38401-2
added 5V 8A power supply
added PCIe connector (rotate it compared to rev 1)
added CAN connector (requires external CAN transceiver module - 38163-3)
added mount pins of power in connector to GND
added another 220uF Tantal cap on bottom side
38401-3
changed MCU footprint from TSSOP-20 to UFQFN-28
supports STM32F042G6U6 and STM32L031G6U6 - dual rail power
added support for MCU flashing from Jetson via UART
changed R110 to 3.01k for maximum input current of 6A
changed main power supply from LT8646 to MIC28514
changed magnetics to XAL1010-103 with 14.8 mOhm DCR => better efficiency
extended e-fuse support for TPS26630/1 type - added two resistors
added 2nd FAN connector so that the FAN cable connection does not require an extension cable
38401-4
not released
38401-5
changed 8A power supply to 12A
changed 3.3V power supply and power it by 12V
changed MCU LDO (absolute max. input voltage 26V - if populated)
added discrete components for power up (no MCU)
moved FAN connector for better access
changed reverse voltage protection to MOSFET
changed over-current protection to fuse
version with 5V 8A power controller (derived from 38401-4.1)
changed back to input diode (for PoE PD support
This new JNX30 carrier boards have been designed for the Jetson Xavier NX primarily, but they also support the TX2 NX and Nano compute modules. A 5V 8A on-board power converter supports the high-power modes of the NX.
