Nestbox: common questions
What microcontroller does the Nestbox use?
The Nestbox is built around the STM32L433CCU6, from the STM32 family.
How big is the Nestbox PCB?
The Nestbox measures 85 × 55 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Nestbox?
142 components, from 64 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 Nestbox design files?
From the o16s/anisca-bird repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Nestbox design in my own project?
Yes, under the terms of its GPL-2.0 license, which o16s chose for the repository.
Can I test firmware for the Nestbox without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
