Interface isolation board for UltraLink

This is an interface isolation board only for UltraLink, and testing has shown it can stably reach 10Mbps. Similar designs can also be used as a reference.
The isolation board only exposes 5V, 3V3, TX, RX, SWDIO, SWCLK, and GND interfaces. The output interfaces use standard ST-TAG interfaces and custom 6-pin sockets (to reduce size).
The isolation chip is the CA-IS3762HN (4 transmit, 2 receive) from Chuantu Microelectronics, and the isolation power supply is the B0503XT-2WR3 from Mornsun. UltraLink provides a separate 3V3 output to power the CA-IS3762HN and a separate 5V output to power the B0503XT-2WR3. The B0503XT-2WR3 has a maximum output current of 600mA and can power the target board. When the target board has an independent power supply, the output can be cut off via a sliding switch.
