AccelerationDataLogger: common questions

What microcontroller does the AccelerationDataLogger use?

The AccelerationDataLogger is built around the STM32F072CBTx, from the STM32 family.

How big is the AccelerationDataLogger PCB?

The AccelerationDataLogger measures 78.1 × 78.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AccelerationDataLogger?

85 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the AccelerationDataLogger design files?

From the Toroid-io/AccelerationDataLogger repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the AccelerationDataLogger design in my own project?

Yes, under the terms of its GPL-3.0 license, which Toroid-io chose for the repository.

Can I test firmware for the AccelerationDataLogger 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.
