-TGGALVO card is a variant of the MicroMirror card(TGMM4) capable of running the same(or other) firmware. Instead of the MEMS drive electronics,​ it buffers, amplifies and outputs the DAC signals. ​

 +The TGDAC4 is a versatile card capable of performing many different roles. ​
 +
 +With the ''​GALVO_SPIM''​ firmware the card can replace a MicroMirror card(TGMM4). With the DAC outputs, it can connect to a 3rd party Scanner or Galvo amplifier. It presents as a Galvo to Micro-Manager and diSPIM plugin. The Voltage range can be adjusted with [[commands:​pm|Command:​PM]]. All other operation is similar to the [[micromirror|MicroMirror Drive Card]]
 +
 +With the ''​PIEZO_DAC''​ firmware the card can replace a Piezo drive card (TGADEPT). With the DAC outputs, it can control a 3rd party piezo amplifier. It presents as a Piezo device to Micro-Manager and diSPIM plugin. The Voltage range can be adjusted with [[commands:​pm|Command:​PM]]. All other operation is similar to the [[piezo_manual|Piezo drive card]]
 +
 +With the ''​SIGNAL_DAC''​ firmware the card behaves like a Signal generator. User can set the output voltage directly in millivolts. It can generate periodic waveforms with [[singleaxis|Single-axis functions]] and arbitrary waveforms with [[ring_buffer|RING BUFFER Multi-Point Save/Move]] modules. It presents as a SignalIO device in Micro-Manager( Supported by Micro-Manager version 1.4.23 night builds 9/4/2019 and after). Unlike the other firmware, the voltage range in this firmware is adjusted [[commands:​pr|Command:​PR]].
