Waveshare Raspberry Pi High-Precision AD/DA Expansion Board

The High-Precision AD/DA Board allows you to add high-precision AD/DA functions to the Raspberry Pi. It features ADS1256, an 8-channel 24-bit high-precision ADC with a 30ksps sampling rate, and DAC8552, a 2-channel 16-bit high-precision DAC. The board provides input/output interfaces via pin headers and screw terminals for connecting analog/digital signals.

Analog sensors

Avoid applying excessive voltage or current to the board to prevent damage.

Connect analog sensors easily using the pin headers and screw terminals provided on the board.

• Input Voltage: 0-5V,
• Output Voltage: 0-5V

• 1.: Connect the analog sensor module to the AD input pin headers.,
• 2.: Ensure the pinout is compatible with the Waveshare sensor interface standard.
