O projeto foi concebido para integrar conceitos de eletrônica digital, sistemas embarcados e boas práticas de projeto de placas de circuito impresso, priorizando simplicidade, modularidade e confiabilidade elétrica. Questões relacionadas a firmware são abordadas apenas quando necessárias para justificar decisões de hardware.

O STM32F103C8T6 foi escolhido por oferecer um equilíbrio adequado entre desempenho, custo e disponibilidade. O núcleo ARM Cortex-M3 operando a até 72 MHz é suficiente para aplicações gráficas simples, leitura de entradas e controle de periféricos.

PROJETO-TOPICOS-II: common questions

What microcontroller does the PROJETO-TOPICOS-II use?

The PROJETO-TOPICOS-II is built around the STM32F103C8Tx - MODULE, from the STM32 family.

How big is the PROJETO-TOPICOS-II PCB?

The PROJETO-TOPICOS-II measures 150 × 71.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PROJETO-TOPICOS-II?

36 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the PROJETO-TOPICOS-II design files?

From the LeBaggett/PROJETO-TOPICOS-II repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PROJETO-TOPICOS-II design in my own project?

Yes, under the terms of its GPL-3.0 license, which LeBaggett chose for the repository.

Can I test firmware for the PROJETO-TOPICOS-II 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.
