XCSOURCE 5PCS IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V TE291
XCSOURCE 5PCS IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V TE291
Description: If you¡¯ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. Bio-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ¡°HV¡± pin, low voltage (3.3V for example) to ¡°LV¡±, and ground from the system to the ¡°GND¡± pin. Dimensions: 0.63 x 0.52" (16.05 x 13.33mm) Package Included: -5PCS 4 Channel IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V

BeElion 2Kits 4PCS Passive PoE Injector and Splitter Kit with 5.5x2.1 mm DC Power Adaptor Connector,Black
BeElion 2Kits 4PCS Passive PoE Injector and Splitter Kit with 5.5x2.1 mm DC Power Adaptor Connector,Black
Features: * 100% brand new; * This kit need the external power adapter to power on the device. Passive PoE Injector and PoE Splitter Kit allows low cost of delivering power over the network cable for shorter distances. * This kit allows power to be carried on 10/100 networks over the spare, unused pairs of a CAT5, CAT5E, CAT6 or CAT7 Ethernet network cable. On shorter network lengths, The power source could feed the wireless access point, IP video surveillance camera,Ip phone etc. * This Kit contains both very cost effective injector and splitter. The injector inserts the DC voltage at the source location into the 5.5mm x 2.1mm injector plug, Then the DC voltage run through the spare pairs of the 10BASE-T or 100BASE-T network cable to the Splitter side, And the splitter splits the DC voltage from the network cable into the 5.5mm x 2.1mm DC jack. Power feed Pins: 4/5(+), 7/8(-) * There are 2 different cables for each color(each color cable you can use respectively). One is used at the router end of the Ethernet cable along with the power supply for the device you want to power. The other one is used at the end of the Ethernet cable to extract the power and send it to the device to power. * Power from POE is generally 24v, most standalone devices is 5v to 12v.This product is used with the 12 volt power supply for that camera(ideal for 12Vdc),Rated Current :1.5Amps. It just adds the power to the Ethernet cable at one end then removes it at the camera end so you can plug it into the camera power connector. If you look at the image you will see one the round connectors on the one pigtail is a male and the other is a female. * If you did not get a 12 volt power supply with the camera you will have to purchase one. It plugs in to a wall outlet and the round plug connects to the POE injector. Package Content: 2Kits 4PCS BeElion PoE injector and splitter cable(Black)
