Bluetooth Wireless Communication

Fully qualified Bluetooth low energy stack, allowing the board to communicate with a wide range of Bluetooth devices, including smartphones and tablets

Tact momentary push buttons

Six tact momentary push buttons located on the front of the board and debounced by software, which also includes short press and long press detection. 1 additional push button on the back connected to the STM32WB55 processor for system reset purposes

Circular Color IPS TFT display

Circular Color IPS TFT display for high-resolution text and graphics, connected to the application processor. Runtime software repeatedly refreshing the screen at a high speed, such that it is within the user persistence of vision range, and no flicker is detected

Motion
sensor

Combined accelerometer and magnetometer chip providing 3-axis sensing and magnetic field strength sensing. Board gesture detection (such as fall detection) in hardware, and additional gesture sensing (e.g. logo-up, logo-down, shake) via software algorithms

Power
Supply

Provided via the USB connection, via the interface chip (which has an on-board regulator), or via a battery plugged into the top connector

USB
Communications

On-board USB communications stack built into the firmware of the bootloader and providing the ability to drag and drop files onto the mass storage drive to load code into the application processor. Serial data streamed to and from the application processor over USB to an external host computer

Jacdac and micro:bit connection

2 Jacdac connectors as well as a Micro:bit connector to connect a Jacdac hub in order to wire a larger number of sensors. Plug-and-play system for cascading sensors/actuators on the fly through which the devices are automatically recognised and the associated services can be added at any time
