ESP-01 Link V1.0 Programmer CP2104

This programming adapter connects an ESP-01 to the computer via USB. A CP2104 USB-to-serial converter handles the communication, an AMS1117 voltage regulator supplies the 3.3 V for the module. If the side button is pressed when plugging in, the ESP-01 starts in flash or programming mode, no wire jumper on GPIO0 is needed.
