Which microcontrollers do boards using the LM1117 use?
Most are built on NXP (2), ESP8266 (1), ESP32 (1) and Microchip SAM (1).
How big is a typical board using the LM1117?
The median is 100 × 123 mm.
What is the most popular open source board using the LM1117?
By GitHub stars, Duet 2 by Duet3D, with 257 stars.
Can I simulate one of these boards using the LM1117 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.
