PCB Board Component Overview
Thought for 47 sec
The OSDL – Board V2 – 3 Final is built around a CD4053BE triple analog switch at U1, enabling flexible routing of analog signals between inputs and outputs. Three precision shunt resistors—R1, R2, and R3—set bias and attenuation levels. Signal connections are made via a series of 2.54 mm pin headers (J1, J2, J3, J4, J6, J7, and J11), offering versatile I/O options. Multiple Ground symbols ensure a solid reference plane for stable operation and noise suppression.
