Arduino users may be interested in a new mini OLED display created by Rabid Prototypes which combines a 32-bit 48MHz ARM Cortex M0+ micro-controller complete with colour OLED display and MicroSD card reader.
The Pixel Mini is now available to back with pledges starting from $45 and shipping expected to take place during October 2017 allowing you to create wearables, create games or attach sensors and display data on screen using text or graphics.
Specifications include :
• Microcontroller: Atmel ATSAMD21E17A ARM Cortex M0+
• Clock speed: 48 MHz
• Operating voltage: 3.3V
• I/O pin limits: 3.3V, 7 mA
• Digital I/O pins: 12 (10 w/ PWM) + 2 I2C pins
• Analog input pins: 3, 12-bit ADC channels
• Analog output pins: 1, 10-bit DAC
• Flash memory: 128 KB
• SRAM: 16 KB
• Voltage regulator: TLV702 (3.7V – 5.5V in / 3.3V, 300mA out)
• PCB Dimensions: 1.3 x 1.3″ (33mm x 33mm)
• Display : 96×64 16-bit color 0.95″ (24mm) OLED w/ SSD1331 driver
Programming is easy! Like most Arduinos, you simply connect the board to your PC or Mac with a MicroUSB cable, select the board you want to program from the menu, and hit the upload button in the IDE when you’re ready! Unlike the original Pixel however, the Mini requires the Rabid Prototypes Tau board definition files, so you will want to install those first!
The Pixel Mini 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 can be accessed via pins 11-13. Pin 10 (SS) acts as the chip select pin for the MicroSD, and pins 5, 8, and 9 (ORST, ODC, OCS) are used to control the display.
