Stacking RB-Wav-08

I need to read 16 analog inputs. Can I stack two of the RB-Wav-08 on a single Raspberry PI?

Thank you

Hi @narenkoka

You wouldn’t be able to stack them, because of the pin out:

Pin Symbol Description
1, 17 3.3V Power supply (3.3V)
2, 4 5V Power supply (5V)
3, 5, 7, 8, 10, 18, 22, 24, 26, 27, 28, 29, 32, 36, 38, 40 NC NC
6, 9, 14, 20, 25, 30, 34, 39 GND Ground
11 DRDY ADS1256 data ready output, low active
12 RESET ADS1256 reset input
13 PDWN ADS1256 sync/power off input, low active
15 CS0 ADS1256 chip select, low active
16 CS1 DAC8532 chip select, low active
19 DIN SPI data input
21 DOUT SPI data output
23 SCK SPI clock
31, 33, 35, 37 GPIO extend to sensor interface

You would need a 16 Channels AD/DA Converter, which I cannot find in RobotShop’s Catalog.
