Introduction
The i.MX RT685 Evaluation Board (part number MIMXRT685-EVK) is designed for customers to evaluate the i.MX RT685 MCU.
It can be used with a range of development tools, including NXP’s MCUXpresso IDE. This User Manual describes Revision E of
the board with B0 silicon.
The EVK is subject to changes in future revisions.

The i.MX RT685 EVK includes the following features:
• i.MX RT685 Cortex-M33 core processor with Cadence Xtensa HiFi4 DSP
• Onboard, high-speed USB, Link2 debug probe with CMSIS-DAP protocol (supporting Cortex M33 debug only)
• High speed USB port with micro A/B connector for the host or device functionality
• UART, I2C and SPI port bridging from i.MX RT685 target to USB via the on-board debug probe
• Optional external debug probe connections with trace option (10 or 20 pin Cortex-M connectors, later required for trace)
