ROMs would be useful for storing lots of data for long periods of time without corruption or freeing up space on your SSD for more hot data, that could be automated. They should be cheap and compact. These are useful properties.
I’ve never seen this website before, it seems useful. Thank you.
The super cheap padauk microcontrollers are very cheap and cool. Eevlog did some videos on them. https://odysee.com/@eevblog:7/eevblog-1306-1-of-5-3-cent-padauk-micro:b
They are very cool, but they’re a bit too weak for me. I started off with an 8-bit Arduino Uno, but now use exclusively 32-bit microcontrollers. I have 5 picos that I got with a slight discount that I’m using for my projects. I really like the RP2040, so the pico is an obvious choice. Also, I don’t really use C/C++ to program my microcontrollers, I use and contribute to TinyGo, which is not going to work on the more obscure devices. However, they do seem like really nice chips for when you just want a really cheap device to perform some logic.
Yeah I’ve thought about porting Teacup firmware to an ultra cheap 3D printer board I’d make. But I think these micros are intended for cheapo products. If your product costs more than like ~$20 you might want to invest in a nicer micro. But I haven’t used them yet although I have some sitting around. I can’t comment on how good they actually are.
I’ve only really used Atmel micros but I’ve found their pricing is a little steep. Yeah there are some value Arm M0’s… GigaDevice has some riscv stuff that may be good.
Actually you read now about them making plastic chips.
That could be interesting maybe applied to memories.
