Which microcontrollers do boards using the BL1551 use?
Most are built on ESP32 (1).
How big is a typical board using the BL1551?
The median is 81.1 × 27.6 mm, and 100% are two-layer designs.
What is the most popular open source board using the BL1551?
By GitHub stars, Esp2400 by m24h, with 6 stars.
Can I simulate one of these boards using the BL1551 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.
