RTL8762C development board

1. The board is very simple, just add 3.3v power supply and CH340 serial port
. 2. The package of the module is measured manually, and there are some errors.
3. The pin definition is measured by a multimeter and has not been tested by the program
. 4. The pins of the module are all programmed. Round pad located on the back. It can be connected to the baseboard through flying wires
. 5. If external power supply and external serial port are used for programming, the AMS1117 and CH340 parts can be ignored.
6. It is packaged with USB-A and 0805, which is a personal preference (I only have a soldering iron on hand). Large packages are better. Welding
7. USB-A can be changed to type-c, which is also due to personal preference.
8. There are still some defects. USB-A is not centered up and down; the pin header is not symmetrical up and down, and it is not considered to match the breadboard; there is not enough VDD (VCC) , a few more can easily supply power to other external modules
9. CH340E can be changed to CH340C, which is easy to weld and the cost can be lower
. 10. The highest cost of the whole board is CH340. Those who know RTL8762 should understand
11. The diode next to UBUS uses Schott The voltage drop of the base diode is smaller, and ordinary diodes can also work. You can also replace it with a fuse, or directly short-circuit it.
