Embedded Artists, NXP Team on ARM-based Android Open Accessory Development Kit

Embedded Artists and NXP Semiconductors teamed on a new Android Open Accessory Application (AOAA) development kit. The AOAA Kit for Android includes the NXP LPC1769 and the LPC11C24 microcontrollers, which are based on the 32-bit ARM Cortex-M architecture. The board in the kit features a remote CAN node and interfaces for Ethernet, CAN and IEEE 802.15.4. The AOAA Kit for Android makes it easy for designers to develop, evaluate and prototype more complex accessories for Android smartphones and tablets. It is available now for $79.99.

The Embedded Artists AOAA kit includes reference applications to test and build Ethernet, CAN and wireless functions. The royalty-free reference applications for controlling and monitoring the AOAA board from an Android device; using the Android device to detect, control and monitor CAN nodes in a CAN network; and using the Android device to detect, control and monitor Xbee nodes.
