Frequently Asked Questions

What is the default UART baud rate for the ESP-01M module, and how do I change it?

The default UART baud rate is 115200 bps. You can change it using AT commands like AT+UART_DEF. Send 'AT+UART_DEF=9600,8,1,0,0' to set it to 9600 bps with 8 data bits, 1 stop bit, and no parity. Ensure your serial terminal or microcontroller is configured to match the new baud rate after sending the command for successful communication.

How do I flash custom firmware onto the ESP-01M using the Arduino IDE?

To flash custom firmware, connect the module's GPIO0 pin to GND to enter bootloader mode, then power cycle it. In Arduino IDE, select 'Generic ESP8266 Module' as the board. Use a USB-to-serial adapter (3.3V logic) connected to the module's UART_TXD and UART_RXD pins. Select the correct COM port and upload your sketch. Remember to remove the GPIO0-GND connection after flashing to run the new firmware.

What power supply requirements does the ESP-01M have for stable operation?

The ESP-01M requires a stable 3.3V DC power supply within the range of 3.0V to 3.6V, connected to the VCC and GND pins. During RF transmission peaks, the module can draw significant current, so ensure your power source or regulator can deliver at least 300-400mA. Decoupling capacitors (e.g., 10uF and 0.1uF) placed close to the VCC pin are recommended to mitigate voltage drops and ensure stable Wi-Fi performance.
