I was specifically thinking of the ATtiny85 when I made my comment. A beginner's first electronics project is often blinking an LED on and off. When I'm teaching a room full of kids electronics for the first time, the simplicity and low-cost nature of the ATtiny chips are hard to beat. I get it, ARM chips are great for real projects, but there is still a place for 8-bit AVR.
- regularfry 6y agoI've literally just received a delivery of through-hole ATTiny85s and a programmer, so I can dead-bug an I2C interface onto an analogue sensor. I have no idea where I'd start looking for an ARM in anything like the same form factor.
- nereye 6y agoThere are through-hole ARM ICs, e.g. see https://hackaday.com/2013/05/29/programming-a-through-hole-arm-microcontroller/ https://hackaday.com/2013/05/29/programming-a-through-hole-a.... For example: https://www.digikey.com/en/products/detail/nxp-usa-inc/LPC810M021FN8129/12102361 https://www.digikey.com/en/products/detail/nxp-usa-inc/LPC81....

- regularfry 6y agoI've just had a quick look, and there are some very small BGA-packaged STM32 chips about. With a competent PCB fab you might be able to knock together a board with 8 jumper pins that wouldn't be much bigger in total than a SOIP attiny, but that's another job plus whatever peripheral components need to be added. Might be a fun design job, though. https://www.mouser.co.uk/ProductDetail/STMicroelectronics/STM32G030J6M6?qs=uwxL4vQweFMe%2Fiu4dY6izA%3D%3D https://www.mouser.co.uk/ProductDetail/STMicroelectronics/ST... looks like it might be a lot of fun, but it's got a 6 month lead time on it.
