USB to TTL fully universal automatic downloader

Overview

Use CH340G and lead out common pins, and select 5V and 3V download modes through jumpers.
Using the type-c interface is more versatile, and you can download it with just a C port data cable.
If you use a chip such as Atmega328p LGT8F328P, directly short the pin header to 5V mode, as shown in the picture, and then RSTconnect the chip pins to the downloader DTRto achieve automatic downloading.
If you use a chip such as esp8266 or esp32, directly short the pin header to 3V mode, as shown in the picture, and then connect the chip ENor PDpin to the downloader DTR. For esp8266 and esp32, GPIO0ESP32-C3 is GPIO9connected to the downloader RTS, and automatic download
