Which microcontrollers do boards using the ATtiny45-20SU use?
Most are built on AVR/Arduino (4), ESP8266 (1) and STM32 (1).
How big is a typical board using the ATtiny45-20SU?
The median is 69.5 × 39 mm, and 80% are two-layer designs.
What is the most popular open source board using the ATtiny45-20SU?
By GitHub stars, MIST.1010 by UzixLS, with 43 stars.
Can I simulate one of these boards using the ATtiny45-20SU 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.
