JOY-IT DEBO ESP8266-12F ESP8266 WiFi spájkovací modul SBC-ESP8266-12F

Embedded developers and IoT hobbyists can integrate reliable 2.4 GHz Wi-Fi connectivity into their custom PCB projects with the JOY-IT DEBO ESP8266-12F module. This compact SMD module, built around the Espressif ESP8266EX system-on-chip, offers a complete networking solution with a 32-bit Tensilica L106 microcontroller, 4 MB flash, and an onboard PCB antenna. Its castellated edge connections make it easy to solder directly onto a carrier board, enabling wireless communication for sensors, actuators, and control systems.

Key specifications

• Espressif ESP8266EX SoC with Tensilica L106 32-bit processor (80 MHz, up to 160 MHz)
• 4 MB SPI flash memory and 64 KB instruction RAM / 96 KB data RAM
• Wi-Fi 802.11 b/g/n, 2.4 GHz, with WEP, WPA/WPA2, TKIP, AES security
• 17 GPIO pins with UART, SPI, I2C, I2S, PWM, and ADC interfaces
• Operating voltage 3.0–3.6 V (3.3 V recommended), deep sleep current under 20 µA
• Supports Station, Access Point, and Station+AP modes; compatible with Arduino IDE, MicroPython, ESP-IDF, NodeMCU

Why choose it

The DEBO ESP8266-12F provides a cost-effective and well-documented path to add Wi-Fi to your designs. Its castellated pads ensure secure soldering for production or prototyping, while the onboard antenna eliminates the need for external components. With broad firmware support and low power consumption, it suits battery-powered devices and always-connected applications. The module's 4 MB flash allows over-the-air updates and complex sketches, giving you flexibility without extra hardware.

Ideal use cases

• IoT sensor nodes and home automation controllers
• Wearable devices and portable data loggers
• Wireless programming and debugging interfaces
• Smart lighting, relays, and environmental monitoring
• Educational projects and rapid prototyping

Good to know

The module operates at 3.3 V logic levels, so level shifting is required when interfacing with 5 V systems. It is delivered as a bare solder module without headers or a carrier board. For development, pair it with a USB-to-serial adapter and use the Arduino IDE or MicroPython for quick firmware upload. The PCB antenna is optimized for 2.4 GHz, and the module's compact footprint (approximately 24 x 16 mm) fits space-constrained designs.
