Microcontrollers on boards using the LM3915
LM3915: common questions
Where can I find a LM3915 reference design?
Each of the 3 boards on this page is a real design using the LM3915. 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 LM3915 use?
Most are built on ESP32 (1).
How big is a typical board using the LM3915?
The median is 76.8 × 79.4 mm, and 100% are two-layer designs.
What is the most popular open source board using the LM3915?
By GitHub stars, FPGA-I2S-IIR-Filter implementation by SFMonsun, with 0 stars.
Can I simulate one of these boards using the LM3915 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.
