Overview
- The ESP-01S (ESP-01 Upgrade) WiFi module was developed by Ai-Thinker Technology Company. The ESP-01S in DIP package, unique plug-in package design, it can be flexible access to existing products, especially for automation, large-scale, low-cost modern production methods, easy to apply to a variety of things networking hardware terminal occasions.
Features:
- 802.11b/g/n Wi-Fi SOC module
- Low power 32-bit CPU, can also serve as the application processor
- Up to 160MHz clock speed
- Supports UART/GPIO
- DIP-8 package for easy welding
- Integrated Wi-Fi MAC/BB/RF/PA/LNA
- Deep sleep current as low as 20uA
- Embedded lwIP protocol stack
- Supports STA/AP/STA + AP operation mode
- Support Smart Config/AirKiss technology
- UART baudrate up to 4Mbps
- General AT commands can be used quickly
- Supports remote firmware upgrade (FOTA)
- Power Supply: Voltage 3.0V ~ 3.6V, Current >300mA
- SPI Flash: 8Mbit
Note:
- This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolerant. Connect RX or TX on 5V Arduino will destroy this module. You must use a logic level converter, or a 3.3V Arduino.
- The 3.3V supply on the Arduino Uno has inadequate current capability to power this module. You must provide a separate, higher 3.3V supply(about 300mA or better).
Package included:
1 x Genuine AI-Thinker ESP8266 ESP-01S Wireless Remote Serial WiFi Module
