Note:
1. Print serial port information for debugging: Pin3 and Pin4 of J8 without jumper caps, at this time USB_MUX_SEL=1, Type C connects
to the USB signal of the core board, it is USB to UART mode, at this time Type C prints the serial debug information of the core board.
2. Burning firmware to the RP2040: Pin3 and Pin4 of J8 with jumper cap, at this time USB_MUX_SEL=0, Type C connects to the USB
signal of RP2040, which is the burn-in interface of RP2040, set RP2040 into burn-in mode, which can update the firmware of RP2040
(update method: after connecting Pin5 Pin6 of J8 with jumper cap, then connect Pin7 Pin8 to reset RP2040 and make it enter into
burn-in mode).

Note:
1.The computer can recognize the board information: USB 2.0 Device interface on the core board, which can use Type C cable for data
communication.
2.Burning image to Jetson: While the board is powered up, press the RECOVERY button SW2 to enter the recovery mode, which
allows you to burn in the system of the core board.

Note：
1. Only one of M.2 Key B and Mini PCIe can be used at a time.
2. The insertion status of SIM card can be detected by the signal SIM_DETECT_1V8, which is high when SIM card is inserted and low
when it is pulled out.

USB3.1 TYPE-A x2 - J3
Note:
1. The upper and lower USB ports share a current-limiting IC, with a total power supply capacity of 2.1A maximum output current
(single can also be 2.1A). If over 2.1A, it will enter the over-current protection state.
2. The module pin names not directly connected to the USB connector pins but are routed to the input of the USB hub.
3. Orin NX module comes with 3 USB3.2, only one of which is used in reComputer and converted to 4 ways via USB3.1 hub. (USB3.1
TYPE-A x2 - J3 and USB3.1 TYPE-A x2 -J4).
4. The Type A is 5Gbps for all two, and only supports USB Host, not Device mode.
5. Provide 5V 2.1A.
6. Hot-swappable.

Note:
1. The upper and lower USB ports share a current-limiting IC, with a total power supply capacity of 2.1A maximum output current
(single can also be 2.1A). If over 2.1A, it will enter the over-current protection state.
2. The module pin names not directly connected to the USB connector pins but are routed to the input of the USB hub.
3. Orin NX module comes with 3 USB3.2, only one of which is used in reComputer and converted to 4 ways via USB hub. (USB3.1
TYPE-A x2 - J3 and USB3.1 TYPE-A x2 -J4).
4. The Type A is 5Gbps for all two, and only supports USB Host, not Device mode.
5. Provide 5V 2.1A.
6. Hot-swappable.

Note:
Support SPI interface TPM module, test with TPM2.0 Module with infineon SLB9670 (module not included)
Mini PCIe - J5
Note：
1.Support 4G/LoRaWAN®/GPS.
2.When using Mini PCIe 4G module, you need to set SIM_MUX_SEL to low level (Pin1 Pin2 jumper cap of J8 is connected), when
using LoRa module, you need to disconnect SIM card signal, at this time you need to set SIM_MUX_SEL to high level(Pin1 Pin2
jumper cap of J8 is disconnected).
3.Can be used as UART, IIC, GPIO.
4.M.2 Key B(J6) and Mini PCIe(J5) cannot be used at the same time.
