This implements the \"auto reset\" circuits of most ESP32 dev boards. You can run things like esp-idf's `make flash` or flash code from the Arduino IDE without having to hold down any buttons.\n\nConnect `EN`, `RX`, `TX`, `IO0`, and `GND` to their respective pins on the ESP32 (don't forget to swap the `RX` and `TX` pins!) and make sure you have the Silicon Labs CP210x driver installed on your OS.\n\nYou can order this PCB on [OshPark](https://oshpark.com/shared_projects/q04gDLKl)\n\n## Required Parts\n\n(All resistors and capacitors are size 1608 metric)\n\n| Label | Description |\n| --- | --- |\n| U1 | CP2102N |\n| R1 | 1 kOhm |\n| R2 | 10 kOhm |\n| R3 | 22.1 kOhm |\n| R4 | 10 kOhm |\n| R5 | 47.5 kOhm |\n| C1 | 4.7 uF |\n| C2 | 0.1 uF |\n| C3 | 4.7 uF |\n| C4 | 0.1 uF |\n| Q1 | MMBT2222L transistor (SOT-23 package) |\n| Q2 | MMBT2222L transistor (SOT-23 package) |\n\n## Images\n\n### Schematic\n![schematic](images/schematic.png)\n\n### PCB Layout\n![pcb](images/pcb.png)\n\n### Assembled\n![assembled](images/assembled.jpg)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbschwind%2Fesp32-autoflasher","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbschwind%2Fesp32-autoflasher","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbschwind%2Fesp32-autoflasher/lists"}
