Which microcontrollers do boards using the LD1117STR use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the LD1117STR?
The median is 100 × 100 mm, and 67% are two-layer designs.
What is the most popular open source board using the LD1117STR?
By GitHub stars, Midi grid by zukaitis, with 92 stars.
Can I simulate one of these boards using the LD1117STR 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.
