Introduction: Simple ESP-01 Testboard
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 :)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: Materials
You will need:
- ESP01 module
- 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.
