Power Bank Module is a super mini power bank mainboard compatible with 3.7V-4.2V li-ion battery. On-board micro USB port for battery charging and USB type A female output port supporting DC 5V A input and 5V 2A output. Just connect it with a 18650 battery then you can get a portable power bank.
Liquid coolers excel at delivering cooling to concentrated heat sources such as Peltier Elements and for delivering cooled fluid into remote or compact locations where the cooling assembly itself cannot be located. The basic operation is simple: fluid flows in one tube, it is cooled, and then it flows out the other tube. An external…
The OV7670 CAMERACHIPTM is a low voltage CMOS image sensor with the capability of a single-chip VGA camera and image processor in a compact footprint device. The OV7670 captures full-frame, sub-sampled, or windowed 8-bit pictures in a variety of formats using the Serial Camera Control Bus (SCCB) interface. This device contains an image array that…
