MCP73831: common questions
Where can I find a MCP73831 reference design?
Each of the 17 boards on this page is a real design using the MCP73831. 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 MCP73831 use?
Most are built on Nordic nRF (4), AVR/Arduino (3), STM32 (2) and ESP32 (1).
How big is a typical board using the MCP73831?
The median is 61.5 × 74 mm, and 88% are two-layer designs.
What is the most popular open source board using the MCP73831?
By GitHub stars, TK44 by Ladniy, with 45 stars.
Can I simulate one of these boards using the MCP73831 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.
