Which microcontrollers do boards using the OPTO_TRANSISTOR use?
Most are built on AVR/Arduino (1) and STM32 (1).
How big is a typical board using the OPTO_TRANSISTOR?
The median is 44.3 × 29.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the OPTO_TRANSISTOR?
By GitHub stars, Armpoe by zeroping, with 4 stars.
Can I simulate one of these boards using the OPTO_TRANSISTOR 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.
