Arduino Support Library: https://github.com/AdamKeher/Pico-Audio-Arduino ## About -The Pico Audio is a fully featured audio solution specially made for the TinyPICO ESP32 development board. The Pico Audio features an I2S Stereo DAC, I2S Mono MEMS Microphone, builtin 3.7W Stereo Amplifier, I2C GPIO Extender and built-in MicroSD card reader. +The picoAUDIO is a fully featured audio solution specially made for the TinyPICO ESP32 development board, featuring an I2S Stereo DAC, I2S Mono MEMS Microphone, builtin 3.7W Stereo Amplifier, dedicated Headphone Amplifier, I2C GPIO Extender and built-in MicroSD card reader. -The Pico Audio utilises a low power NXP UDA1334A IC featuring a clear digital 16/20/24 bit, 44.1kHz, stereo audio DAC. Accompanying the DAC is a Knowles SPH0645 I2S digital mono microphone. This miniature low power MEMS microphone provides a low noise, 24 bit, 44.1kHz stream. Complimenting the DAC is the powerful Maxim MAX98306 3.7W stereo class D amplifier. +We utilise a low power NXP UDA1334A IC featuring a clear digital 16/20/24 bit, 44.1kHz, stereo audio DAC.

Complimenting the DAC is the powerful Maxim MAX98306 3.7W stereo class D amplifier with stero speaker terminals and a Texas Instrumets TPA6132A2 stereo headphone amplifier with 3.5mm audio jack. -The Pico Audio has a mounting socket to host the TinyPICO development board and connects all of these great features together in a seamless and easy to utilise footprint measuring a tiny 32 mm x 47 mm (1.2in x 1.86in). To provide maximum connectivity the board features a built-in MicroSD card reader and GPIO extender to hookup 8 inputs and outputs for all of your button and LED needs. +A simple mounting socket hosts the TinyPICO development board and connects all of these great features together in a seamless and easy to utilise footprint measuring a tiny 33 mm x 57 mm (1.29in x 2.24in).

This footprint was designed to help hold the alignment of a through-hole component (i.e. 6-pin header) while soldering it into place. You may notice that each hole has been shifted either up or down by 0.005 of an inch from it's more standard position (which is a perfectly straight line). This slight alteration caused the pins (the squares in the middle) to touch the edges of the holes. Because they are alternating, it causes a "brace" to hold the component in place. 0.005 has proven to be the perfect amount of "off-center" position when using our standard breakaway headers. Although looks a little odd when you look at the bare footprint, once you have a header in there, the alteration is very hard to notice. Also,if you push a header all the way into place, it is covered up entirely on the bottom side. - + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +>NAME +>VALUE + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +>NAME +>VALUE + + + + + + + + + +Fixed LDO Voltage Regulator, 2.2V to 5.5V, 190mV Dropout, 3Vout, 150mAout, XDFN-4 + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +>NAME +>VALUE + + + + + + + + + + + + + + + + + + + + + + + + + +>NAME +>VALUE + + + + + + + + + + + + + + + + + + + + + +25-mW DIRECTPATH?
