Raspberry Pi

The Raspberry Pi is a small single-board computer known for allowing to hack with hardware thanks to it's general purpose input/output (GPIO) pin header. The computer also has an Audio input/output, but the GPIO header has no analog-to-digital (ADC) converters. It can however be interfaced to any custom extension boards with 3V3 logic.

Properties

The Raspberry Pi does not have a general purpose Analog-to-Digital (ADC) or Digital-to-Analog (DAC) converter available on the GPIO pins. There are *hats* available which provide the neccessary hardware, for instance https://bc-robotics.com/shop/16-channel-analog-input-hat-for-raspberry-pi/

The GPIO pins of the Raspberry Pi have CMOS logic levels (3.3V). This is incompatible to TTL or +-10V Logic level of the THAT! Don't wire your THAT to the Raspberry Pi without logic conversion, otherwise you'll certainly break your poor Raspberry.

The Raspberry Pi in fact has an Analog audio Input/Output Jack (see Audio input). This can be used to interface the THAT.
