Microcontrollers on boards using the EL3H7
What boards using the EL3H7 are built for
EL3H7: common questions
Where can I find a EL3H7 reference design?
Each of the 6 boards on this page is a real design using the EL3H7. 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 EL3H7 use?
Most are built on RP2040/RP2350 (5) and STM32 (1).
How big is a typical board using the EL3H7?
The median is 109.6 × 98.8 mm, and 67% are two-layer designs.
What is the most popular open source board using the EL3H7?
By GitHub stars, Iw-8-controller by mekatrol, with 0 stars.
Can I simulate one of these boards using the EL3H7 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.
