== Control Voltages Amplifier ==

* Three in/outs
* 5V in, 10V out
* Built on [[ER-PROTO-02]] card
* 2x5 Power connector

=== Application ===

* Erica Synths DIY Sequencer has 10V control signals in
* HAGIWO (and many others) uses Arduino Nano(s) to create 5V control voltages
** Ex: [[ER-BEZIER-CV]] sends out gate
* This card translates the GATE signal from 0-6V to 0-10V
