Taojingchi serial port screen downloader

I. Description:
I recently got my hands on a Taojingchi serial port monitor, but during use, I encountered frequent restarts and failed to program. After consulting the official documentation, I found that the USB-TTL module's power supply was insufficient, causing the screen to restart repeatedly. The inability to program was due to the CH340N chip being counterfeit, resulting in high latency and data loss. The official recommendation is to use the CP2102 or FT232 chip, or even a genuine CH340. Here,
I'm using an IP5306 to power the serial port monitor, eliminating the need for an external power supply. The serial port chip used is the CH340T.
II. Main Functions:

USB to TTL,
supports 2A output power.
When not used for programming, it can be used as a power bank.
An additional backlight circuit allows it to be used as a lighting device.

III. Important
Notes: 1. The serial port chip must be genuine. Chips sold for a few dollars on Taobao have extremely low speeds, resulting in appalling programming speeds!
          2. The LED lighting section may have issues; it can be left unsoldered.
          3. The resistors and diodes at the programming port do not need to be soldered; soldering is only required when programming the microcontroller.
