Micro:Bit Expansion Tray

This Micro:Bit Expansion Tray is a compact workspace for organizing your BBC Micro:Bit, an IO Expansion Board, an 82×54 mm breadboard, and a 9V battery.
The Micro:Bit slot is press-fit, keeping the board secure while still easy to remove. A small pocket gives access to the USB port and doubles as storage for small components.

The tray includes a recessed area for a breadboard (you may need to trim off the side link tabs) and a compartment for a 9V 6LR61 battery.
On the underside, modular grooves allow stacking or attaching add-ons like extra trays or a jumper-wire holder.

An optional 45-degree stand is included for better visibility while working. It can be used with this tray or as a universal stand for other projects.
