DOIT ESP-M3 Ultra-Small ESP8285 Serial WiFi Module
The DOIT ESP-M3 is an ultra-compact serial-to-WiFi module based on the ESP8285 SoC, offering full compatibility with the ESP8266 platform. It operates at 3.3V and is ideal for embedding wireless connectivity into space-constrained IoT projects using AT commands or custom Arduino/ESP-IDF firmware.
Features
- ESP8285 Core: Features a 32-bit Tensilica L106 CPU with integrated 1MB SPI flash and full 802.11 b/g/n/e/i Wi-Fi support for Station, SoftAP, and SoftAP+STA modes.
- Ultra-Compact Form Factor: Measures just 20.5mm x 16mm, making it perfect for miniaturized, portable, or wearable electronics designs.
- High-Temperature Operation: Rated for an extended industrial temperature range from -40°C to +125°C, exceeding standard ESP8266 modules.
- Low Power & Fast Wake-Up: Achieves deep sleep currents as low as 10µA and can wake and transmit data packets within 2ms for battery-powered sensing.
- Rich Peripheral Set: Provides HSPI, UART, I2C, I2S, PWM, GPIO, and a 10-bit ADC for seamless integration with sensors and actuators.

The DOIT ESP-M3 module leverages the ESP8285 system-on-chip, a derivative of the popular ESP8266 with integrated 1MB flash. This design integrates a 32-bit Tensilica L106 processor capable of running at 80/160MHz, a full TCP/IP network stack, and a robust 2.4GHz Wi-Fi transceiver into a minimal 20.5mm x 16mm footprint. It is engineered for reliable serial data transparent transmission and can operate as a standalone application processor or as a Wi-Fi slave via UART AT commands.
Power management is a key feature, with deep sleep currents around 10µA enabling long-term deployment in field sensors and beacons. The module supports advanced Wi-Fi features including WPA/WPA2 security, SmartConfig for easy network provisioning, and over-the-air (OTA) firmware updates. Its extended -40°C to +125°C operating temperature range ensures stability in harsh industrial environments, automotive applications, or outdoor monitoring systems where thermal resilience is critical.
