MSP430G2553_NANO, with downloader

Because the school curriculum requires the G2553 microcontroller, but the price on Taobao is often 50-60 RMB, I decided to make my own Nano-sized G2553 core board.
 
The board's functionality has been roughly verified (pointer LEDs).
 
Note 1: Important! Important! Important!!! When downloading, you need to connect it as shown in the diagram below: connect the CH340's TXD to P1.5 using a jumper (white in the diagram), connect the RXD to P1.1 using a jumper (black in the diagram), and directly connect the remaining TCK and TDIO pins with jumper caps. Only in this way can you download. Why not just change the circuit diagram to this? Because I need to use serial communication, so this is the only way to do it properly during download, even if it's a bit of a compromise.
Note 2: Download the software using https://github.com/gbhug5a/MSP430-BSL, and use the command BSLDEMO-2.01c.exe -cCOM12 -i program.txt.
Note 3: To generate a program file with the .txt extension, you need to install the GCC toolchain in CCS. For subsequent steps, please search online.
Note 4: When soldering, it is recommended to insert the pin headers into the breadboard or perforated board first, and then place the board on top for soldering. Otherwise, the outward tilting of the pin headers caused by soldering may prevent insertion into the front panel/perforated board.
Note 5: If you have any questions or find any errors, please point them out in the comments.
