PCB AMR: common questions
What microcontroller does the PCB AMR use?
The PCB AMR is built around the STM32F407VGTX, from the STM32 family.
How big is the PCB AMR?
The PCB AMR measures 142.9 × 100.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PCB AMR?
103 components, from 49 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 PCB AMR design files?
From the ManuelOrtizCamacho/PCB_AMR repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the PCB AMR design in my own project?
The repository has no license, so all rights stay with ManuelOrtizCamacho. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PCB AMR 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.
