If you're looking for an easy and low-cost way to get your digital sound files bumpin' then the MAX98357 I2S Amp Breakout is for you. It takes standard I2S digital audio input and, not only decodes it into analogue but also amplifies it directly into a speaker. Perfect for adding compact amplified sound, it takes 2 breakouts (I2S DAC + Amp) and combines them into one.\u003c\/p\u003e\n\u003cp\u003eI2S (not to be confused with I2C) is a digital sound protocol that is used on circuit boards to pass audio data around. Many high-end chips and processors manage all of the audio in digital I2S format. Then, to input or output data, three or four pins are used (data in, data out, bit clock and left-right channel select). Usually, for audio devices, there's a DAC chip that will take I2S in and convert it to analogue that can drive a headphone.\u003c\/p\u003e\n\u003cp\u003eThis small mono amplifier is surprisingly powerful - able to deliver 3.2 Watts of power into a 4-ohm impedance speaker (5V power @ 10% THD). Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient - making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection but we could barely tell it got hot.\u003c\/p\u003e\n\u003cp\u003eThe audio input is I2S standard, you can use 3.3V or 5V logic data. The outputs are \"Bridge Tied\" - which means they connect directly to the outputs, with no connection to the ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output to another amplifier, it should drive the speakers directly.\u003c\/p\u003e\n\u003cp\u003eThere's a Gain pin that can be manipulated to change the gain. By default, the amp will give you 9dB of gain. By connecting a pullup or pull-down resistor, or wiring directly, the Gain pin can be set up to give 3dB, 6dB, 9dB, 12dB or 15 dB.\u003c\/p\u003e\n\u003cp\u003eThe ShutDown\/Mode pin can be used to put the chip in shutdown or set up which I2S audio channel is piped to the speaker. By default, the amp will output (L+R)\/2 stereo mix into mono out. By adding a resistor, you can change it to be just left or just right output\u003c\/p\u003e\n\u003cp\u003eWorks great with Raspberry Pi, Arduino Zero, and any other microcontroller or microcomputer with I2S audio outputs.\u003c\/p\u003e\n\u003cp\u003eComes as an assembled and tested breakout board with a pre-soldered terminal block, with a small piece of optional header.

And radio operates exactly the same way: you send signals here, they receive them there.  The only difference is that there is no cat.\"\u003c\/p\u003e\n\u003cp\u003eSending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth® Low Energy!) but what if you want to send data very far? Most WiFi, Bluetooth®, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.'\u003c\/p\u003e\n\u003cp\u003eAlso, these Adafruit packet radios are simpler than WiFi or BLE, you don't have to associate, pair, scan, or worry about connections. All you do is send data whenever you like, and any other modules tuned to that same frequency (and, with the same encryption key) will receive. The receiver can then send a reply back. The modules do packetization, error correction and can also auto-retransmit so its not like you have worry about everything but less power is wasted on maintaining a link or pairing.\u003c\/p\u003e\n\u003cp\u003eThese modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node network or transmit data over a campus or town. The trade off is you need two or more radios, with matching frequencies. WiFi and BT, on the other hand, are commonly included in computers and phones.\u003c\/p\u003e\n\u003cp\u003eThese radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood.

We also carry an RFM69HCW 433 MHz version here. These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit.
