MeArm-Wireless: common questions

What microcontroller does the MeArm-Wireless use?

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

How big is the MeArm-Wireless PCB?

The MeArm-Wireless measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MeArm-Wireless?

27 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the MeArm-Wireless design files?

From the mimeindustries/MeArm-Wireless-PCB repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MeArm-Wireless design in my own project?

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

Can I test firmware for the MeArm-Wireless 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.
