Image Added 2. Port DescriptionNo. | Name | Illustration | Specifications & Operation | 1 | DC Power Input | Image Added | DC 12V 3A. Please use the matched power adapter.
DC port size: 5.5-2.1MM | 2 | HDMI Input | Image Added | HDMI input, up to 4K 60Hz supported. sudo systemctl disable SophonHDMI reboot sudo insmod /mnt/system/ko/v4l2_lt6911.ko cd /opt/sophon/sophon-soc-libisp_1.0.0/bin/ ./isp_tool_daemon The current demo only supports 4K60. Modify the firmware for other resolutions. | 3 | Recovery Key | Image Added | For USB firmware upgrade. | 4 | HDMI Output | Image Added | Supports up to 4K 60HZ. | 5-6 | Ethernet | Image Added | 1000M x2
ETH1: Static IP; ETH0: Dynamic IP | 7-8-9 | USB Ports | Image Added | USB1: USB3.0 OTG port for firmware upgrade (TF card upgrade recommended).
USB2 & USB3: USB3.0 HOST ports. | 10 | UART & GPIO Ports | Image Added | RS485 – ttyS1, maximum baud rate 115200bps
RS232 – ttyS3, maximum baud rate 115200bps
Test with the supporting UART script. Max load: 1A. Wire length shall not exceed 1M. GPIO-IN Low level or floating: CPU reads "1".
High level (3.3-12V): CPU reads "0". GPIO IN1： echo 338 > /sys/class/gpio/export echo in > /sys/class/gpio/gpio338/direction cat /sys/class/gpio/gpio338/value GPIO IN2： echo 339 > /sys/class/gpio/export echo in > /sys/class/gpio/gpio339/direction cat /sys/class/gpio/gpio339/value GPIO-OUT CPU outputs "1": port outputs 3.3V.
CPU outputs "0": port outputs 0V. GPIO output is open-drain with 3.3V@10K pull-up. It can control 5V-12V devices (external pull-up required). GPIO OUT1： echo 335 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio335/direction echo 0 > /sys/class/gpio/gpio335/value echo 1 > /sys/class/gpio/gpio335/value GPIO OUT2 ： echo 334 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio334/direction echo 0 > /sys/class/gpio/gpio334/value echo 1 > /sys/class/gpio/gpio334/value | 11 | SIM | Image Added | Nano-SIM slot for 4G and 5G networks. | 12 | Debug Port | Image Added | Built-in USB to UART chip CH341, baud rate 115200bps.
