HAT CM4 DRC 1: common questions
What microcontroller does the HAT CM4 DRC 1 use?
The HAT CM4 DRC 1 is built around the AXP209, from the AVR/Arduino family.
How big is the HAT CM4 DRC 1?
The HAT CM4 DRC 1 measures 105.6 × 86.1 mm, has 6 copper layers and is 1.76 mm thick.
How many components are on the HAT CM4 DRC 1?
147 components, from 78 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 HAT CM4 DRC 1 design files?
From the ConnectBox/Circuit-Design repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the HAT CM4 DRC 1 design in my own project?
The repository has no license, so all rights stay with ConnectBox. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the HAT CM4 DRC 1 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.
