MSS Stereo LPF PS and LFO board: common questions
What microcontroller does the MSS Stereo LPF PS and LFO board use?
The MSS Stereo LPF PS and LFO board is built around the TL072, from the STM32 family.
How big is the MSS Stereo LPF PS and LFO board?
The MSS Stereo LPF PS and LFO board measures 170.2 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MSS Stereo LPF PS and LFO board?
79 components, from 52 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 MSS Stereo LPF PS and LFO board design files?
From the JordanAceto/msm_stereo_LPF 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 MSS Stereo LPF PS and LFO board design in my own project?
The repository has no license, so all rights stay with JordanAceto. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MSS Stereo LPF PS and LFO board 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.
