KEYESTUDIO ESP8266 ESP-12F CH340G WiFi Module Board for Arduino NodeMcu +1M USB Cable /Development Board /Compatible with Networking

This Keyestudio ESP8266 ESP-12F development board is a versatile, Wi-Fi-enabled microcontroller designed for IoT projects, smart home automation, and wireless networking. It is an ideal choice for South African students, educators, and makers looking to build standalone network controllers or add wireless capabilities to existing Arduino-compatible setups. The package includes a convenient 1-metre Micro USB cable to get your projects powered and programmed straight away.

High-performance 32-bit processing

The board is powered by the Tensilica L106 ultra-low-power 32-bit micro MCU, which supports adjustable clock speeds of 80MHz and 160MHz. It features a 16-bit Lite mode and supports Real-Time Operating Systems (RTOS) for efficient multitasking in complex coding projects.

Integrated wireless networking

Built on the Ai-Thinker ESP8266-12F module, this board features an onboard curved antenna alongside integrated Wi-Fi MAC, baseband, RF, PA, and LNA components. It functions as a standalone network controller or can be used to add wireless connectivity to your existing hardware.

Dual-mode Wi-Fi capabilities

Supporting the 802.11 b/g/n wireless standard, the module can operate in both Station (STA) and Access Point (AP) modes. The built-in TCP/IP stack allows you to configure a socket and supports standard TCP/UDP Server and Client protocols.

Simple power and programming

The board operates at DC 5V and is powered and programmed via a standard Micro USB port, requiring a 2A current supply. A 1-metre Micro USB cable is included in the box to ensure you can connect to your computer immediately.

Versatile serial communication

The serial port supports a wide range of baud rates from 1200 bps up to 115200 bps, with configurable data bits, stop bits, and parity checks. Wireless transmission speeds range from 110 bps to 460800 bps for flexible data transfer.

Onboard physical controls

For easy debugging and configuration, the board is equipped with a dedicated physical reset button and a multi-function KEY button. It also features a single analog input pin (A0) for connecting sensors and is rated to operate in temperatures ranging from -40C to +125C.
