Not Supported

Angry PeteDecember 2024

Not supported, example code only works (I use that term loosely) for the A/D inputs. D/A Output was sketchy. Extra GPIO pins are not supported. There was some code which migrated to Git-Hub but has since disappeared. This product seems to a Clone of a Keyestudio product https://wiki.keyestudio.com/KS0213_Keyestudio_RPI_GPIO-PCF8591_Shield I spend 4 days downloading different library's and code sets with no luck. Connecting anything to the extra GPIO pins crashed the i2C communication. I found one reference in the Raspberry Pi Forum by a Kiwi who got it to work but was using the through pin GPIO, so no real success, the thread is closed. Maybe your coding skills are much better than mine (not hard), you're better at sniffing code on the web or you're some sort of masochist, but be careful of this purchase.

No, I don't recommend this product.

Rubbish product

The DoctorApril 2026

Typical duinotech rubbish. Poor documentation for dyi enthusiast. Documentation provided very technical and irrelevant. Simple question what are the jumper settings on the shield. Could not find this anywhere.
