Description

The SecureIoT1702 Development Board is intended as a development, demonstration, and testing platform for Internet-of-Things applications using the CEC1702, a 32-bit ARM® Cortex®-M4-based microcontroller with additional security peripherals. The board features a variety of hardware options (including a power supply, user interface, serial communications, and expansion headers) that enable rapid prototyping and development of embedded, secure Internet-of-Things applications. In addition to the native hardware features provided by the SecureIoT1702, hardware expansion is possible through the use of mikroBUS™ accessory boards.

Features

  • USB micro-B connector - Provides power to the board and provides an interfacefor serial input/output using the FT230X Serial-to-USB converter.
  • 10 kΩ Potentiometer – useful as an analog signal source for ADC demonstrationor user interface purposes.
  • Analog-to-Digital Converter expansion header – provides an expansion headerfor variable-resistance circuit elements, such as a thermistor.
  • 32.768 kHz crystal oscillator – provides an external high-precision clock sourceon the CEC1702’s XTAL1/2 oscillator input pins.
  • SST26VF032B Serial Flash – Stores the program image for the CEC1702 andprovides additional persistent storage for application information.
  • Serial Flash programming header
  • Color LED – Full color PWM-driven LED.
  • Status Indication LED – Output LED for the CEC1702’s Blinking/Breathing LEDhardware module.
  • LED Output Header – Expansion header for the second CEC1702 Blinking/Breathing LED hardware module.
  • JTAG Debugging Header
  • I2C Expansion Header
  • 128x64 pixel LCD – EastRising ERC12864 SPI-interface LCD. Useful for displayinguser application text/images.
  • 8x general-purpose pushbuttons – provides user input. Readable by theCEC1702’s hardware keyscan module or by general-purpose I/O input.
  • 2x mikroBUS™ Interfaces – useful for attaching a wide array of hardware expansionboards to extend the functionality of the platform.
