ESP-01S ESP8285 Serial to WiFi Wireless Module 1MB

The ESP-01S ESP8285 Serial to WiFi Module is an ultra-compact, industrial-grade wireless transceiver designed to bring high-speed internet connectivity to your microcontrollers. This advanced version utilizes the ESP8285 chip, which integrates a powerful 32-bit MCU with 1MB of built-in flash memory directly on the silicon. This integration eliminates the need for external flash chips, resulting in superior reliability, better thermal performance, and a highly stable connection for demanding IoT applications.

Perfect for smart home automation, remote sensor networks, and DIY robotics, this module communicates seamlessly via standard UART serial interfaces using simple AT commands. It is fully compatible with the Arduino IDE, ESP8266 SDK, and MicroPython, allowing developers to program it directly as a standalone microcontroller. With its optimized low-power architecture, the ESP-01S is ideal for battery-operated devices requiring deep-sleep capabilities and efficient wireless transmission.

Features:

• Integrated ESP8285 Processor: Combines a 32-bit RISC core with 1MB of on-chip flash memory for enhanced reliability.
• Industrial-Grade Stability: Designed to operate reliably under varying temperature conditions with low-power consumption.
• Onboard PCB Antenna: Features a high-efficiency integrated trace antenna for stable 2.4GHz signal reception.
• Standard Serial Interface: Communicates via UART with a default baud rate of 115200 bps, making it easy to interface with Arduino, STM32, and Raspberry Pi.
• Multiple Low-Power Modes: Supports deep sleep, standby, and active modes to conserve battery life in remote sensor nodes.
• Compact Form Factor: Tiny 2x4 pin layout easily fits into breadboards (via adapters) and custom PCBs.
