Tanotis New GY-MAX4466 Electret Microphone Amplifier with Adjustable Gain for ArduinoDescription: 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
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, audio recording/sampling, and audio-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" 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!
Using it is simple:
connect GND to ground, VCC to 2.4-5VDC.
For the best performance, use the "quietest" supply available (on an 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.
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 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 audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.

Not your average Billionaire's Nanny
Format: Kindle
A unique twist on a Billionaires Nanny plot. I was immediately drawn into the story and it kept me guessing on how it would unfold. The chemistry between Tessa, Damien, Theo and Nico was HOT. The spicy scenes were intense and everything you would expect from a Cassie Cole book. I had a difficult time connecting with Tessa. Some of her actions and unexplained entitlement to know everything going on around her seemed off to me but Theo was my absolute favorite.

Hot tamales!
Format: Kindle
So Nico, using food as his love language. Damien, stoic and mysterious. Theo strong and constant. All revolving around Tessa, whose more than just a nanny. Absolutely loved it. Steamy and packed with awe and wonder as they travel the world in the name of art. Couldn't put the story down.

Entertaining Sweet and Steamy Billionaire RH Romance🔥❤️🔥
Format: Kindle
In this entertaining sweet and steamy,billionaire, RH romance Tessa is working as a server at a party for the Hawthorne Conservancy where she meets a cute little girl Tabitha who is going to change her life. After the party Tabitha can't stop talking about Tessa so her father Damian who's a billionaire takes it upon himself to just show up with no warning. The purpose of the surprise visit is to offer Tessa the job as Tabitha's nanny which she really has no chance of refusing. Once Tessa accepts the job she meets Nico the chauffeur as well as Theo the head of security Damian,Nico and Theo go everywhere and do everything together. What Tessa thought was going to be a simple nanny job has turned into so much more. I don't want to say anymore and ruin it for anyone else with spoilers. You really need to read this entertaining, sweet and steamy, billionaire, RH romance to see what happens. I would recommend reading this book.
I received a free copy of this book via Booksprout and am voluntarily leaving a review.

Just okay
Format: Kindle
This is the second book from this duo I’ve read. And I just can’t get into it. Like Cassie Cole books. Sasha Moon is new to me. This book has a decent storyline. Intrigue. Exotic places. Dangerous underworld. Tessa is plucked from her waitressing job to nanny for Damien. The billionaire art mogul and his 2 friends. They are deep into a new project that they call the Legacy Collection. She’s whisked around the world as she Nanny’s for the billionaire. My problem is that I just do not like Tessa. She’s quickly inserting herself into business she knows nothing about. Creeping around places she shouldn’t be and the billionaire and his security is okay about it. A slight talking to and that’s all. I like a strong female character, but she was often a brat. She just wasn’t likable to me. She was tolerable once they arrived in Greece, but I was too far gone at that point. Good level of spice. The scenes were hot. The guys were likable. Overall, I couldn’t wait to finish it but I found myself often putting off picking it up

Great Story!!
Format: Kindle
This was a great story however, it did seem a little short. Maybe a little rushed, but that could also be because I wanted a little more development of the characters as a family :).
Also, I love how this story doesn’t seem like there are two different authors! Whew :). I love that!!!
The only real criticism I have is that there are too many characters with names that start with the letter “T” and it makes reading the story a little confusing.
