Hello ADI team,
I would like to ask about the power capability of the Jupiter SDR front-panel GPIO header.
I am planning to interface an ADIS16576 IMU with the Jupiter SDR, and I would like to know whether the 3.3 V supply rail provided on the front-panel GPIO header can directly power the ADIS16576.
According to the IMU requirements, the maximum current consumption may be around 100 mA. Could you please clarify:
1. What is the maximum current that the front-panel GPIO 3.3 V rail can safely provide?
2. Is this 3.3 V rail intended only as a light auxiliary supply for external logic, or can it be used to power a peripheral such as an IMU?
3. If 100 mA is too high for the GPIO header supply, would you recommend using an external 3.3 V regulator/power source instead, while only sharing SPI/GPIO signals with the Jupiter SDR?
My goal is to connect the ADIS16576 through SPI and, if possible, power it from the Jupiter SDR front-panel GPIO header for a compact setup.
Thank you for your help.
