Ardor
Ardor is an open source PCB design by balazsbencs: a 2-layer, 37 × 20.5 mm board with 20 components (14 distinct parts). It is built around the AMS1117-5.0, TL072. Filed under audio and displays & leds.
This is a DIY multieffects project with a Raspberry Pi and and Codec Zero and a Raspberry Pi Display 2. With Full NAM A2 support.
This folder contains the minimal guitar input buffer for Ardor.
Use this board between a passive guitar and the Raspberry Pi Codec Zero. Do not connect a passive guitar directly to the Codec Zero input.
Open buffer.kicadpro` in KiCad to view or edit the schematic and PCB.
Connect the guitar jack to GUITARIN. Connect GUITAROUT to the Codec Zero input. Follow buffer.kicadsch` for power and ground.
