Daq: common questions
What microcontroller does the Daq use?
The Daq is built around the Arduino_Mega_Header, from the AVR/Arduino family.
How big is the Daq PCB?
The Daq measures 165.1 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Daq?
76 components, from 36 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 Daq design files?
From the SergioGasquez/daq repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Daq design in my own project?
Yes, under the terms of its MIT license, which SergioGasquez chose for the repository.
Can I test firmware for the Daq without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
