Microcontrollers on boards using the UMH3N
What boards using the UMH3N are built for
UMH3N: common questions
Where can I find a UMH3N reference design?
Each of the 9 boards on this page is a real design using the UMH3N. 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 UMH3N use?
Most are built on ESP32 (9).
How big is a typical board using the UMH3N?
The median is 114.1 × 70.3 mm, and 11% are two-layer designs.
What is the most popular open source board using the UMH3N?
By GitHub stars, R2 HH Controllers by greghulette, with 2 stars.
Can I simulate one of these boards using the UMH3N 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.
