Frequently Asked Questions

Q: What does the ESP-01 ESP8266 Breadboard Adapter do?

A: The ESP-01 ESP8266 Breadboard Adapter converts the ESP-01 / ESP-01S WiFi module's compact 2×4 pin header into a standard DIP breadboard-compatible footprint. This makes it easy to plug the module directly into a breadboard for rapid prototyping without soldering additional wires.

Q: Is this adapter compatible with both ESP-01 and ESP-01S modules?

A: Yes — the adapter is designed to work with both the original ESP-01 and the updated ESP-01S versions of the ESP8266 WiFi module, as both share the same 2×4 pin header configuration.

Q: Which microcontrollers can I use with this ESP8266 breadboard adapter?

A: The adapter uses a standard UART (TX/RX) serial interface, making it compatible with a wide range of microcontrollers including Arduino (Uno, Nano, Mega), Raspberry Pi, STM32, ESP32, and most other 3.3V/5V development boards.

Q: Does the ESP-01 WiFi module come included with the adapter?

A: Each order includes one DIP breadboard adapter board. The ESP-01 or ESP-01S module itself may be available as a separate selection — please check the variant options before ordering.
