v0.1

Specifications

Parameter Value
Width -

+12 Current -
-12 Current -
+5 Current 0mA

Features

  • 6 track trigger sequencing
  • Seperate CV-Switchable Fill track for each track
  • Different range of functions for the buttons, more information here

Quirks and Problems

  • I managed to forget to power the microcontroller
  • Realised that I used a SP5T switch for the track selection
  • The module cannot be taken apart once it's assembled

v0.2

Specifications

Parameter Value
Width -
Depth -
+12 Current -
-12 Current -
+5 Current 0mA

Features

  • Fixed missing power for microcontroller
  • Redid the track selection traces
  • Made the button disconnectable for easier fixing and maintainance

Quirks and Problems

  • For some reason the code does not work anymore
  • Too hard to find SP6T switches, used a SP8T switch instead
  • I realized during development that the RPI Pico's ADC can only handle 3.3V, however I'm feeding it 5V, so analogue functions won't work
