Device Details
The seven-segment LED was earmarked for the STEM project however when searching online, there was very little information about this LED or the device’s pinouts.

With a package size of 25.10 mm x 19.05 mm, and 12.6 mm character height (approx.) the display uses two common anode connections per segment. The remaining connections on the LED relate to the seven segments and the decimal point. Each pin has two connections, one from either LED segment (either digit). The same situation applies to the decimal point.
Shown in the image below is a front view of the pin connections and corresponding segments.
The segment letter then numbered suffix 1/2 indicates that the two LED cathodes from each of the digit segments connect to that pin. The text CA1 and CA2 indicate the common anode connections.
