General Pisound Specifications
Pisound conforms to Raspberry Pi’s Hardware Attached on Top (HAT) specifications and connects to Raspberry Pi via the 40-pin header. The shield is slightly bigger in length (56 mm x 100 mm) than Raspberry Pi itself. It has two female DIN-5 connectors for MIDI in/out and two ¼" (6.35 mm) stereo jack connectors for stereo audio in/out. There are two pots for gain and volume control, a programmable button and MIDI activity and input clip LEDs.
| Parameter | Value |
|---|---|
| Current Draw | < 300 mA @ 5.1 VDC |
| Dimensions | 56 mm x 100 mm |
| Weight | 67 g |
Power Supply
Pisound powers up from Raspberry Pi's power supply via pins on the GPIO header and consumes no more than 300 mA at 5.1 VDC, so we recommend to use the official 5.1 VDC RPi power supply for RPi version 1, 2 and 3 or USB-C Power Supply for RPi version 4.
Supported Raspberry Pi Models
| Compatible Models | |
|---|---|
| Raspberry Pi 41 | Raspberry Pi 3 |
| Raspberry Pi 3B+ | Raspberry Pi 2 version 1.2 |

-
Full compatibility since Pisound hardware version v1.1.
Pisound v1.0 can still be used with the RPi model 4, but there's a known issue caused by a power supply design change in Raspbery Pi 4, see this topic in our community for detailed information and software workaround details.
