DFU KEY: At any time, you can press the DFU button and power on + again to enter the DFU mode, but you need to connect the URST jumper to MI052 Ref CLK input IPEX: You can connect a cable to input an external high-precision reference clock for AD9363 through the IPEX interface. The main level should not exceed 3.3V, and the EXCLK jumper needs to be connected to GND to turn off the built-in clock. Calibrate the frequency of the built-in VCTCXO: The frequency of the 40M clock can be fine-tuned by adjusting the adjustable resistor next to the VCTCXO, provided that you have a reference signal source. Micro-SD: Support booting via SD card, need to connect SD-H jumper to 1V8.
