$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]
