描述

Today’s cars are equipped with many remote units used for radio and global positioning antennas and remote cameras and microphones. Quite often those remote units are supplied by the head unit through cables that require a regulated and protected power supply source. The MAXREFDES175 reference design shows how to implement eight phantom power supplies and how to take advantage of the numerous diagnostic features offered by the MAX20084 using the BeagleBone® Black platform.

Design files, firmware, and software can be found on the Design Resources tab. The board is also available for purchase.

优势和特点

  • Eight automotive phantom power supplies
  • I2C programmability and diagnostic
  • Portable software driver

详情

To test the cape, a simple run.sh script is included and builds the software using a GNU to make and launch the example software.

Required Equipment:

  • BeagleBone Black with Debian® OS
  • 12V/1A power supply
  • MAXREFDES175 BeagleBone cape
  1. Plug the BeagleBone cape on top of the BeagleBone Black board.
  2. Connect a 12V/1A supply between the GND and VBATT test points of the MAXREFDES175#. Alternately, plug a 12V/1A wall power supply into the standard J1 connector of the MAXREFDES175.
  3. Log in to the BeagleBone Black.
  4. Unzip the MAXREFDES175_SW.zip file and copy the MAXREFDES175_SW folder into the BeagleBone Black.
  5. Navigate to the MAXREFDES175_SW folder and type ./run.sh.
