4Tronix Angle:Bit - Turn your BBC Micro:Bit by 90 Degrees (AngleBit for MicroBit)
This great little adaptor lets you change the oritentation of your BBC micro:bit from horizontal to vertical, or vice versa.
As an added bonus, the edge connector is wired so that you can insert the micro:bit either way round so you can decide whether you want the LEDs facing forwards or backwards (or up or down).
The design is very compact so it can fit in most accessories. It is particularly useful for Bit:Bot as it allows the micro:bit to be accessed easily even when the ultrasonic sensor is fitted.
