I have a few of these, well, will have a few more over next week...

I am tweaking the design but all of them do 2A 3.3V power for many peripherals, and ALL the GPIOs for an ESP32-S3-MINI-1-N4-R2, and a single WS2812 LED.

USB-C and DC 5V-17V

They are ideal for anyone wanting to play around with these processors, whether native ESP IDF, #micropython, #arduino, or whatever.

This prototype cycle for my temperature and humidity tracker is almost complete with a new 50% slimmer case. It's been quite a journey #electronics #kicad #esp32 #micropython #blender #3dprinting

The July Melbourne #MicroPython Meetup is on tonight! Sean has hosting duties and will be delivering the News Roundup. Hope to see you there (or online)!

For those not following #m68kMicroPython development, a lot has been happening rather quickly in the last couple of weeks!

There's enough support for the Toolbox now that I've been able to re-create the #Macstodon splash/loading screen with it - see below.

Big thanks to @stylus for all his hard work developing the port and making this possible!

I made a new release of m68k-micropython: https://github.com/m68k-micropython/micropython/releases/tag/20250720

This adds the following groups of mac APIs (which I didn't actually test):

• deskmgr
• dialogmgr
• fontmgr
• menumgr
• textedit

#m68kMicroPython happenings: The "struct-types" branch is coming along. There are now autogenerated bindings for the following parts of the API: modmactypes.c
modqd.c
modtoolboxevent.c
modtoolboxutil.c
modwindowmgr.c

there's probably broken stuff but for instance you can now splat directly onto the screen

>>> scrn = qd.qdGlobals().screenBits
>>> n = scrn.bounds.bottom * scrn.rowBytes
>>> for i in range(n): scrn.baseAddr[i] = i

and types are checked:

>>> qd.FillRect(7, "blue")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Expected int, got Rect

um well except the error message is backwards

and in upstream #micropython land my exploration found that there were problems with the uctypes module and "REPR_B", so I'm working on fixing that and ensuring it stays fixed via the CI system: https://github.com/micropython/micropython/pull/17688

right at the moment, the micropython PR is failing for some reason that will probably be more obvious to me once I've had another night to recover from jet lag.

Why Lua Beats MicroPython for Serious Embedded Devs

｢ Lua isn’t just compatible with embedded systems; the Lua ANSI C library was designed for them. Its architecture is clean, compact, and deterministic.

MicroPython, on the other hand, is a reimplementation of Python 3. It works well for many embedded use cases, but it inherits assumptions from a desktop-oriented language ｣

It's teacher Tuesday!!

If you're teaching with or learning Raspberry Pi Pico programming using #MicroPython I've just shared five introductory programming activities for BEAPER Pico that you can easily adapt to other circuits!
