STM32H743
ARM Cortex-M7 · 480 MHz
2 × BMI088
Independent IMUs + SPL06-001
4 layers
50 × 45 mm · KiCad 10
3S–6S
LiPo · 10–30 V
01 / Design challenge
Bringing control, sensing and connectivity together on a compact board.
The design has to accommodate a fast processor, two independent IMUs, onboard logging and multiple interfaces while retaining a 30.5 × 30.5 mm mounting pattern. Component placement, power distribution and routing all matter on a four-layer PCB.
02 / Engineering approach
From schematic to fabrication-ready files.
Processing architecture
STM32H743VIH6, two Bosch BMI088 sensors on separate SPI buses and an SPL06-001 barometer.
Power & interfaces
5 V and 9/12 V buck rails, dedicated sensor LDOs; USB-C, GPS, ESC, UART and SWD.
Fabrication package
Four-layer PCB, schematic, Gerber/Drill files, BOM and pick-and-place coordinates published in the repo.
