Employing the PCB for the control board worked well yesterday so one of the sensor boards was populated. When they were ordered, I specified that they be single-layer boards. This meant there were only solder pads on one side of the PCB. All the connections were in the correct places but the infrared sensor had to be soldered from the top which was inconvenient.

Small surface mount components were soldered by hand with a narrow soldering iron tip.

Soldered sensor board

Right-angle header sockets were soldered to each side of the sensor board and right-angle header pins were soldered to the ends of the LED strips. Given the length of the header sockets, it would have been possible to put the sockets closer to the center of the board so they would be flush wit the edge.

Sensor board connected inline with LED strips

As a test, the LEDs and sensor board were connected to the control board. The original LEDs and sensors were disconnected. A spectrum of different colors, progressing throug the rainbow, were assigned to the LEDs and there was no problem with the board acting as a conduit from one LED to the next. The receiver, operating on a four wire, also easily received information from a remote.
