Waveshare Raspberry Pi High-Precision AD/DA Board

Description

The Waveshare High-Precision AD/DA Expansion Board addresses the lack of integrated analog-to-digital and digital-to-analog conversion capabilities on the Raspberry Pi’s GPIO interface. This robust expansion board equips your Raspberry Pi with a powerful 24-bit ADS1256 ADC, offering 8 channels (including 4 differential inputs) with an impressive 30ksps sampling rate, alongside a 16-bit DAC8552 providing 2 channels of high-resolution analog output.

Designed for engineers and makers, the board features a standard Raspberry Pi 40PIN GPIO extension header, ensuring wide compatibility with various Raspberry Pi models and the Jetson Nano. It includes screw terminals and pin headers for flexible analog signal input, with the pinout aligning with the Waveshare sensor interface standard for easy integration of analog sensor modules. Onboard components like a 7.68M crystal, LM285-2.5 reference voltage, and test jumpers facilitate reliable and straightforward signal demonstration and development.
