# What new features does QBoard-II have, compared to the original QBoard?

QBoard-II features more compact dimensions; new PCB, interposer, and daughterboard designs; and the addition of a shielding lid. The upgraded design with 16 high-density RF and 48 low-frequency RC lines enables transmission from DC to 8 GHz. The new PCB design minimizes losses and crosstalk. This is useful for applications such as readout of superconducting resonators, sub-nanosecond gate-voltage pulses, and high-bandwidth frequency sweeps. It enables an easy upgrade with unchanged connector configurations.
