Yes please! This incredibly small stereo amplifier is surprisingly powerful. It can deliver 2 x 2.8W channels into 4-ohm impedance speakers (@ 10% THD) and it has an i2c control interface as well as an AGC (automatic gain control) system to keep your audio from clipping or distorting.\u003c\/p\u003e\n\u003cp\u003eIf you don't want to use I2C to control it, it does start up with 6dB gain by default and the AGC is set up for most music playing. We do suggest using it with a microcontroller to configure it, however, since it's quite powerful. Settings are not stored in the chip, so you'll need to adjust any gain \u0026amp; AGC amplification settings every time the amp is powered up.\u003c\/p\u003e\n\u003cp\u003eInside 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 (89% efficient when driving an 8Ω speaker at 1.5 watts) - making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection but we could barely tell if it got hot. This board is a welcome upgrade to basic \"LM386\" amps!\u003c\/p\u003e\n\u003cp\u003eThe inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to the ground. 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\u003eComes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include 3.5mm screw-terminal blocks so you can easily attach\/detach your speakers, and some header in case you want to plug it into a breadboard. Speakers are not included, use any 4-ohm or 8-ohm impedance speakers.\u003c\/p\u003e\n\u003cp\u003eOur awesome tutorial and Arduino library will let you set the AGC configuration (you can also just turn it off), max gain, and turn on\/off the left \u0026amp; right channels all over I2C!

It will take care of turning your project on\/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.\u003c\/p\u003e\u003cp\u003eUsage is easy. First, set your desired delay by adjusting the on-board trim pot: nearly-all-the-way-to-the-left is \"once per 100ms\" and all-the-way-to-the-right is \"once every 2 hours\". Then, connect VDD up to your 3-5V power supply and then your project's power-in to the Drive pin. Finally, select a signal pin from your project to the Done pin. In your project's code or design, just make sure that it sets the Done pin high once it is completed with its task.

Either they were too slow, or too difficult to use, or required signing an NDA, or had limited functionality, or too expensive, or too large. So we shied away from carrying any general purpose microcontroller-friendly WiFi boards.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNO LONGER! \u003c\/strong\u003eThe CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b\/g, open\/WEP\/WPA\/WPA2 security, TKIP \u0026amp; AES. A built in TCP\/IP stack with a \"BSD socket\" interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets. It does not support \"AP\" mode, it can connect to an access point but it cannot be an access point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNew!\u003c\/strong\u003e As of 3\/20\/2014 we are shipping v1.1 which adds a tri-state buffer to the MISO pin so that you can use the CC3000 with other SPI devices on the same bus.\u003c\/p\u003e\u003cp\u003eWe wrapped this little silver modules in a tidy breakout board. It has an onboard 3.3V regulator that can handle the 350mA peak current, and a level shifter to allow 3 or 5V logic level. The antenna layout is identical to TI's suggested layout and we're using the same components, trace arrangement, and antenna so the board maintains its FCC emitter compliance (you'll still need to perform FCC validation for a finished product, but the WiFi part is taken care of). Even though it's got an onboard antenna we were pretty surprised at the range, as good as a smartphone's.\u003cbr\u003e\u003cbr\u003eEach order comes with one fully assembled and tested breakout and a small stick of header you can use to solder in and plug into a breadboard. We don't have a detailed tutorial \u003cem\u003eyet\u003c\/em\u003e but to get you started, we've got a fully working Arduino library that is based off of TI's codebase but adapted for use with the AVR. We also have example code showing how to scan the SSID's, connect to your access point and run DHCP, do a DNS lookup to IP address, ping a site and connect to a remote TCP socket such as a website and print out the page.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePlease note\u003c\/strong\u003e the hardware is good, but the library code does not yet support all of the CC3000's functionality. At this moment, SSID scanning, connection, DHCP, DNS lookup, ping, and UDP\/TCP client \u0026amp; TCP server connections (eg connect to a website and grab data or host a very short website) all work and are tested with example code. 0:16)\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cul\u003e\n\u003cli\u003eDimensions: 26.22mm \/ 1.03\" x 40.45mm \/ 1.59\" x 2.95mm \/ 0.11\"\u003c\/li\u003e\n\u003cli\u003eWeight: 3.46g\u003c\/li\u003e\n\u003cli\u003eEagleCAD PCB files, schematics, and Fritzing Library available in the product tutorial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRevision History:\u003c\/strong\u003e As of 3\/20\/2014 we are shipping v1.1 which adds a tri-state buffer to the MISO pin so that you can use the CC3000 with other SPI devices on the same bus.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eList of wifi access points used to test the CC3000 (by TI, not verified by Adafruit)\u003cbr\u003e \u003c\/p\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48620807291102,"sku":"vdz1787257976442","price":27.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/0705\/9422\/files\/adafruit-huzzah-cc3000-wifi-breakout-with-onboard-antenna-v11-discontinued_1.jpg?v=1787257985"}],"url":"https:\/\/primewearfashion.shop\/collections\/breakout-boards.oembed","provider":"My Store","version":"1.0","type":"link"}
