Description
Supply voltage：5V-16V
Continuous current: 10A
Short maximum current: 20A (less than 10 seconds)
Speed control mode: PWM stepless speed regulation, can also be used to adjust the light
Control mode: speed control potentiometer (clockwise clicked open, continue to rotate clockwise from 1% to 99% speed)
Duty cycle: 0% -99% (0% position is the state of the switch off when the potentiometer is most on the left).
When the current is switched on, the 0.002A (long time no need to switch off the governor is no current).
Efficiency: the maximum efficiency is as high as 98% .
Volume: long 3cm (excluding potentiometer), wide 2cm, high 1.4cm
If you are using the speed control (dimming) to do the product, the shop can provide free
Custom service, can be in accordance with the requirements of the customer to modify the shape of the circuit board, installation
Mode, current and voltage parameters, add other functions, etc
Note that the governor is mainly used in motor speed control, if you are used to LED dimming, must ensure that the LED can also work in direct power supply, the dimming range of the speed governor is from LED to LED directly connected to the power supply is completely extinguished between dimming, if LED is directly connected with a power that will burn through dimmer the dimming is burned, which typically requires a series current limiting resistor, if you don't know how much resistance can contact customer service.

Product 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.
This breakout is best used for projects such as voice changers, audio recordingmpling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain.
Using it is simple: connect GND to ground, VCC to 2.4-5VDC.
The output pin is not designed to drive speakers or anything but the smallest in-ear headphones
- you'll need an audio amplifier (such as our 3.7W stereo amp) if you want to connect the amp directly
to speakers.
Specification:
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! You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume
about 6" away) which is good for attaching to something that expects 'line level' input without clipping,
or up to about 1Vpp, ideal 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!
For the best performance, use the "quietest" supply available (on an FOR Arduino, this would be the 3.3V
supply). The audio 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 audio equipment you're
using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your
device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling
capacitors, the 100uF cap is not required.

Description:
This moduel is an USB adpater /
programmer for ESP8266 moduels of type ESP-01.
It is conveniently fitted with a 2x4P
2.54mm female header to plug the ESP01
(according to illustration picture 2)
and configure or run it right away.
A large 1000μF cap will help getting a steady 5.0V VCC
from the USb bus and and jumper (on the right of the 2x4P header)(we don't offer any jumper !!!!)
will help configuring the GPIO0 line according needs.
The module is based on the USB-UART bridget CH340
from WCH which is compatible with all platforms.

Note : for an usage with Arduino ESP8266 platform and for Arduino IDE
it is necessary to switch manually the GPIO0 state for working mode,
in order to get a fully automatic upload it is most likely possible,
for a very limited effort, to assign an unused control line
from CH340 to driver the GPIO0 line
(probably at the cost of a necessary logic inversion),
refer to the CH340 datasheet and
most important to the NodeMCU V0.9
which use the CH340 and already implements this solution,
the schematic is open source and easily available.

Product Description
Features: Based on the I2C interface I / O expansion modules, use two I / O scalability eight I / O (up to 8 simultaneous use PCF8574, expanded to 64 I / O)
The most important feature: 1. Support two interface types access target board: Pin or row seat
2. Supports I2C bus cascade (by pin, row seat docking method, which can use multiple I2C modules)
Typical applications: for I / O resources were scarce MCU I / O expansion
The main resource: PCF8574, I2C interfaces, eight parallel
