Admittedly this is from a hobbyist perspective, but I'm hard pressed to reach for an ATmega for basically anything these days due to the RP2040, the Pico, and its clones.
I do wish there were more ADC channels though. Even an external analog mux costs more than the whole RP2040...
- dheera 2y agoI much prefer the ESP32, the RP2040 doesn't even have WiFi or bluetooth, you would think every microcontroller should have those things these days.

Commercial 16-bit/4ch ADCs can be obtained for <$0.90 in modest quantities. The RP2040 ADC is not good, and I am not often sampling something close to my noisy MCU. I'd rather route I2C anywhere than worry about signal integrity routing my analog signal a mile across the board.
