Integralstick: common questions
What microcontroller does the Integralstick use?
The Integralstick is built around the STM32F777NIH6, from the STM32 family.
How big is the Integralstick PCB?
The Integralstick measures 87 × 59.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Integralstick?
266 components, from 51 distinct parts. The full bill of materials is listed on this page.
Where can I download the Integralstick design files?
From the azonenberg/integralstick repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Integralstick design in my own project?
Yes, under the terms of its BSD-3-Clause license, which azonenberg chose for the repository.
Can I test firmware for the Integralstick 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.
