Board size: 2.5*3.5cm
Buzzer: 5V passive buzzer, the sound of tap-tap-tap is small, please carefully if you mind!!
Function Introduction:
After power on, NE555 outputs a certain frequency of square wave pulse. The high level lights one lamp and the low level lights the other lamp, so the two LEDS flash alternately and there is a clicking sound.
This kit needs to be welded and installed by the buyer himself.
 
 
Circuit introduction:
The core component of this circuit is the 555 integrated timer, which works in the non-steady mode. After the power is switched on, the 3pin level at the output end of the 555 integrated timer constantly changes its high and low level. When the 3pin is at high level, LED1 goes out and LED2 shines.
When the 3 feet are low, LED1 shines and LED2 goes out. At the same time, capacitor C3 discharges through the loudspeaker, and the loudspeaker makes a "tap" sound.
So the leds light up alternately, and the speakers make a tap-tap-tapping sound.

MAX4466
 
Description: Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task!
The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!
This breakout is best used for projects such as voice changers, o recordingmpling, and o-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x.
That's down to be about 200mVpp (for normal speaking volume about 6 inch away) which is good for attaching to something that expects'line level'input without clipping, or up to about 1Vpp, perfect for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!
Using it is simple:
Connect GND to ground, VCC to 2.4-5VDC.
For the best performance, use the "quietest" supply available (on an for Arduino, this would be the 3.3V supply).
The o waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its
perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the o equipment you're using requires AC coupled o, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an o amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an o amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin.
For o-reactive projects, we suggest using an FFT driver library which can take the o input and'translate'it into frequencies.

Product Introduction:
1.Operating Voltage: 5V
2.Pulse Number for One Circle: 20
3.Rotary encoder can count the output pulse times by rotating positively and negatively. This counting method has no limitation, it can reset and come back to the  initial status if matching with the key on the encoder (that is to say it will count from 0)
4.Operating Principle: Incremental encoder is a kind of rotary sensor which transforms the rotation displacement into a series of digital pulse signal. These pulses are used to control angular displacement. In Eltra encoder, the transformation of angular displacement adopts photoelectric scaning principle. The reading system is based on the radial dividing plate's rotation of alternative light window and non-light window, and it will be exposed to infrared light source at the same time. The light will reflect the picture of plate on the surface of receiver. The receiver is covered by a diffraction grating, and it has the same window width with the plate. The operation of receiver is to detect the change of light plate rotation, then transform the light change into electric change. Increase the low level signal into high level and generate square pulse without any interference. This process needs circuit to deal with. The reading system usually adopts differential method, that is compare two different signals who have the same waveform bu the phase difference is 180 degree so as to improve the output signal quality and stability. Reading is formed on the basis of the difference between two signals, so it eliminates the interference.

The balance board is suitable for  the li-ion battery pack BMS WHICH without  balance function,so as to  equalizing charge lithium battery charge function, make the battery pack each series charge at the same time.
 
Note:The balancing board must need BMS to use together,and the BMS is without balancing function
 
Parameter:
Balance Voltage for each single cell: 4.2V
Balance current for each single cell :66mA
Size: L25mm*W22mm
Balancer is just a Auxiliary function, The balancing means when the battery charging,each series battery need with the same voltage.when ONE cell voltage get 4.2V ,the other cells not, the first cell voltage will discharge to wait the other cells rising to the same level.
 
Note:
battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma
 
Cut-off  Voltage is according to the BMS setting.
 
Note:the balancer starts balancing when the one cell get 4.2V, The Cut-off  Voltage is according to the BMS setting,but the bms cut-off voltage needs more than 4.25V which is much better.

2.Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor, the length of the antenna 433M of about 17cm;
3.Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
