Description
This block is a simple potentiometer and LED in a slider form factor.
It is adapted from the Mutable Instuments Stages schematics.
Soldering
Pin headers don't come with just one position. Instead of that, the BOM has 2-position pin male headers that need to be broke into 2 pieces.
Usage
This block provides a silder potentiometer with a red LED.
Power
This modules needs to be connected to the 3V3A and GND lines from the power block.
On Daisy Seed, use the 3V3 Analog Power I/O on Pin 21, not the digital power.
All GND pins are internally connected in the block.
Signal
The signal IN drives the LED. It should be connected to any GPIO of the
target MCU, preferably non-analog GPIOs.
The signal OUT is the potentiometer value. It should be connected to any Analog GPIO of the
target MCU.
When using Daisy Seed as a development platform, see its pinout for details. The Daisy Seed has a total of 31 GPIOs, only 12 of which are analog.
Design
Gerber renders made with tracespace view.

Questions
How big is the Panel daisy PCB?
It measures 148 × 84.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel daisy use?
259 parts, built around the R-78E5.0-0.5, MCP6001U-I/OT, TL072 and MMBT3904. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Panel daisy KiCad files?
From the ohmtech-rdi/eurorack-blocks repository on GitHub, at the commit this page was made from: the board is blocks/kits/panel-daisy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel daisy design in my own project?
Its repository states no licence, so its author keeps all rights: ask ohmtech-rdi before reusing the design.
