Esp8266 Esp12 Breakout Program Jig

Introduction: Esp8266 Esp12 Breakout Program Jig

Every time i wanted to use the ESP8266 ESP12 in a project i hated that it didnt fit on a breadboard so you could connect to it, and you also had to wire it to an FTDI serial module and a button to pull GPIO0 to gnd to program it.

So to avoid that in the feature i decided to make programming jig where i can plug my breadboard wires into.

I first made an eagle component of the ESP8266 ESP12 breakout board and the designed a PCB in eagle where i connect an FTDI and plug in the ESP8266 ESP12, with an on off switch for the ESP, and a button for reset and one for programming. Then later designed an 3D-printed case for it.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Components/parts List/tools


1x ESP8266 ESP12 or ESP12E

1x ESP8266 ESP12 breakout

1x USB FTDI module

1x ams1117 3.3 volt regulator

1x 3 pin pcb sliding switch

2x tact button

1x 6 pin male pin header

4x 8 pin female pin header

50x50 mm single sided PCB

an leg from an resistor to make an bridge

Tools needed.

Soldering iron

Cnc router to make pcb or another way to make home made pcb's

3D-printer to make the case

Step 2: PCB Files

Ii designed the pcb in eagle

Step 3: Make Pcb and Solder It

I went to my local hackerspace HAL9K ( where we have an cnc router that is perfect to make PCB's on, it needs gcode witch i made with the ULP script PCB-GCODE

the voltage regulator need to sit on the under side of pcb because of it is an smd component.

Step 4: 3D Print Case

I didnt like the bare PCB so i decided to make a case for it. I designed the case in a program called Designspark Mechanical.

I printed the extendion for the buttons in different colurs to make it posible to identify the reset and program button, where the blue is the program button and the red is the reset button, The white part is the on/off switch for the ESP.

Step 5: Begin Prototyping

Now it is easier to prototype with the ESP8266 ESP12

Let me know if you have any questions or you find this instructable use full.

    Hey there,

    It looks awesome. i just have one doubt. Don't we need to convert the logic levels of Rx and Tx from 5V to 3.3V ?
