Starling is a modular, Open Source LED display with WiFi connectivity. It comes with a mobile app for easy configuration and usage and has hardware support for Bluetooth.
The LED matrix is driven by an Atmega8 microcontroller (MCU), instead of a standard ASIC. This provides a lot of flexibility in the firmware. The firmware detects and assigns IDs to newly plugged-in modules. The microcontroller also stores font tables; hence if ASCII is sent on the serial (UART) port of the MCU, ASCII is what will be displayed on the matrix. Since the firmware detects adjacent displays, it can easily decide if it needs to display static or scrolling text.
