Nevil Hunt demoed a nifty system to connect boards like Adafruit’s displays and sensor breakouts to the BBC micro:bit.  The zbit:connect system uses simple screw and bolt connections to attach boards and send power & data.  This is great for quickly swapping out devices without soldering or even stacking boards for a compact project build.  This looks great for using with MicroPython on the BBC micro:bit too!   Nevil writes:

‘zbit:connect’ is a range of add-on boards for the BBC micro:bit developed by innovations in education which use a unique custom connector system allowing multiple boards to be simply ‘bolted’ onto the micro:bit allowing additional boards to be connected in the X, Y and Z direction thus enhancing and expanding the micro:bit’s educational possibilities!

Auxiliary connectors on these boards make it easy to add a vast range of 3rd party Sensors, Displays and Wireless Interface boards. The ‘zbit:connect multi display board’ demonstrates 5 Adafruit display boards and 2 Adafruit sensor boards controlled by a micro:bit with software written in Micro Python, connected by a number of zbit:builder and zbit:toolbelt boards and powered by zbit:power.

 
The ‘zbit:connect’ range is still in development but will be demonstrated at the IoT Tech Expo Global 2017 at Olympia, London 23rd – 24th January.
