SDM-24 Data Logger: common questions
What microcontroller does the SDM-24 Data Logger use?
The SDM-24 Data Logger is built around the USBLC6-2SC6, from the STM32 family.
How big is the SDM-24 Data Logger PCB?
The SDM-24 Data Logger measures 101 × 75 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the SDM-24 Data Logger?
110 components, from 61 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 SDM-24 Data Logger design files?
From the sundevilmotorsports/pcb-dev 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 SDM-24 Data Logger design in my own project?
The repository has no license, so all rights stay with sundevilmotorsports. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SDM-24 Data Logger 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.
