Use this tiny and convenient module to power your JeVois smart camera from your car battery or any other power source 6V to 24V voltage.

Note: This accessory is intended for applications where you will not stream video out of your JeVois camera to a host computer, but instead will only stream text outputs over serial port to an Arduino. Hence, the mini-USB port of your JeVois smart camera will only be used to power the smart camera. Please see http://jevois.org/doc/UserConnect.html for more information.

Product Features:

  • Max output current 3A (peak), 2.1A (sustained), powerful enough to power your JeVois smart camera (which uses 0.7A max).
  • New design, 3 solid-state ceramic capacitors (MCC), safer and low ripple currents.
  • Synchronous rectification, high efficiency, 6.5V to 5V 0.7A can achieve up to 97.5 efficiency%, 12V to 5V 1A up to 94% efficiency.
  • Flat copper inductor, improves conversion efficiency.
  • With output overvoltage protection. There is a 1.5A fuse on board, output 5V have 300W TVS tube to protect your USB device.
  • Using the latest USB identification circuit, perfectly compatible with JeVois, and also can be used to charge your iPhone, most Android phones, iPad, etc.
  • High quality USB connector.
  • Output voltage indicator (RED led).
  • Small size, 26.4 (L) * 15 (W) * 7.4 (H) mm.
  • Input with reverse polarity protection diode, will not be damaged when input is connected incorrectly.
  • Ultra-low static current, 0.85 mA only. You may in most cases not need to add a switch when connecting to a car battery, can be connected to car cigarette lighter cable or ACC power supply cable.

Module Parameters:

  • Module Properties: non-isolated buck module (BUCK) synchronous rectification
  • Input voltage: DC 6-24V
  • Output voltage: 5.1-5.2V
  • Output current: 3A MAX (please enhance heat dissipation is using at full load, e.g., add a fan). Actual test result with input 12V and output current 2A does not need enhanced heat dissipation.
