'''NOTE：'''

This DIDO module supports also '''Raspberry Pi 5''' hardware, but need to change the gpio no, refer to [[#FAQ]] Q3

The DIDO is upgraded to Version 1.3, and it's support the raspberry pi 4 model B now. We have only reduced the PCB size, nothing else has changed.

How to use the DIDO on Raspberry PI 4B Please refer to [[File:How to use the DIDO on Raspberry PI 4B-EN.pdf]]

DIDO module includes components like relays,switches, gigital and analog I/O that will allow for connection to sensors ,motors, lights, etc.
and be controlled by the Raspberry Pi board.

The digital DIDO module interface board fits the original Raspberry Pi models A and B.
DIDO module has been redesigned to fit the Raspberry Pi models A and B.

== Fitting instructions ==
'''Warnings'''
* Ensure that no power is supplied to Raspberry Pi, or DIDO boards
when plugging or unplugging.
DIDO sits neatly above the Raspberry Pi and connects using the expansion
connector. Take care to ensure all expansion pins are lined up with the holes on the
DIDO socket. Check the alignment for left and right, and front and back before
pushing down and never force the boards together if they don’t slide smoothly.

Q3: How to get DIDO working on Raspberry Pi 5
</div>
<div class="mw-collapsible-content">
A: When use it on the Raspberry Pi 5, You may encounter the following errors：

[[File:DIDO-error-on-pi5.png|800px]]

Need to run the command:
sudo nano /usr/lib/python3/dist-packages/pifacecommon/interrupts.py
Then search the <code>GPIO_INTERRUPT_PIN = 25</code> line and change '''25''' to '''596'''

PS: Run 'cat /sys/kernel/debug/gpio' to get new gpio no on raspberry pi 5
