Dac shield: common questions
What microcontroller does the Dac shield use?
The Dac shield is built around the ARDUINO_SHIELD, from the AVR/Arduino family.
How big is the Dac shield?
The Dac shield measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dac shield?
31 components, from 22 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dac shield design files?
From the visgence/dac_shield repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dac shield design in my own project?
The repository has no license, so all rights stay with visgence. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dac shield 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.
