What boards using the LD1117STR are built for
LD1117STR: common questions
Where can I find a LD1117STR reference design?
Each of the 4 boards on this page is a real design using the LD1117STR. 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 LD1117STR use?
Most are built on ESP32 (1), PIC (1) and STM32 (1).
How big is a typical board using the LD1117STR?
The median is 113.8 × 99 mm, and 50% 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.
