The Maury MAURY is powered by NXP i.MX 93 processor, which is designed to meet the latest market requirements of connected streaming audio/video devices, scanning/imaging devices and various devices demanding high-performance and low-power.
...
The main connector of the Maury MAURY is the J1600 SMARC connector.
...
This chapter includes a short description of all interfaces of the MauryMAURY. Please consult the processor datasheet for detailed information.
2.1 Power Supply
The Maury MAURY can be supplied by a single +5.0V power supply.
...
Name | Description |
|---|---|
5V_SLEEP | 5V power input. This supply controls the STM32. STM32 MCU controls reset and power to the i.MX 93 processor. |
GND | Ground input |
VDD_RTC | 3V power supply to supply the RTC on the MauryMAURY |
2.2 Control signals
