Assembly instructions

The PCB must be removed from the optical mouse first. Then the VDD, GND, SCK and SDIO pins must be soldered to wires leading to the microcontroller and its internal 5V power supply.

Insert the two M3 brass threaded inserts into the sensor holder by applying pressure. Attach the sensor to the sensor holder using 2 M3 screws.

Then follow the instructions in Figure 3 to assemble the three Thorlabs components with the sensor holder.

The lens must be glued to the PCB in the correct position, with the lens aligned with the optical flow sensor.

Attach the whole assembly on the rotary stage platform (e.g. at 0 or 90 degrees to the animal's anteroposterior axis).

Connect the pins on the PCB 5V, GND, and two digital pins as shown on the "electrical setup and configuration" page.
