FAQ/Different between V4 4 and V4 5
From Miniscope
What's different between V4.4 and V4.5?
V4.5 (sold by OEPS) adds voltage-detection circuitry intended to work with an upcoming OEPS DAQ revision that will provide active over-voltage protection and regulated power delivery. With the current DAQ the new feature is inactive and V4.5 behaves identically to V4.4. Imaging hardware, optics, and the assembly procedure are unchanged. V4.4 and V4.5 are fully interchangeable within the same experimental setup. Contact OEPS for more information.
