20Pcs 8-Channel Logic Level Translator Converter Bi-Directional Module Introduction: If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-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. Feature: 8-channel high-voltage and low-voltage logic bidirectional translation Mini size, 4.1cm x 1.8cm Comes with 2 rows of 6pin, unsoldered Compatible breadboard, can be directly inserted in the breadboard Note: (For example: High voltage: 5V, low voltage: 3.3V) HV connect 5V power supply LV connect 3.3V power supply GND connect negative, two power supply commons LVx input and output is 3.3V TTL, HVx input and output is 5V TTL, LVx and TVx bidirectional transfers Package includes: 20 x Eight Channel Logic Level Translator Converter

20Pcs ND 2/4/8/16 Filter Kit Holder Wide Adapter Lens Hood LF292 For Cokin P Description: In photography, filter have the effect of "dressing".If you can use the filter flexible, it will help you improve the performance of photography, and can change the scene of the tone, make the photos more close to nature. So it is popular with photographers alike. And gradual filter is a MUST for digital users, because the digital sensor unlike film has very low exposure tolerance. Detail will be lost on both low and high light area. To correct this, you need gradual filter to balance it! Features: Control light and colour directly on your raw images at the time of shooting, Keep the quality of your images without excessive post production work,save your time. Same filter for all your lenses by just replacing the adaptor ring. Weight: 355g Fitment: Cokin P series For 8pcs Cokin ND Filter Set(Third Party) Compatible with Cokin P series. To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations. To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas, etc. To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
