Z-wave GPIO board

#1

Hi

Anyone tested z-wave GPIO boards on the X4 yet?
Pinout seems fine compared to raspberry pi, but i´m not quite shure how it works with non native raspberry pi addon on the X4.

#2

can you please share the z-wave GPIO boards info link? Maybe I can help.

Hi

Ofcourse, the board is Zooz 800

But all the z-wave boards either z-wave.me, zooz or aeotec use the same pinouts as they are based for raspberry pi.

Based on this image it seems like the following pins are in use.

3.3v - 5v
GPIO / SDA1 (i2c) - 5V
GPIO / SCL1(i2c) - GND
GPIO / GCLK (Function 1??) - TX-UART (function3 on x4)
GND - RX-UART (function3 on x4)

From what i see there might be pinout difference on 3 and 5.
As SCL and SDA is swapped.

The Radxa X4’s GPIO Pinout should basically match.

from this guide, we can know that we need enable I2C0 on pin_3 and pin_5, and enable uart on pin_8 and pin_10, you can use pico-sdk or micropython to initialize them.
