Pcb: common questions

What microcontroller does the Pcb use?

The Pcb is built around the ESP8285, from the ESP8266 family.

How big is the Pcb?

The Pcb measures 43 × 40.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

65 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb design files?

From the PinkFluffyUnic0rn/stm32flight repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pcb design in my own project?

Yes, under the terms of its GPL-3.0 license, which PinkFluffyUnic0rn chose for the repository.

Can I test firmware for the Pcb 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.
