This is a product idea I've been prototyping. In SPI mode, it's a breakout board for the Sharp Memory LCD (160x68, 1.1") with a built-in 50% duty cycle oscillator (needed by the LCD as an external component), and runs at about 55uA. In SSD1306 emulator mode it presents a normaly I2C interface and uses between 1 and 2 mA. Viable product or oddball idea?
