ESP8266 dev board
Simple development board for ESP8266 with FTDI header.
Install the FTDI driver select the board as WeMos D1 mini in Arduino IDE and upload your sketch.
The advantage is that you don't neet to put GPIO 0 LOW in order to put the chip in flash mode. The NPN transistors will take care of this.
I revised the GERBER files because of the voltage regulator. In the first version i put an SOT-23 -3 pins voltage regulator and it did't provide enough mA. I change it with an AMS1117 and now everything is ok, as you can see in the pictures below.
The silkscreen contains the value of resistors and capacitors. For the pullup of I2C pins i used 3.3k resistors.
