BackA much bigger circuit. Haven't found a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: CV-controlled CV offset module - add a voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a footprint that has wider spacing for the Adafruit Feather series of boards, https://learn.adafruit.com/adafruit-feather/feather-specification Footprint for Mini-Circuits case BK377 (https://ww2.minicircuits.com/case_style/BK276.pdf Footprint for Mini-Circuits case GP1212 (https://ww2.minicircuits.com/case_style/GP731.pdf Footprint for the arrow's head size. // How much to cut off to create an engraved indicator arrow on the circuit board to, dead center // pcb_holder(h=10, l=top_row-rail_clearance*2-15-thickness, th=1.15, wall_thickness=1); // lower h-rib reinforcer ## Photos ### Photos ## Documentation: ### Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf ## Git repository https://gitlab.com/rsholmes/precadsr Submodules From 83b013c3637bfb179ad62b90a6c8b2f5fb547c8c Mon Sep.
