Which microcontrollers do boards using the LM2902 use?
Most are built on STM32 (5), ESP32 (3) and Microchip SAM (1).
How big is a typical board using the LM2902?
The median is 110.5 × 100 mm, and 77% are two-layer designs.
What is the most popular open source board using the LM2902?
By GitHub stars, DAC ADC PWM IO by DanielMartensson, with 180 stars.
Can I simulate one of these boards using the LM2902 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.
