Features
- Convert MIDI messages into Control Voltage outputs
- Adapted from HAGIWO's MIDI to CV module
- Translate from Japanese to English using browser
- Removes Digital Outputs
- Has 4 Analog Outputs instead of 2
- XAIO RP2040 CPU
- Arduino MIDI library has not yet been ported to Pico so will need to use CircuitPython
- MIDI In
- Standard MIDI Jacks
- MIDI out jack for future functionality
- (4) 0-5V Analog CV outs
- MCP4822 12-bit D/A - SPI Interface
- Use with SYNTH-VCO-01
- CV_1 = V/OCT
- CV_2 = MOD
- Standard EuroRack 16 pin header
- Supports 12V in with on-board 5V regulator
- 5V regulator can be not installed if 5V is available on EuroRack connection
- Card is not a Eurorack card
- Probably too deep, needs cabling
- (6) 6-32 Mounting holes
- Stacks with SYNTH-VCO-01 card
