| This moduel is an USB adpater / programmer for ESP8266 moduels of type ESP-01. |
| It is conveniently fitted with a 2x4P 2.54mm female header to plug the ESP01 and configure or run it right away. |
| The module is based on the USB-UART bridget CH340 from WCH which is compatible with all platforms. |
|
for an usage with Arduino ESP8266 platform and Arduino IDE it is necessary to switch manually the GPIO0 state for working mode, in order to get a fully automatic upload it is most likely possible, to assign an unused control line from CH340 to driver the GPIO0 line (probably at the cost of a necessary logic inversion), refer to the CH340 datasheet and most important to the NodeMCU V0.9 which use the CH340 and already implements this solution.
