ESP-01 ESP8266 Serial Wifi Wireless Transceiver Module

The ESP-01 ESP8266 Serial WiFi Wireless Transceiver Module is a compact and versatile module for IoT projects. Here are its key features and specifications:

  Features:  

• Compact size: 25mm x 15mm.
• Simple pin connections with standard 2.4 pin headers.
• Uses serial TX/RX for sending and receiving Ethernet buffers.
• Supports serial commands for querying and changing configurations of the WiFi module.
• Ideal for hobbyists and IoT experimentation.
• Easy way to connect to the internet via WiFi with any microcontroller platform.
• Can be used with Arduino using AT commands.
• Supports open TCP/IP connections without the need for a TCP/IP stack in the microcontroller.
• High degree of on-chip integration, minimal external circuitry required.
• Supports APSD for VoIP applications and Bluetooth co-existence interfaces.
• Self-calibrated RF, works under all operating conditions, no external RF parts required.
• Extensive community support and resources available.

  Specifications:  

• Wi-Fi Direct (P2P), soft-AP.
• Integrated TCP/IP protocol stack.
• Integrated TR switch, balun, LNA, power amplifier, and matching network.
• Integrated PLL, regulators, DCXO, and power management units.
• Integrated low-power 32-bit CPU for application processing.
• Supports SDIO 1.1/2.0, SPI, and UART interfaces.
• Supports STBC, 1 - 1 MIMO, 2 - 1 MIMO.
• Supports A-MPDU & A-MSDU aggregation and 0.4ms guard interval.
• Wake up and transmit packets in < 2ms.
• Standby power consumption of < 1.0mW (DTIM3).
• Output Power(dBm): 19.5.
• Dimensions: 25mm (L) x 15mm (W) x 1.33mm (H).

Note: The ESP8266 Module requires an external Logic Level Converter as it is not capable of 5-3V logic shifting. Do not power it directly from a 5V dev board.

  Package Includes:  

• 1 x ESP-01 ESP8266 Serial WIFI Wireless Transceiver Module
