for the EspMessenger 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.
