AD \/ DA Shield Module For Raspberry Pi And Arduino<br>Description:<br>AD \/ DA analog digital-analog-digital conversion module， compact， simple interface using the I2C interface， compatible with 3.3V \/ 5V level， it applies to the vast majority of the market development board. Single Supply， Low Power 8 COMS type A \/ D， D \/ A converter chip PCF8591， has 4 analog input channels， one analog output channels and an I2C bus interface. The device I2C slave address by A0， A1 Address jumpers decision， so no additional hardware， same below a I2C bus can connect up to four different types of devices. The chip also has a multi-channel analog inputs， keep track of on-chip 8-bit A \/ D converter and 8-bit D \/ A conversion. A \/ D and the maximum conversion rate of D \/ A is determined by the maximum transmission rate of the I2C bus<br>Feature:<br>Operating voltage: 3.3 V or 5 VInterface: I2CSingle power supply， the normal operating supply voltage range of 2.5V ~ 6V;Input \/ output I2C bus to complete the data， compatible 3.3V \/ 5V levelThe device address is determined by the two address pins， the largest cascade four modules4-channel analog inputs programmable as single-ended or differential inputs;8 successive approximation A \/ D converter; channel number can be configured to automatically increase the conversion function; keep track of on-chip functions;Multiplication with one analog output D \/ A conversion.Support multiple cascade interface， can be used independently， but also with the restaurant's multifunction sensor board to use a variety of programs diyprovide Raspberry Pi and arduino test routines<br>Package included:<br>1 x AD \/ DA Shield Module For Raspberry Pi And Arduino
