Basic dimensions of core board：long60mm*wide41mm*20mmhigh. Core board weight：16gram(g).

This product sells well to European and American customers，It's greatly shortenedDIYEngineer's time and cost of plate making！

ADAU1452/1466The core board is ShenzhenMEDIAWORKSThe company isSIGMADSPEngineer or audioMAKER/DIYERQuick development tools provided，It uses4layerPCBBoard design，Power layer，Signal layer，GNDEach layer has a separate circuit layer and is well isolated，In order to ensure high qualitySNRSignal to noise ratio。 The board integratesADAU1452or1466 DSP，Reset circuit，USBIDebug port（And can be passed throughUSBIPower the core board separatelyDC 5V），5Vreach3.3VOfLDO，12.288MPassive crystal oscillator，SPI EEPROMExternal storage，Start mode setting, etc，And through the double row pins on both sides（2*15，2.54mmspacing）Take all of themI2Ssignal，SPIsignal，I2Csignal，SPDIF TX/RXmouth，AUX ADCWait until all of them are reserved，For customers to choose in the design of the bottom plate design。

After purchasing the core board，We will provide corresponding informationPDFVersion of the schematic and key dimensions of the data to the customer。Because the board is not standard with audio backplane，So we only provide simple routines（asEQ, LIMITER, CROSSOVERetc.）And a brief introduction document，Please refer to the specific programming methodSIGMASTUDIOOnline help or otherSIGMADSPUser manual of development board，SSThere are a lot of algorithms in，As shown in the picture5As shown in。

ADAU1452andADAU1466yesPin and code compatible，The difference is thatADAU1466Memory ratio ofADAU1452It's more than twice as big，That is to say, if it is used to achieve delay and other effects，1466Longer delay or better reverberation can be achieved。

The comparison table is as follows：

instructions： 1. When the power supply to the core board is normalDC 5VAfter power input，LDOWill be available for all devices on board3.3VDigital voltage of，At the same time, the red power supplyLEDThe lights will be on。The core board has burned a flash program before delivery，When the lower left self start switch jumps to self start mode，A power on or press the top left reset button，Blue on the top rightLEDThe light will be on and flashing，Press the button below it，LEDIt's always on，Release it again，LEDThe lights continue to flash。This means that the core board is working properly。

    2. The default mode of the core board isSPIAsUSBIDebug and start mode，Refer to the corresponding startup interface configuration description in the schematic diagram，May be amended asIICStart mode。
