Product Description
SI5351 High Frequency Signal Square Wave Frequency Generator Signal Generator 5351 Si5351A
Never hunt around for another crystal again, with the Si5351A clock generator breakout ! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150 MHz.
The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.
We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic.
Best of all, we even have a great tutorial and library to get you started! Our code is designed for use with the Arduino microcontroller and IDE but is easily ported to your favorite platform with I2C support

Product Description
CJMCU- 9548 TCA9548A 1-to-8 I2C 8 -way multi-channel expansion board IIC module development board
You just found the perfect I2C sensor, them to your when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you can not have Two devices with the same same on the same SDA / SCL pins! "Are you out of luck? You would be, if you did not have this ultra-cool CJMCU-9548 1-to-8 I2C multiplexer!
Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command.
Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets Will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part.
we put this nice chip on a breakout for you so you can use it on a breadboard with capacitor, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a Solder the chip is very easy to use it with any logic level.
Product Features
The adapter is connected to an I2C device with multiple identical addresses on the same I2C port on the main control board for normal communication and use.
There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switches that can be controlled by I2C bus. This means that after 1 expander is transferred, 8 identical addresses can be connected to the same I2C port. The device is also in normal use. The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77 according to your needs. In theory, 8 expanders can be cascaded in the address of 0x70~0x77, and each expander can connect 8 devices with the same address. This realizes the same I2C port and connects 64 devices with the same address and uses them normally. Very powerful!
Compatible with IIC bus and system management bus (SMBus), active low reset input, support for hot insertion, low standby current, no glitch during power-up, support for voltages between 1.8V, 2.5V, 3.3V and 5V buses Level shifting.
Depending on the contents of the programmable control registers, any single SCn/SDn channel or combination of channels can be selected. When a timeout or other improper operation occurs, the system master can reset the TCA9548A by asserting the /RESET input low. Similarly, a power-on reset deselects all channels and initializes the I2C/SMBus state machine. Reset and initialization can also be achieved by asserting /RESET and there is no need to power down the part. The switch has a turn-on gate so that the VCC pin can be used to limit the maximum high voltage through the TCA9548A. Limiting the maximum high voltage allows different bus voltages to be used on each channel pair so that 1.8V, 2.5V or 3.3V components can communicate with 5V components without any additional protection, for each channel, external pull-up resistors The device pulls up the bus voltage to the desired voltage level. All I/O pins are 5V withstand voltage.

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.

Features
The module uses Taiwan-made high-quality control chip, externally expanded ultra-low on-resistance MOSFET, ultra-high efficiency (up to 95% ), and can reach 25W without heat dissipation
This module uses the original Sanyo filter capacitor with low ESR, and at the same time adds a level of LC filter unit in the rear stage, which can make the ripple voltage as low as 40mV, which can be applied to most occasions!
Scope of application
Battery regulator, you can use a 12V battery (10-14V) to output a regulated voltage at 12V.
Solar charging voltage stabilizes, you can stabilize the fluctuating voltage of the solar battery, and can charge the battery to avoid battery overshoot.
Power supply for your electronic equipment, ultra-wide voltage buck-boost design, wide applicable voltage range.
The pre-stage power supply of the system is designed with ultra-wide voltage buck-boost and a wide applicable voltage range.
Instructions/Precautions
This module is an adjustable automatic buck-boost module, and the output voltage can be changed by adjusting the blue adjustable resistor on the module.
The IN- (input negative), IN (input positive), OUT- (output negative), and OUT (output positive) marked on the module must be connected correctly, otherwise the module may be damaged.
This module has a short-circuit protection function. If the output is short-circuited, the system will lock the output to 0. Eliminate the short-circuit and re-power on to re-output.
