FL-M1S ESP8266 Serial-to-Wi-Fi Module
The FL-M1S is an ESP8266-based TTL serial-to-Wi-Fi module, enabling rapid IoT integration for microcontrollers. It provides a complete 802.11 b/g/n Wi-Fi solution with a high-power +19.5dBm PA, soft-AP, and station modes, compatible with Arduino IDE and AT command firmware.
Features
- Based on the ESP8266 SoC with integrated 32-bit RISC processor, Wi-Fi MAC/BB, RF front-end, and TCP/IP stack.
- High-power +19.5dBm output in 802.11b mode for extended wireless range exceeding 100 meters.
- Ultra-low power operation with <10µA deep sleep leakage current for battery-powered IoT nodes.
- Simple TTL serial (UART) interface for easy integration with Arduino, STM32, or other 3.3V MCUs.
- Supports Wi-Fi station, soft-AP, and Wi-Fi Direct (P2P) modes for flexible network topologies.

The FL-M1S module encapsulates the full capabilities of the Espressif ESP8266 chip into a compact, surface-mountable form factor. It integrates the RF switch, balun, power amplifier, low-noise amplifier (LNA), and matching network, requiring minimal external components for a functional Wi-Fi node. The module operates from a 3.3V supply and can deliver a robust +19.5dBm transmit power, making it suitable for applications requiring extended range.
Beyond its role as a simple serial-to-Wi-Fi bridge using AT commands, the onboard Tensilica L106 processor can run custom firmware, allowing the module to function as a standalone IoT controller. With integrated SPI, I2C, I2S, and multiple GPIOs, it can directly interface with sensors and peripherals, reducing system complexity and BOM cost for connected device designs.
