NI USB‑8452 為主介面卡,可用來連接內部積體電路 (I2C) 與序列週邊介面 (SPI) 裝置,並與之通訊。 USB‑8452 為隨插即用、匯流排供電的 USB 連結功能,為絕佳的可攜式解決方案,可溝通消費性電子產品與積體電路 (IC)。 當中也具有 8 個通用數位 I/O 通道,可用於多種應用,例如設定 I2C 裝置的位址、切換 LED,或閃控類比轉換晶片所常見的轉換與資料就緒通道。 相較於 PCI 介面卡,USB‑8452 可實際安裝於更靠近 I2C/SPI 裝置處,進而縮短 I2C 匯流排長度,並盡可能減少雜訊問題。 此外,此介面卡也具備 +5 V 與 GND,不需外接電源就能為電路供電。
