Instructions
Take part , which is the camera module, and fit it into the square holes on part . Make sure that the camera module has its port at the bottom, as shown in the visualization below.
Take 4 - M2.5x6 socket bolts and tighten them into the 4 holes to secure the camera module to part .
Take the Head Board and cut all the bottom pins using the flush cutters, as shown in the visualization.
After the bottom pins of the Head Board are trimmed flush, put it on the platform of part . Make sure that the 4 mounting holes align with each other.
Take 4 - M2.5x20 hex standoffs and tighten them into the 4 threaded holes on top of the Head Board to secure it to part .
Take the RPI and align its 4 mounting corners with the 4 - M2.5x20 hex standoffs.
Take 4 - M2.5x6 socket bolts to secure the RPI to the 4 - M2.5x20 hex standoffs.
Take the Media Hat Board and install it onto the RPI pins according to the visualization below.
Take part and put it on a flat surface with the inside of the part facing toward the ceiling.
Take the provided USB-A to JST-ZHR4 cable (yellow) and plug the JST connector end into the camera module . Then, route the wire through part until the USB-A connector is accessible through the back of the head.
Take the provided XT30 1000mm cable (red) and plug the male connector into the Head Board as shown in the visualization below. Then, route the wire through part as above, but through the big gap at the back of the head instead.
Then, align the 4 mounting holes on part with those on part according to the visualization below.
Take 4 - M4x14 socket bolts and tighten them into the 4 threaded holes on part to secure it to part .
Take the USB connector end of the USB-A to JST-ZHR4 cable (yellow) and plug it into the RPI USB port as shown in the visualization below.
Take the Ethernet 1000mm cable (blue) and plug one end into the RPI Ethernet port as shown. Then, route the cable through the gap at the back of the head.
Take the USB-C to USB-A 100mm cable (purple) and connect the Head Board USB-C port to the RPI USB port as shown in the visualization below.
Take the JST-XH to JST-XH 120mm cable (green) and connect the Media Hat Board JST port to the Head Board JST port as shown in the visualization below.
Take the single-ended JST-XH 300mm cable (orange) and plug it into the Head Board JST port as shown below. At the bare cable end, we will connect it to a WAGO, which will be connected to the speaker cable later on.
