Raspberry Pi is similar to most other single-board computers and microcontrollers it's unable to generate true analog output. A Raspberry Pi based PLC. The computer has only an analog output (no input) and the GPIO header has no analog-to-digital (ADC) converters. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware. MCC DAQ HATs are designed for the popular Raspberry Pi platform. Extended pins on the GPIO connector allowing stacking the Expander Pi along with other expansion boards. This board is designed to give the Raspberry Pi analog read capabilities similar to those found on the Arduino. Some of the interface libraries, such as pigpio or wiringPi, support this feature. The 26 pin GPIO port is duplicated on either side of the module, so more modules can be "daisy chained" together. The MCC 152 provides two 12-bit analog outputs with a 0 V to 5 V output range and 5 mA output drive, sourcing.
