Raspberry Pi High-Precision AD/DA Expansion Board

There's no AD/DA function on the Raspberry Pi GPIO interface, this may trouble you in the Pi development. However, it won't be a problem anymore. The Raspberry Pi High-Precision AD/DA Expansion Board allows you to add high-precision AD/DA functions to the Raspberry Pi.

Recently added to Mycodo

The A/D portion of this board was recently added to Mycodo - a graphical sensor and controller environment that runs on raspberry pi. https://github.com/kizniche/Mycodo There is a python library that will work with the A/D named PiPyADC https://github.com/ul-gh/PiPyADC Python cannot sample above about 1k samples per second, however lower speeds are required for precision.

Excellent Board ... Highly Recommended

The RB-WAV-08 is an ideal platform for interfacing with analog systems through the PI Raspberry platform. The board is high quality, easy to work with, and comes from the factory with an on-board light sensor, potentiometer and LED's to test board functions. On a side note, I had a bit of trouble with my PI 3, unrelated to the RB-WAV-08 board, and customer service from Robotshop responded to my support request in a few hours and I was able to resolve the problem. I followed the instructions downloaded in the documentation package from Robotshop and had the software compiled and working in about 3 minutes. Thanks to the on-board pot and led's I could immediately test the software. Overall, I'm impressed. This is a well supported, high quality board at a bargain price.

Great Product, Great Service!

The product is original make, and arrived reasonable fast by regular mail. Nothing seems broken. Fits perfectly to raspberry pi. Haven't done actual testing yet, but I don't expect problems from its looks. Thanks guys!

Good Hardware, Docs and S/W Lacking

The hardware worked as advertised *after* I spent several frustrating hours deciphering the schematics and writing my own Python drivers to talk to it. If the board came with solid docs and code, I would have given it a 5. If you're looking for Python interface code, I've open sourced mine which makes use of 2 other projects (one for the ADC, one for the DAC). https://github.com/makahn64/waveshare_a2d_d2a_python

As described, fast shipping.

Nice board, didn't use it with a pi but with a Cypress PSOC 4.
