Developers, makers and Arduino enthusiasts that are looking for a small smart display may be interested in a new piece of hardware called the Pixel 2.0. Which combines a 32-bit 48MHz ARM Cortex M0+ micro-controller together with a colour OLED display and handy MicroSD card reader in one tiny package.
The Pixel is an Arduino Zero compatible a smart display but is now available to back with pledges starting from just $75 and worldwide delivery expected to take place during June 2017.
Watch the promotional video below to learn more about the inspiration, features and design of the new Pixel 2.0 smart display created by Rabid Prototypes.
Specifications of the Pixel 2.0 include :
• Microcontroller: Atmel ATSAMD21G18 ARM Cortex M0+
• Clock speed: 48 MHz
• Operating voltage: 3.3V
• I/O pin limits: 3.3V, 7 mA
• Digital I/O pins: 14, with 12 PWM
• Analog input pins: 6, 12-bit ADC channels
• Analog output pins: 1, 10-bit DAC
• Flash memory: 256 KB
• SRAM: 32 KB
• Voltage regulator: 3.7V – 5.5V input / 3.3V, 300mA output
• PCB Dimensions: 1.8 x 1.8″ (46mm x 46mm)
• Display : 128×128 16-bit color 1.5″ (38mm) OLED w/ SSD1351 driver
Programming is easy! Like most Arduinos, you simply plug the board into your PC using a MicroUSB cable, select the board you want to program, and hit the upload button in the IDE when you’re ready. The Pixel ships with the Arduino/Genuino Zero bootloader installed.
The Pixel is compatible with the Arduino’s SPI and SD libraries. Communication with the display and MicroSD card are both handled through the SPI bus, which is broken out on a set of pads for a surface mount header. The ATN pin replaces the reset pin on this header and acts as the CS pin for the MicroSD. Pins 7, 8, and 9 (ORST, ODC, OCS) are also utilized to control the display.
