What is it?

This is a multi purpose fused, FTDI USB to Serial converter with jumper selectable 3V3 or 5V0. The board has a 500mA 3V3 regulator on the bottom for the 3V3 option. This device is ideal for first experience with ESP8266 (wifi) HC-05, HC-06 (bluetooth). The device can plug into your breadboard as well, and is compatible with typical Sparkfun pinouts. It has two mounting holes and green indication LED's for TX and RX and comes with a free USB cable!

Why did you make it?

I made this because I wanted to be able to get experience with ESP8266 before implementing it in my embedded system. This way I could familiarize myself with the behaviour of the device and avoid troubleshooting during implementation. It has proven to be great for checking functionality of HC-06 bluetooth devices as well AND it plugs directly into the breadboard so you can talk to (or monitor) your micro controller!

What makes it special?

This board has everything I could personally need.

• True FTDI (works with Windows and Mac out of the box!)

• Fuse 0.5A fuse on the input of the USB connector

• Indication LED's on TX and RX

• Three connector types for ESP8266, HC-05 / HC-06 and for breadboard

• Jumper selectable 3V3 or 5V0 for use with all sorts of devices

• 2mm Mounting holes so you can mount it in a more permanent installation

Disclaimer

• It is not a development board for ESP8266. There is no reset button. It is purely a usb to serial converter.
• No ESP8266 or HC-0x included.
• I'm a hobbyist and this board is hand soldered. I do it as well as I can but it may be visible that this is done by hand :-). All boards are tested and guaranteed to work.
