Introduction: Portable IoT Display
This instructables show how to use a 2 inches LCD and ESP32 to make a portable IoT Display.
TTGO T7 V1.0
2 inches IPS LCD
D-Ring Locking Carabiner Clip Keychain
Step 1: 3D Print Case
Please download and print the case at thingiverse:
Step 2: Soldering Work
Follow the LCD datasheet connect the pins. Please read through the datasheet before connection especially if you are not ordered same LCD model.
Here are the connection summary:
ESP32 -> LCD GND -> Pin 1 GND -> Pin 2 LED K 3v3. -> Pin 4 Vcc -> 20 Ohm -> Pin 3 LEDA GPIO 27 -> Pin 7 D/C GPIO 5 -> Pin 8 CS GPIO 18 -> Pin 9 SCK GPIO 23 -> Pin 10 MOSI GPIO 33 -> Pin 11 RST
Step 3: Seal Wires
Use some tapes to seal the soldered wires and exposed pins.
Step 4: Assembly
Please follow the video to assembly.
Step 5: Program
Download and install Arduino IDE if you are not yet do it:
Follow the Installation Instructions to add ESP32 support if you re not yet do it:
Download latest Arduino_GFX libraries: (press "Clone or Download" -> "Download ZIP")
Import libraries in Arduino IDE. (Arduino IDE "Sketch" Menu -> "Include Library" -> "Add .ZIP Library" -> select downloaded ZIP file)
Compile & Upload
- Connect the device with USB cable
- Open Arduino IDE
- Open ESPWiFiAnalyzer sample code ("File" -> "Example" -> "Arduino_GFX" -> "ESPWiFiAnalyzer")
- Press Arduino IDE "Upload" button
Step 6: Enjoy!
This 2 inches IoT display not only a simple ESP WiFi Analyzer, ESP32 have much more possibilities. It's time to use your imagination to develop your unique IoT device!
