VR-Hall
About the VR-Hall PCB
VR-Hall is an open source PCB design by rusefi, published on GitHub. It is a 2-layer board measuring 49 × 52 mm, with 52 components from 14 distinct parts.
Other key parts include the MAX9924UAUB+, 74HC2G17GW and 74LVC2G86. By type, the board carries 26 resistors, 12 capacitors, 8 diodes, 4 ICs and 2 connectors.
From the project
Problem statement: do do not have x8 or x10 position sensor inputs on stm32, in order to handle any combination of x5 hall and x3/x5 VRs we would need to mix each VR with Hall
Problem statement: do do not have x8 or x10 position sensor inputs on stm32, in order to handle any combination of x5 hall and x3/x5 VRs we would need to mix each VR with Hall
We are looking to confirm that VR signal (in this case from MAX9924) could be mixed with Hall signal into same/shared digital signal

VR-Hall: common questions
How big is the VR-Hall PCB?
The VR-Hall measures 49 × 52 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the VR-Hall?
52 components, from 14 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 VR-Hall 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 VR-Hall 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.
