Genuinely curious, what kinds of projects are better suited to a Teensy than an Arduino, ESP32 or some form of Raspberry Pi? Is the main advantage the pin count?

Ah - we asked the same question: https://news.ycombinator.com/item?id=23144432

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.

I've been playing around with boards like this that keep getting smaller and smaller. Do people generally prototype something using these boards and then go directly to manufacturing? I imagine you'd want to have a smaller package than use these types of components as part of you larger product right?

No, it would be performance - for example regarding clock speed and RAM size.

Just out of curiosity, what could be a use case for this thingy?

Their blog (when it loads) gives some great examples: https://www.pjrc.com/blog/

many synth kits use a teensy or a similar board for their CPU so that the builders don't need to do the SMD soldering but can still use high speed CPUs

> better suited to a Teensy than an Arduino

In my experience, all projects I would do with an Arduino. Thus far, it's just been LED stuff. On Arduino I very quickly ran out of resources, then had to redo my entire project wiring to switch over to a Teensy.

Not only that, also a full bloated OS wasting CPU cycles.

I've used the Teensy 3.1 and it's more or less an Arduino (including uses the Arduino IDE) but lower cost and more powerful processor. There is also a way to build C/C++ code and run it on the Teensy. ESP is similar but has WiFi built in and Raspberry Pi is closer to a full blown general-purpose computer than an embedded platform. Software on the Teensy runs on bare metal, software on the Raspberry Pi usually runs on an operating system (Linux) and is not real-time.
