Armpoe: common questions
What microcontroller does the Armpoe use?
The Armpoe is built around the STM32F107XXX-LQFP64, from the STM32 family.
How big is the Armpoe PCB?
The Armpoe measures 3.6 × 3.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Armpoe?
119 components, from 61 distinct parts. The full bill of materials is listed on this page.
Where can I download the Armpoe design files?
From the zeroping/PoE-STM32F107 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Armpoe design in my own project?
The repository has no license, so all rights stay with zeroping. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Armpoe 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.
