Module is available as a DIY project only.
No info about availability.
Dual OTA VCO with sync, FM, PWM, etc
From the announcement:
"A dual tri-core VCO intended for the next WAMOD workshop. PCBs may be available in the future. Quite simple design, not great tracking or stability but decent enough and very usable."

These merchants probably sell this module. Huh?
