Would a pyboard purchase support the project?

I really appreciate MicroPython and would like to support the project. However, having chosen the ESP32 platform, I do not need to purchase a pboard or accessory at this time. How about adding a "Donate" item to the official store? This would give people such as myself a way to contribute. It would be nice if a short message could be sent with the donation, possibly to indicate a (non-binding) preference for what the donation is to be used for.

Pyboard D has many advantages with respect to ESP32, so it is worth to have at least 1 or 2 Pyboard D + accessories to compare with other microcontrollers (ESP8266, ESP32, etc).

A "Donation button" is also ok.

I was also interested and found this; https://github.com/boochow/micropython-raspberrypi/

Looking a the ref; https://github.com/boochow/micropython- ... icroPython

It looks like the pi zero would have a very different use case to the Pyboard. No ADCs or DACs is a problem for me, for instance.

Bare metal ports are generally much faster. Interrupt latency might be ~10μs rather than ~800μs. Most OS's have a pre-emptive scheduler which grabs chunks of time at will, so program execution is not deterministic. This matters in some applications.

You can get breakout boards with converters. But I'd go for a Pyboard in preference if I needed them.
