TinyScreen+ Processor Board

TinyScreen+ is TinyCircuits' second generation processor board based on the popular TinyScreen shield with an added Atmel SAMD21 32-bit ARM® processor, USB port, power management, and Microchip MCP73831 battery charger. The powerful Arduino Zero compatible board offers an OLED development system in a one square inch design. The board has the standard TinyShield expansion port, allowing for use of all the current TinyShield expansion boards and all 20 IO pins are available for use since the onboard OLED and four buttons are directly connected to extra hardware on the processor. The OLED is a brilliant 16-bit color 96x64 pixel display capable of up to 40 FPS 16-bit color video playback from a microSD card, with single channel line-level audio output.

TinyScreen+ uses the same TinyScreen library inside the Arduino programming environment, and most TinyScreen code and Arduino libraries will work as they are. New users can get started with just the TinyScreen+, a micro USB cable, and a computer and current users with TinyScreen code can run most existing code on the TinyScreen+ with only minor code changes.
