Wideband controller: common questions
What microcontroller does the Wideband controller use?
The Wideband controller is built around the GD32F103RCTX, from the STM32 family.
How big is the Wideband controller PCB?
The Wideband controller measures 54.1 × 65.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Wideband controller?
129 components, from 57 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 Wideband controller design files?
From the rusefi/rusefi-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 Wideband controller design in my own project?
The repository has no license, so all rights stay with rusefi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wideband controller 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.
