Microcontrollers on boards using the MCP2551-I-SN
What boards using the MCP2551-I-SN are built for
MCP2551-I-SN: common questions
Where can I find a MCP2551-I-SN reference design?
Each of the 10 boards on this page is a real design using the MCP2551-I-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 MCP2551-I-SN use?
Most are built on STM32 (6), AVR/Arduino (3) and ESP32 (1).
How big is a typical board using the MCP2551-I-SN?
The median is 74.3 × 56.7 mm, and 90% are two-layer designs.
What is the most popular open source board using the MCP2551-I-SN?
By GitHub stars, NMEA2000Adapter-8.1 by peterantypas, with 444 stars.
Can I simulate one of these boards using the MCP2551-I-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.
