LPC54114 Audio and Voice Recognition Kit

The LPC54114 Audio and Voice Recognition Kit provides a complete hardware and software platform for developers to evaluate and prototype with the LPC54114 processor family. It has been developed by NXP to provide all that you need to develop an always-on low power voice triggering product.

LPCXpresso™ is a low-cost development platform available from NXP, supporting NXP's ARM-based microcontrollers. The platform is comprised of a simplified Eclipse-based IDE and low-cost target boards which include an attached JTAG debugger. LPCXpresso is an end-to-end solution enabling embedded engineers to develop their applications from initial evaluation to final production.
