Which microcontrollers do boards using the H7233-1 use?
Most are built on STM32 (2) and RP2040/RP2350 (1).
How big is a typical board using the H7233-1?
The median is 21 × 41.2 mm, and 100% are two-layer designs.
What is the most popular open source board using the H7233-1?
By GitHub stars, Floppy board 3.0 by FloppyO1, with 5 stars.
Can I simulate one of these boards using the H7233-1 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.
