Pre-flashed firmware chip for AVR VCOs (version 2)

Regular price £4.99 £0.00 Unit price per
Tax included. Shipping calculated at checkout.

A pre-flashed firmware IC for the updated version of the AVR VCO - these are 4HP modules with all of the circuitry on a single board.

The principal difference between version 1 and version 2 firmware is that version 2 has fine-tune functionality by default.

The firmware source can be obtained from: https://bitbucket.org/yorkmodular/badtrip-vco/src/master/. The pre-flashed chip is aimed at people who are unable to compile and install their own firmware.

The chip's pinout is:

  1. RESET (connect to Vcc via a 10k resistor)
  2. Wave CV (0-5V)
  3. Pitch CV (0-5V)
  4. GND
  5. RANGE (+5V VCO, 0V LFO)
  6. OUTPUT (PWM signal - use RC filter or DAC to get analogue voltage)
  7. Fine-tune CV (0-5V)
  8. Vcc (5V max)
