If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. This logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4...
This is a simple to use DC-DC step-up circuit. Use it to boost a lower voltage to an higher one. This circuit boasts a passive cooling system allowing you to power high power systems (led matrixes or motors for example).
Energy Shield is a LiPo battery based power shield that keeps your project alive. It keeps its battery charged whenever an available power source exists. It accepts a wide range of power sources, from common solar cells via JST connector and USB via USB port on microcontroller, to 9V and 12V DC adapters via DC Jack on your Arduino. Meanwhile it can not...
The Wireless Charging Module can be applied in electronic equipments in common use for close wireless charging or power supply. Consisted of a transmitter and insulation coil, it could serve as a replacement for the Wireless Power Supply with stable 5V output voltage and maximum 600mA output current. Its small size and insulation coil is more suitable for...
