The FRDM-MCXE31B development boards are compact, scalable platforms designed for rapid prototyping with MCX E317/E31B microcontrollers. They feature industry-standard headers for convenient access to MCU I/Os, integrated open-standard serial interfaces, external flash memory, and an onboard MCU-Link debugger. To accelerate development, users can take advantage of additional resources such as the Expansion Board Hub for hardware add-ons and the Application Code Hub for ready-to-use software examples—all accessible through the MCUXpresso Developer Experience.
