Design a Custom BoardHardware security chip that authenticates third-party payloads to DJI aircraft over the E-Port and E-Port Lite interfaces. Without it the Payload SDK will not function. Operates from 1.62V to 5.5V across -40°C to 85°C and communicates over I²C at address 0x2A up to 400kHz. The PSDK library handles the certification protocol and security algorithm internally, so an integrator only registers a standard I²C device interface. Requires PSDK 3.10.0 or later and is supported on Matrice 4E/4T and subsequent models.
Hand-soldering 0.5mm pitch USON is tedious and error-prone; a breakout board with standard 2.54mm headers lets you prototype on breadboards without reflow. The tiny 3×2mm package also makes direct integration risky during development. This board bridges the gap between evaluation and production.
