These are cheaper than 555s, more easily available in various footprints, need almost no supporting passive circuity or glue logic, lower power usage, and more flexible to boot.
Popularity of the 555 waned a long, long time ago.
- thaeli 7y agoMore accurate timers, too. It's bizarre to think that "program a microcontroller" is actually cheaper - even in small quantity - than the 555 designs I remember building as a kid. (In single quantities from LCSC the cheapest 555 is $0.07 and the cheapest Paduak microcontroller is $0.04 - in quantity the 555 is $0.04 and the Paduak is $0.025. Plus fewer support passives with the Paduak.)
- GeorgeTirebiter 7y agoTrue. This is still cool, tho: https://shop.evilmadscientist.com/tinykitlist/652 https://shop.evilmadscientist.com/tinykitlist/652
