OH137: common questions
Where can I find a OH137 reference design?
Each of the 1 boards on this page is a real design using the OH137. 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 OH137 use?
Most are built on ESP32 (1).
How big is a typical board using the OH137?
The median is 185 × 58.6 mm, and 0% are two-layer designs.
What is the most popular open source board using the OH137?
By GitHub stars, Microbot v1.1 by Freimor, with 0 stars.
Can I simulate one of these boards using the OH137 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.
