I can see why the Raspberry might not be a good replacement for Teensy - power hungry (ESP32/STM32 have fantastic ULP/Deep sleep) and/or form factor.

maybe but there are ultra cheap analog and digital multiplexers available.
- mister_hn 6y agoNot only that, also a full bloated OS wasting CPU cycles.
- pugworthy 6y agoExactly. When you want a powerful processor that is going to basically do one thing very well, use a Teensy. When you don't need the power, use Arduino.
- ashtonkem 6y agoRPI straddles the gap between regular computers and embedded systems. It can perform some of the duties of each, but the drawbacks become clearer the further away from the middle ground your use case gets.
- detaro 6y agomultiplexers are fine if you're either doing slow signals or uniform outputs. They're not worth the hassle if you want multiple high-speed connections.
