Nobo: common questions

What microcontroller does the Nobo use?

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

How big is the Nobo PCB?

The Nobo measures 77 × 34.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nobo?

7 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nobo design files?

From the csabigee/nobo-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nobo design in my own project?

Yes, under the terms of its GPL-3.0 license, which csabigee chose for the repository.

Can I test firmware for the Nobo 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.
