Features and Benefits

  • Evaluates the MAX1471 Sub-1GHz ISM Receiver
  • Single Input Voltage Supply from 2.4V to 5.5V or Powered from the USB Interface
  • Direct Interface with a MAX32630FTHR Arm® Microcontroller (MCU) Board
  • Available in 315MHz- or 433.92MHz-Optimized Versions
  • Available PMOD Hardware Interface
  • Windows 10-Compatible Software
  • On-Board SPI Interface Control
  • GUI Controls for the MAX32630FTHR Board PMIC Operation from 2.4V to 3.3V
  • Proven 2-Layer PCB Design
  • Fully Assembled and Tested

Product Details

The MAX1471 evaluation kit (EV kit) simplifies evaluation of the MAX1471, a low power, superheterodyne, sub-GHz RF dual-channel receiver designed to receive both amplitude shift keying (ASK) and frequency-shift keying (FSK) data without reconfiguring the device in the 300MHz to 450MHz frequency range.

The MAX1471 evaluation kit operates in conjunction with an external microcontroller (MCU) and graphical user interface (GUI) software running on a computer. The MAX1471 uses an SPI interface for internal register configurations and control.

The MAX1471 EV kit is available in two versions: 315MHz (MAX1471EVKIT-315) and 433.92MHz (MAX1471EVKIT-433). The passive components are optimized for these two frequencies but can easily be changed to work at any RF frequency between 300MHz and 450MHz.

The EV kit includes Windows® 10-compatible software that provides a simple GUI for configuration of the MAX1471 registers through the SPI port. The GUI also controls the on-board PMIC and provides a quick start register configuration to evaluate the MAX1471 functionality, when the MAX32630FTHR applications platform is used.

Applications

  • Automotive Remote Keyless Entry (RKE)
  • Garage Door Openers
  • Home Automation
  • Local Telemetry Systems
  • Medical Systems
  • Security Systems
  • Tire-Pressure Monitoring Systems
  • Wireless Keys
  • Wireless Sensors
