This is battery level display module based on battery style digital tube LED. The 5 - segment LED inside is red light and the frame is green light. There is driver chip TM1651 onboard, so the control interface is simple, just two signal lines and VCC / GND. It can be used to display the battery power.
Instantly convert any plug into a connected and intelligent outlet with a convenient timer function that works both on your smart phone and has a manual control knob. Perfect for lighting and other appliance with pre-set ON/Off functions. Control devices from anywhere
Comme les LiPo Rider ce module permet de charger vos batteries à partir d'une source 5v (usb par exemple) tout en sortant un 5v constant pour vos applications. Il se branche directement sur une batterie Lithium Polymer ou Lithium Ion.
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...
Ce module de charge sans contact peut etre utilisé pour transmettre de l'énergie entre deux objets proches. Il est constité d'un emetteur et d'un récepteur avec des bobines de transmission. Il fournit un voltage constant de 5v en 600mA. Sa taille réduite et ses bobines isolées en font un partenaire idéal de vos projets sans fil.
In our application, especially in some outdoor applications, we often need to use the lithium battery, lithium battery charging problem is a need to solve the problem, we designed this mini lithium battery charging board.
Board size is very small , It can use external power supply, such as solar or USB power supply. It uses CN3065 - a single lithium...
