Product Description

ESP-07 WiFi Module (ESP8266)

Compact SMD Module with Ceramic Antenna and IPEX Connector

The ESP07 is a versatile WiFi module based on the *ESP8266* chip from Espressif [citation:1][citation:6]. This SMD-16 package module comes equipped with an onboard ceramic antenna and features a U.FL/IPEX connector for an external antenna, providing design flexibility for IoT and smart home projects [citation:1][citation:2][citation:8].

802.11 b/g/n WiFi Supports station, softAP, and station+softAP modes [citation:1][citation:6].
Dual Antenna Options - Onboard ceramic antenna + IPEX connector for external antenna [citation:1][citation:2].
Core Processor: ESP8266 Tensilica L106 32-bit MCU [citation:1][citation:4]
Clock Speed: 80 MHz (supports up to 160 MHz) [citation:6]
Flash Memory: 4MB (default) [citation:2][citation:3]

Troubleshooting

Module not responding:

  • Verify power supply is 3.0-3.6V with >300mA current capability.
  • Check CH_PD/EN is pulled HIGH to 3.3V.
  • Ensure GPIO0 is HIGH for normal boot, LOW for flashing mode [citation:3].

Wi-Fi not connecting:

  • Connect to 2.4GHz network only.
  • Check antenna connection.
  • Verify SSID and password in AT commands.
