Cv scale offset
About the Cv scale offset PCB
Cv scale offset is an open source PCB design by carr-james, published on GitHub. It is a 2-layer board, with 12 components from 4 distinct parts.
Other key parts include the TL072IP. By type, the board carries 4 capacitors, 4 resistors and 2 ICs.
It belongs with the audio designs in this gallery.
From the project
Reusable Eurorack circuit blocks (KiCad 10 design blocks) and house design rules
Sets the range of a control voltage with two board trimmers.
U1A buffers the input so the block loads nothing. RV1 attenuates that by a factor of 0 to 1. U1B amplifies by 2 and subtracts an offset taken from RV2.
Both controls are trimmers on the board. Nothing here reaches the panel. The range is a build-time decision, not a performance control.
The block does not drive a jack. Follow it with cv-output.

Cv scale offset: common questions
How big is the Cv scale offset PCB?
The Cv scale offset has 2 copper layers and is 1.6 mm thick.
How many components are on the Cv scale offset?
12 components, from 4 distinct parts. The full bill of materials is listed on this page.
Where can I download the Cv scale offset design files?
From the carr-james/eurorack-blocks repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Cv scale offset design in my own project?
The repository has no license, so all rights stay with carr-james. Use it as a reference, and ask the author before reusing the design.
