WiFi-Nugget: common questions

What microcontroller does the WiFi-Nugget use?

The WiFi-Nugget is built around the ESP-12F, from the ESP8266 family.

How big is the WiFi-Nugget PCB?

The WiFi-Nugget measures 36 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WiFi-Nugget?

51 components, from 33 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 WiFi-Nugget design files?

From the RakhithJK/WiFi-Nugget-PCB repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the WiFi-Nugget design in my own project?

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

Can I test firmware for the WiFi-Nugget 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.
