RTB_E12
This module implements a compact 12-channel WS2811 PCB designed to fit within a signal's socket. Connectivity is provided via an FFC cable to an adapter board (P15) mounted beneath the layout, which allows the signal to be easily detached—for example, during transportation. The E12 can be cascaded with other WS28xx compatible chips.
