About the Classd PCB

Classd is an open source PCB design by yope, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 58.4 × 73.7 mm, with 90 components from 37 distinct parts.

Other key parts include the TLV2464 and PAM8320. By type, the board carries 34 resistors, 28 capacitors, 8 connectors, 6 inductors, 4 transistors and 4 diodes.

It belongs with the audio designs in this gallery.

From the project

Python/Cython implementation of 3D printer firmware running on Linux

Kamaq is a 3D-printer (FDM) controller software running on an embedded Linux system. It is capable of controlling a RepRap-style 3D printer, but with different electronics. Stepper motor control is done using a 8-channel (7.1) USB audio device and some class-D audio amplifiers. Endstop switches are monitored via GPIO inputs (interrupt-capable) and temperature control for extruder and heated bed via standard hwmon-compatible ADC's and GPIO-outputs for heater control. The software has a web-iterface for machine control and monitoring. Why do it like this when there are already so many different…
