DataProcessingUnit: common questions

What microcontroller does the DataProcessingUnit use?

The DataProcessingUnit is built around the STM32F103RBTx, from the STM32 family.

How big is the DataProcessingUnit PCB?

The DataProcessingUnit measures 85 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DataProcessingUnit?

48 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the DataProcessingUnit design files?

From the RobertGawron/HardwareDataLogger repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DataProcessingUnit design in my own project?

Yes, under the terms of its MIT license, which RobertGawron chose for the repository.

Can I test firmware for the DataProcessingUnit 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.
