Reference test source code easy to build and use. - Works strait out of the box with the available reference source code. Thoughtful, quality board design. Reference source code simple to build into executable on Raspbian. Easy device connection via convenient terminal block or pin headers. Feed through GPIO header provided for easy access to any other Pi GPIO connections you may already have in your project. Mounting standoff hardware not included, but not necessary for lab bench development activities. Adds enough height to preclude use of standard Pi enclosure. Power connection provided on both terminal block and pin headers for driving input devices. I'm using power on the terminal block for driving string potentiometers used as position sensors. Review: Don't give up too soon! - This board will expand your knowledge of how the hardware and software work together. Pay close attention to the version of the Broadcom library you are directed to install. Get the one being pointed to in the link. (hint: you have to roll your mouse over the link to see that it is a link) Then compile and install as directed. I got it right on my second pass and every thing works as advertised. On my first pass it hung on reading the chip ID. I know this because I added print statements to the code to see how far it was getting. It's true the documentation could be better organized but it is all there if you look hard enough. I can see me getting more of these in the future after I come up to the level this board is capable of pulling me up to. Take you time and follow the instructions and you shouldn't be disappointed unless of course you are looking for a $10,000 board via a $37 purchase. ## Features - The High-Precision AD/DA Board allows you to add high-precision AD/DA functions to the Raspberry Pi - Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate - Onboard DAC8552, 2ch 16bit high-precision DAC, up to 30MHz output - Onboard input interface via pinheaders, for connecting analog signal - Features AD/DA detect circuit, easy for signal demonstration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0105DPYNO | | Best Sellers Rank | #9,769 in Single Board Computers (Computers & Accessories) | | Customer Reviews | 3.5 3.5 out of 5 stars (33) | | Date First Available | June 19, 2015 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.353 ounces | | Item model number | High-Precision AD/DA Board | | Manufacturer | WaveShare | | Product Dimensions | 7.09 x 3.94 x 3.54 inches | ## Product Details - **Brand:** waveshare - **Connectivity Technology:** GPIO - **Included Components:** High-Precision AD/DA Board, RPi screws pack (2pcs) - **Model Name:** WAV_11010 - **Operating System:** Linux ## Images ![Waveshare AD/DA Expansion Sheild Board for Adding High-Precision AD/DA Functions Compatible with Raspberry Pi Onboard ADS1256 DAC8552 Sensor Interface - Image 1](https://m.media-amazon.com/images/I/61ys9f-72aL.jpg) ![Waveshare AD/DA Expansion Sheild Board for Adding High-Precision AD/DA Functions Compatible with Raspberry Pi Onboard ADS1256 DAC8552 Sensor Interface - Image 2](https://m.media-amazon.com/images/I/713WpGqTLYL.jpg) ![Waveshare AD/DA Expansion Sheild Board for Adding High-Precision AD/DA Functions Compatible with Raspberry Pi Onboard ADS1256 DAC8552 Sensor Interface - Image 3](https://m.media-amazon.com/images/I/71GHknF4fxL.jpg) ![Waveshare AD/DA Expansion Sheild Board for Adding High-Precision AD/DA Functions Compatible with Raspberry Pi Onboard ADS1256 DAC8552 Sensor Interface - Image 4](https://m.media-amazon.com/images/I/71yiz91+ROL.jpg) ## Questions & Answers **Q: Will this work on a Raspberry Pi 4?** A: I am using this board with Raspberry Pi 4 and while it works with it, so far I could only use C language to program it - I am not aware of a Python library for this board. **Q: Would it be possible to hook this up to a pi zero w? also, would it be possible to just grab the audio data from hdmi with this board?** A: Yes,It can be used with pi zero w. But I don't know what you mean for 'grab the audio data from hdmi' , this item does not include the HDMI Interface . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to intall.

I found it runs on a RPi2B at an actual sample rate up to 25 kHz (at the 32 kHz setting), but the noise at that rate is so extreme I think it's not 100% working. But if you need that rate you probably don't want a sigma-delta ADC anyway. At 2 kHz or below the noise is reasonable, and at the lowest speed it is quite good. I measured a low-noise source (AA battery) and get only 1.2 counts RMS noise and 5 counts pk-pk noise sampling for 10 seconds at 2.5 Hz so at that speed it does warrant the claim 24 bit ADC. My code is "ADS1256_read.c" in the "jbeale1 / DataAcq" folder on github. Another person did a Python library which is in the "ul-gh / PiPyADC" folder on github. I took off a star for the state of their demo code, but the hardware is usable and the price is surprisingly low. The waveshare wiki site does have the circuit board schematic also. I didn't try the DAC8552 chip onboard, but note the Amazon page here claims "up to 30MHz output" which is wrong, check the datasheet: up to 30 MHz *input clock* and you need 24 bits for each update so you can't even make a 1 MHz square wave, and also there is an output settling time. Also on the Raspberry Pi, I am not sure about 30 MHz SPI clock; the Waveshare demo code uses 1 MHz. ## Frequently Bought Together - Waveshare AD/DA Expansion Sheild Board for Adding High-Precision AD/DA Functions Compatible with Raspberry Pi Onboard ADS1256 DAC8552 Sensor Interface - Raspberry Pi 4 Computer Model B 8GB Single Board Computer Suitable for Building Mini PC/Smart Robot/Game Console/Workstation/Media Center/Etc. - UCTRONICS Front Removable 1U Rack Mount for Raspberry Pi, with 4 Mounting Brackets for Raspberry Pi 5, 4B, 3B+/3B, and Other B Models --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/119533810-waveshare-ad-da-expansion-sheild-board-for-adding-high-precision](https://www.desertcart.tn/products/119533810-waveshare-ad-da-expansion-sheild-board-for-adding-high-precision) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-22*
