What's it
A 3.3V USBToUART converter support 400mA+ current. Program ESP8266/ESP32 module just like NodeMCU. It has small size and we make it breadboard friendly. You can also use the flasher to programming ESP32 without pushing flash button.
ESP Flasher Rev6 - USB Type-C and CH340
ESP Flasher Rev5 - USB Type-C and CP2104
ESP Flasher Rev4 - Micro USB
Why did you make it?
The converter supports 400mA+ current. It's good for programming ESP8266 and ESP32 module
For program with Arduino IDE, the circuit does the trick for auto reset.

|---|---|
| VCC | VCC |
| GND | GND |
| TXD | RXD |
| RXD | TXD |
| RST | RST |
| GPIO0 | GPIO0 |
| CH_EN | CH_EN or CH_PD |
For ESP32
| flasher pin | ESP32 pin |
|---|---|
| VCC | VCC |
| GND | GND |
| TXD | RXD |
| RXD | TXD |
| RST | EN |
| GPIO0 | GPIO0 |
| CH_EN | Not wire |
