The FRDM-KV10Z hardware is form-factor compatible with the Arduino R3 pin layout, providing a broad range of expansion board options. Board embeds a 6-axis digital sensor, combining accelerometer and magnetometer, an analog thermistor, a RGB LED and two user push-buttons. The FRDMKV11Z platform includes the OpenSDA, the NXP open-source hardware for embedded serial and debug adapter, programmed with an open-source bootloader. This circuit offers several options for serial communication, flash programming, and run-control 2016 NXP B.V. PRELIMINARY FRDM-KV11Z Hardware Overview debugging. OpenSDA software is from P&E Micro debug interface firmware for rapid prototyping and product development. 2. FRDM-KV11Z Hardware Overview The features of the FRDM-KV11Z hardware are as follows: MKV11Z128VLF7P MCU (75 MHz with hardware square root and divide, 128 KB flash and 16 KB RAM memory, dual 16-bit ADCs and motor control timers, CAN, 48 LQFP package). Triple role USB interface with micro-B USB connector RGB LED FXOS8700CQ Accelerometer and magnetometer Two user push buttons Flexible power supply option OpenSDA USB, and Arduino header and 5 V power input Easy access to MCU I/Os through Arduino R3-compatible and proprietary headers Programmable OpenSDAv2.1 debug circuit programmed with the CMSIS-DAP Interface application that provides: o Mass storage device (MSD) flash programming, over a driver free USB connection. o P&E Micro debug interface providing run-control debugging for ARM IDE toolchains. o Virtual serial port interface.
