The FS0400SKTEVM is the socketed evaluation board (EVB) for the FS04 Power Management Integrated Circuit (PMIC). It integrates a 64‑pin quad flat no‑lead (QFN) socket that allows users to easily insert and test FS04 devices. The board also includes a communication bridge based on the FRDM‑KL25Z development platform, enabling seamless connection to the FS04 graphical user interface (GUI) software to configure the device and program the one‑time programmable (OTP) registers. The FS0400SKTEVM contains all the hardware required to functionally evaluate FS04 configurations before performing the final OTP programming, making it ideal for development, validation and pre‑production testing.
