TEC1-12710 Thermoelectric Cooler Peltier Element Module

Number of component pairs: 127
Assembly pressure: 85N/cm2
Be sure to apply thermal grease when installing the radiator
The literal is cold side, and the non-literal is hot side
Packaging process: standard 704 silicone rubber seal around
Packaging standard: foam box packaging, storage conditions ambient temperature -10 ~ 40 degrees Celsius
Working environment: temperature range -5583 degrees Celsius (excessive ambient temperature will directly affect the cooling efficiency)
The working state of the cooling plate is that one side is cooling and the other side is heating, and the heating surface must be well dissipated during work. It is strictly forbidden to energize for more than 2 seconds without heat dissipation, so as to avoid overheating and burning.

VU Meter Driver Board Module Adjusts Power Amplifier (TS-VU003)

AC/DC12-16V power supply, distinguish between AC and DC input terminals. L, G, R: These are the dual-channel input terminals of the driver board, which can be connected to the audio of mobile phones, computer sound cards, preamplifiers and other audio source devices (the signal is the signal that the headphones can hear), and the amplifier output terminal to get the signal. When wiring, L, G, and R correspond to the left, ground, and right channels of the audio source device respectively. If the input is a mobile phone, computer sound card, preamplifier and other audio sources, please turn the dip switches 1 and 3 to the ON end. 1.

10 PCS KY-040 360 Degree Rotary Encoder Module

Material: Electronic components + PCB
Working voltage: 5V
Number of pulses per revolution: 20
The rotary encoder can count the number of output pulses during rotation in the forward and reverse directions by rotation. Unlike the potentiometer, the rotation count is unlimited. With the buttons on the rotary encoder, it can be reset to the initial state, that is, counting from 0.
Working principle: The incremental encoder is a rotary sensor that converts the rotational displacement into a series of digital pulse signals. These pulses are used to control angular displacement. The conversion of angular displacement in the Eltra encoder uses the photoelectric scanning principle. The reading system is based on the rotation of the radial index disc (code disc) composed of alternating light-transmitting windows and opaque windows, and is simultaneously illuminated vertically by an infrared light source, and the light projects the image of the code disc onto the surface of the receiver . The receiver is covered with a layer of diffraction grating, which has the same window width as the code wheel. The receiver's job is to feel the changes produced by the rotation of the disc, and then convert the light changes into corresponding electrical changes. Then the low-level signal is raised to a higher level, and a square pulse without any interference is generated, which must be handled by an electronic circuit. The reading system usually uses a differential method, that is, comparing two different signals with the same waveform but a phase difference of 180 in order to improve the quality and stability of the output signal. The reading is formed based on the difference between the two signals, thereby eliminating interference.
