I hate to connect ESP01 modules on breadboard so I've made simple devboard with programmer, some LEDs and switches on board.

Now I can easy test some IoT projects :)

Step 1: Step 1: Materials

You will need:

- ESP01 module

- CH340G

- Capacitors: 22uF x2 (SMDA), 100nF x 3 (0805), 68uF x 1 (SMDB), 22pF x 2 (0805)

- resistors (all 0805): 10k x 2, 2.2k x 1, 330R x 4

- 12MHz SMD crystal

- 4 mini SMD switches

- 4 leds SMD (0805)

- LM1117 SMD

- USB MINI socket

- some goldpins

Everything is on schematic.

Step 2: PCB.

I've made 2 PCB for this project. Unfortunately, I am not satisfied with the quality of these PCBs - everyone has something wrong, but I use my dremel and it works.

Step 3: Soldering

Step 4: Testing.

Test with server example from arduino IDE.

<p>looks great. Well done.<br>I love the esp8266-01, however it costs 1.80 USD while a Wemos D1 mini is 2.80 USD and for that you get the USB interface, the PSU and it is breadboard friendly + you get more i/o pins so it is a hard choice. (or rather, it isnt)<br>Doesn't impede the fact you made a hell of a nice pcb<br></p>
<div>Exactly, ESP-01 is veeery simple, anothers modules are better, but I have a couple of them and I want to use them. For simple temperature etc they are great.<br></div>
<p>sure, I fully understand. I have a couple too and still use them besides the Wemos and the NodeMCU... but I wouldnt buy a new one I think :-)</p>
<p>Nice build! I appreciate single sided PCBs without jumper wires, they are an art on its own :)</p>
<p>Thank You! It took me a couple of hours to plain it without jumpers :)</p>
<p>simple you say,</p><p>WOW</p><p>What a fricking beutiful build.</p><p>very nice. you can send me 1 if you can, haha </p><p>WannaDuino!</p>
