Tutorial: How to Use TTGO T-Beam ESP32 Module

The TTGO T-Beam ESP32 is a multifunction module ideal for IoT and remote monitoring projects. Suitable for beginners and intermediates.

What you need

• TTGO T-Beam ESP32 Module
• Arduino IDE
• USB Cable
• 10kΩ Resistor
• LiPo Battery (optional)

Steps

1. 1. Download and install the Arduino IDE.
2. 2. Connect the module to your computer with the USB C cable.
3. 3. Select ‘ESP32 Dev Module’ as board in the ‘Tools’ menu.
4. 4. Load the ‘Blink’ example to verify the connection.
5. 5. Connect to the module WiFi: ‘ttgo’ / ‘TTGO123’.
6. 6. Connect pin D2 to the TX of your sensor.
7. 7. Add the ‘Adafruit_LSM9DS1’ library for the accelerometer.
8. 8. Run a sample code to read sensor data.

Example code

```
#include <Adafruit_LSM9DS1_U.h>

Adafruit_LSM9DS1_Unified lsm;

void setup() {
  Serial.begin(115200);
  lsm.begin();
}

void loop() {
  if (lsm.testConnection()) {
    Serial.println("Connection OK");
    float x, y, z;
    lsm.getVector(&x, &y, &z);
    Serial.printf("Accel: x=%2.2f, y=%2.2f, z=%2.2fn", x, y, z);
  }
}
```

Frequently asked questions

How can I connect to the WiFi module?
Use the default configuration ‘ttgo’ / ‘TTGO123’ or set your WiFi details.

What is the difference between D2 and D3?
D2 is TX, D3 is RX. Use D2 to send data, D3 to receive it.

Can I use another library for the accelerometer?
Yes, but make sure it is compatible with ESP32.

Does the module work with AA batteries?
No, use a 3.7V LiPo battery or USB power.
