Specific layout considerations for the and thermal management. RF & Connectivity : Transceiver logic using the WTR2965 .
Synthesizing these parts, "c3e-mb-pcb-v4" tells a coherent story: This is the fourth printed-circuit-board revision of the main motherboard for the C3E product family. For an engineer picking up this board, the string conveys immediate expectations—schematics labeled v4, a bill of materials frozen for that revision, specific known errata fixed since v3, and a set of test points and mounting holes consistent with the final mechanical design. It also signals compatibility: firmware built for v4 must not assume register mappings or pinouts from earlier revisions. c3e-mb-pcb-v4
