OM13069UL (NXP)

The OM13069 Smartphone Quick-Jack solution includes a small PCB with an LPC812 microcontroller, an energy harvesting IC, a miniature joystick and an expansion header. The LPC812 is an ARM, Cortex-M0+ microcontroller which manage the data transport, encoding/decoding data using the Manchester algorithm to be exchanged over the audio channels. The board's expansion header makes it easy connect myriad sensors (such as temperature, humidity, wind, heart rate, accelerometer etc), switches (lights, power etc), HMI devices (such as keyboards, game controllers etc) or other devices that collect or log data from a variety of sources. An energy harvesting circuit utilizes the right audio channel to draw power from the smart device to power the Quick-Jack board and attached sensors. The onboard joystick can be used to demonstrate a UI implementation and results are displayed by an App on the connected smartphone or tablet.
