By using this device it eliminates the need to build circuit just to upload code directly to device that does not have built-in TTL to USB like ESP32 or ESp8266. The adjustable output voltage of 3V to 5V is great to have so no I no longer need to build my own voltage regulator, which saves time building it just to upload a code. I will recommend this tool.
