OpenBCI Wifi Shield: common questions

What microcontroller does the OpenBCI Wifi Shield use?

The OpenBCI Wifi Shield is built around the ESP-12E, from the ESP8266 family.

How big is the OpenBCI Wifi Shield?

The OpenBCI Wifi Shield measures 61.2 × 61.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OpenBCI Wifi Shield?

67 components, from 30 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 OpenBCI Wifi Shield design files?

From the OpenBCI/OpenBCI_Wifi_Shield repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the OpenBCI Wifi Shield design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the OpenBCI Wifi Shield 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.
