Which microcontrollers do boards using the AT24C256 use?
Most are built on RP2040/RP2350 (2) and STM32 (1).
How big is a typical board using the AT24C256?
The median is 95 × 88.6 mm, and 75% are two-layer designs.
What is the most popular open source board using the AT24C256?
By GitHub stars, ReST32 Main by berryelectronics, with 7 stars.
Can I simulate one of these boards using the AT24C256 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.
