TinyScreen+ (Processor, OLED & USB in One)

TinyScreen+ is TinyCircuits' second-generation processor board. We took our popular TinyScreen shield and added an Atmel SAMD21 32-bit ARM processor (the same one used in the Arduino Zero), USB port, power management and battery charger - what you get is a powerful OLED development system in one square inch.

We've kept our standard TinyShield expansion port, allowing for use of all of our current shields, and all 20 IO pins are available for use- the onboard OLED and four buttons are directly connected to extra hardware on the processor.

The OLED is the same brilliant 16-bit colour 96x64 pixel display, now capable of up to 40 FPS 16-bit colour 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. Note: The battery is not included and is sold separately.

Notes

• New users can get started with just the TinyScreen+, a micro USB cable, and a computer
• Current users with TinyScreen code can run most existing code with minor changes
• To send text to the Arduino IDE Serial Monitor, use the SerialUSB object instead of Serial
• All batteries are sold separately
