Arduino Uno R3 CH340G ATMega328P Development Board Compatible with Arduino
[Arduino Boards, Development Board] Product Description The Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 USB to Serial converter chip, instead of using an Atmega16U2 chip. We have used plenty of these low-cost Arduino boards with CH340 chips, and have found them to work perfectly. The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation, this board is identical to the more expensive version without CH340 chip. Features The Arduino Uno R3 is a micro-controller board base on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs); 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything need to support the micro-controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get start. The Arduino Uno R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) program as a USB-to-serial converter. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Note: The Arduino Uno R3 reference design can use an Atmega8, 168, or 328, Current models use an ATmega328, but an Atmega8 is shown in the schematic for reference. The pin configuration is identical on all three processors. Package Includes 1 x Arduino Uno R3 CH340G ATMega328P Development Board

Water Cooling Head Water Cooling Plate 40*40mm
[Aluminium Heat Sink] 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 pump is required, and typically small DC magnetic-drive pumps are used to minimize the amount of pump power (heat) that is imparted to the fluid. Applications: Computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling. Features: Heavy Aluminium build Internal flow channel extrusion forming Applicable to computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling Package Includes: 1 x Water Cooling Head Water Cooling Plate 40*40mm
Out of stockTEC1 12706 40x40mm Thermoelectric Cooler 6A Peltier Module
[Thermoelectric Peltier Module] Looking to cool down your DIY project or any electronic device then you are at the right product. The TEC1 12706 40×40 mm Thermoelectric Cooler 6A Peltier Module is the simple application of the Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 40 x 40mm which very effectively cools and heats up to 90°C. The thermoelectric cooler is also known as TEC or Peltier Module creates a temperature differential on each side. One side gets hot and the other side gets cool. They use to either warm something up or cool something down; above all, you can use either side. You can also take advantage of a temperature differential to generate electricity. A thermoelectric cooler (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely useful in industrial areas, for example, computer CPUs, CCDs, portable refrigerators, medical instruments, and so on. Operating Tips: Max. Operating Temperature: 138 Degree C Do not exceed Imax or Vmax when operating a module. Please carry out moisture protection options (sealing) in final application use. Life expectancy: 200,000 hours Failure rate based on longtime testings: 0.2%. Connection Diagram of TEC1 12706 with Arduino: Features : Small module. Operable up to 138°C. Easy transition between the hot side to the cool side and vice-versa just by reversing the polarity of the supply. Quality tested cooling cells. Solid-state, vibration-free, noise-free. Simple to install and operate. Should use with a heat sink. Package Includes: 1 x TEC1 12706 Thermoelectric Cooler cooler 12 Volt 92 Watt.
