NXT FRDM-K64F Single Board Computer (SBC)
The NXP FRDM-K64F SBC is the host development and operational platform (the controller).
The elements used by the IoT Kit are as follows:
–
MK64FN1M0VLL12 MCU (120 MHz, 1 MB flash memory, 256
KB RAM, USB) which is based on a Cortex M4 ARM processor
core
–
RGB LED
–
The OpenSDAv2 debug circuit supporting the CMSIS-DAP
Interface to allow programming and monitoring software
–
Serial port interface
–
I2C interface for communicating with off-board sensors
–
UART interface for communicating with the WNC-Shield card
WNC-Shield Board
Avnet has produced an Arduino Shield with a Wistron NeWeb
Corporation (WNC) M14A2A cellular module. This module
contains all necessary protocol stack functionality needed to
establish and maintain a data connection in an LTE network.
The WNC cellular module is controlled/managed via AT
commands exchanged using a serial port connection to the
FRDM-K64F. This is referred by WNC as a Type III interface
to allow
support for the 3GPP defined AT commands plus
proprietary AT commands.
The block diagram for the WNC-Shield is shown below:
