Banda Magnetica: common questions
What microcontroller does the Banda Magnetica use?
The Banda Magnetica is built around the PCMF2HDMI2SZ, from the STM32 family.
How big is the Banda Magnetica PCB?
The Banda Magnetica measures 37 × 73 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Banda Magnetica?
56 components, from 47 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 Banda Magnetica design files?
From the WilliamSanchez/Hardware 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 Banda Magnetica design in my own project?
The repository has no license, so all rights stay with WilliamSanchez. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Banda Magnetica 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.
