Microcontrollers on boards using the MCP2561-E/SN
What boards using the MCP2561-E/SN are built for
MCP2561-E/SN: common questions
Where can I find a MCP2561-E/SN reference design?
Each of the 13 boards on this page is a real design using the MCP2561-E/SN. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the MCP2561-E/SN use?
Most are built on AVR/Arduino (7), STM32 (5) and PIC (1).
How big is a typical board using the MCP2561-E/SN?
The median is 80 × 59.5 mm, and 85% are two-layer designs.
What is the most popular open source board using the MCP2561-E/SN?
By GitHub stars, MDE22 by ZeniteSolar, with 2 stars.
Can I simulate one of these boards using the MCP2561-E/SN 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.
