Hi, I like to use the Pisound on my Project. But I also like to use a eInk Display. So I was wondering, if the Pisound needs all the GPIO Pins or is it possible to use a Breadboard and connect the Pisound manually and use the free GPIOs for other stuff? Best regards

Hi, see https://blokas.io/pisound/docs/specs/#raspberry-pi-pins-used-by-pisound . The ‘Pinout of Pisound Header’ lists all the unused GPIOs, routed to a separate smaller header.

Sorry noob here. How do you connect into that separate header? Can’t see any pinout exposed by the pisound board

It’s just 2x7 holes in the PCB. If you like, you can solder your own male or female header for use with jumper cables, or just solder wires directly to the desired holes.

Can’t see them :S just the RPi header HAT pins, is there a reference diagram out there? [image]

Thanks for the quick reply. This picture is of an earlier version oh ok check the picture here: Soldering the 5V bias jumpers I actually would like to use the I2C pins to drive an oled, which I read they are available (not used by pisound, Detailed Specs - Pisound Documentation ) but can’t fi…

Hi @Giedrius . Sorry to unearth this old post. But it often come to results of search about unused pin on pisound. Did I understand correctly that, by using the separate header, I can use all BCM pin mentioned as general purpose? I mean… If I don’t use any other hat or i2c. (second OT question ju…

Hi Giedrus, I’m “just” looking for a faster/easier way for connecting buttons/sensors to the rasp. I know some of GPIOs can be connected directly (like on Arduino, which includes pull up/down resistors on all pins) but I heard/read some of them on the rasp doesn’t have that. and we need to use ext…

All of the BCM pins that I’ve used had internal pull up and down resistors, they just can’t be controlled through sysfs gpio class interface (for that you must write and load your own pinmux device tree overlays), but you can use libgpiod or gpiod utilities which give you control over the pull up / …

Does Pisound using all GPIOs?
