Description:
The ultra-small Mini360 buck step-down voltage regulator is surprisingly powerful for it's size. Synchronous rectification is more efficient and creates less waste heat which allows it to reach current ratings found in regulators many times it's size. Despite the small size and low price, this power regulator delivers on it's specs. The output voltage is adjusted with the on-board potentiometer. Compared to the MP1584, this module offers smaller size, higher operating efficiency, and a higher sustained load rating, but with less pads and tighter input/output voltage ranges. Be careful not to exceed the input voltage or maximum output current. Do not back feed power through the module. Do not apply reverse polarity voltage.
Adjustable non-isolated DC buck voltage regulator, incredibly small module 17x11x3.8mm
Great for LED lights, micro-controllers, battery chargers, and most other low power devices.
Input: 4.75-23V, Output:1.0-17V, 3A Peak / 1.8A Sustained
Efficiency: Up to 96% (depends on the difference between input and output voltage) This module uses synchronous rectification, the most efficient power conversion available.

rotary encoder module
Operating voltage: 5V
Number of pulses: 20
The rotary encoder can count the number of pulses output in the forward and reverse directions by rotation, and the rotation count is not like the potentiometer. This rotation count is not limited. With the key on the rotary encoder, you can reset to the initial state, that is, counting from 0.
working principle:An incremental encoder is a rotary sensor that converts a rotary displacement into a series of digital pulse signals. These pulses are used to control the angular displacement. The conversion of the angular displacement in the Eltra encoder uses the principle of photoelectric scanning. The reading system is based on the rotation of the radial indexing disc (code disc) composed of alternating light transmission windows and opaque windows, and is irradiated vertically by an infrared light source, and the image of the code is projected onto the receiver surface The The receiver is covered with a layer of diffraction grating, which has the same window width as the encoder. The receiver's work is to feel the changes that occur when the disc rotates and then convert the light changes to the corresponding electrical changes. And then the low level signal to a higher level, and produce no interference with the square pulse, which must be used to deal with electronic circuits. The reading system usually uses a differential mode, which compares the two signals with the same waveform but with a phase difference of 180 ° in order to improve the quality and stability of the output signal. The readings are formed on the basis of the difference between the two signals, thus eliminating the interference.

Kit Name: NE555 CD4017 water lamp kit / parts
Supply voltage: 2.5--14.5V
PCB size: 5.4cm * 2.1cm
PCB thickness: 1.6mm
Circuit principle:This kit is mainly composed of a clock generation circuit and a decimal counter circuit. The self-excited multivibrator with the NE555 at its core charges the capacitor C1 through R2, R3 and R4. When C1 just begins to charge, the NE555's 2-pin is still at Low, so the output pin 3 is high, when the power by R2, R3, R4 to C1 charge to 2/3 supply voltage, the output pin 3 level from high to low, NE555 internal discharge tube is turned on , The capacitor C1 is discharged through pin 7 of R4, R3 and NE555 until the voltage at both ends of C1 is less than 1/3 of the supply voltage, and the level of pin 3 of NE555 changes from low to high again. C1 is recharged again, This cycle of oscillation. Charging time: 0.695 (R2 R3 R4) C1, discharge time: 0.695 (R4 R3) C1, adjust R4 can control the output frequency of the oscillator, NE555 clock oscillation signal constantly added to 14 feet CD4017, 10 LEDs are connected to the 10 outputs of the CD4017. When the 10 outputs of the CD4017 are alternately high under the action of the clock signal, D1 - D10 are sequentially turned on to form a water lamp effect.
Adjust R4 to adjust the flow of LED lights.

3, starting power increased from 135W to 170W (3S40A)
Standard version: for starting current below 80A, power 135W below the drill.
Balanced version: suitable for starting current below 80A, power 135W below the drill.
Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!).
Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery 1 Poor battery use effect = 3 poor battery use effect).
Enhanced version:Suitable for electric drill with starting current below 80A and power below 130W .(without balanced function)
Balanced version: Suitable for electric drill with starting current below 80A and power below 170W .(with balanced charging function)
