In the recent Linux Magazine there's an article about the PyPortal from Adafruit
While relatively expensive this product is a very flexible enhancement to your Raspberry Pi, with a touch-screen plus it's own microprocessor, sound output and WiFi connection.
The product's potential can be glimpsed with a quick web search, which will uncover plenty of powerful maker-style projects.
CircuitPython is a variant of the python language specifically aimed at the popular range of maker-style board products from AdaFruit Industries.
Digging under the covers the CircuitPython language is actually a fork of the popular MicroPython language. Consequently when there's a MicroPython update the CircuitPython language is also updated to accommodate any new features and functionality.
However, MicroPython is designed to support a much wider range of boards from many different manufacturers. As a result coding in CircuitPython is going to be a little different in places, so using a MicroPython reference manual isn’t always going to work.
Also note that CircuitPython only has a single file module download to the target board. While his means it isn't as flexible as MicroPython, it does make it considerably simpler to implement and debug.
