2 open source boards using the MCP4921-EP
Real designs built with the MCP4921-EP, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

Most are built on AVR/Arduino (1).
How big is a typical board using the MCP4921-EP?
The median is 142 × 83.8 mm, and 50% are two-layer designs.
What is the most popular open source board using the MCP4921-EP?
By GitHub stars, PCDU Load Tester v1 by UChicago-Space-Program, with 1 stars.
Can I simulate one of these boards using the MCP4921-EP before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
