What is the operating voltage of the ESP-05?
The ESP-05 operates at 3.3V logic. Connecting it to 5V logic may damage the module. Use a level shifter if interfacing with 5V microcontrollers.
What payment options are available for the WiFi Serial Transceiver Module ESP8266 ESP-05?
You can pay using UPI, credit/debit cards, or Cash on Delivery (COD). All payment options are available across India.
How do I get started with the ESP-05?
Connect VCC and GND to 3.3V, then connect TX/RX to your microcontroller's UART pins. Use AT commands via a serial terminal to configure WiFi. Our AI build companion provides wiring diagrams and sample code.
