Designed for 3.3V input, these modules support multiple network modes (AP, STA, AP+STA) and provide a robust, low-power solution for seamless wireless connectivity in IoT and embedded projects. ## Description ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.Specifications:Serial/UART baud rate: 115200 bpsInput power: 3.3VI/O voltage tolerance: 3.6V MaxFlash Memory Size: 1MB (8Mbit)WiFi security modes: WPA, WPA2Package Including4 * ESP8266 Wifi Transceiver Module Version II---How to use??Version II(All IO serial port version) Note:The power supply should be 3.3v!!about this version II,if you want to enter into AT command by FLASH boot,just need connect CH-PD pin with VCC pin or pull up resistor to keep high-level.(Sometimes without pulling up the resistor,there's no data on the serial port)The other three pins don't need to connect anything,if you connect them with VCC pin and failed restart,you shouldn't connect them.When GPIO0 is high-level,it means FLASH booting.When GPIO0 is low-level,it means upgrading the system.At this moment,you can upgrade the internal firmware by serial port. And RST(GPIO16)can be used to reset the external hardware.P.S.Different test systems may use different connecting ways,so you need choose the best connecting ways by yourself.Hereby we recommend one connecting way to connect esp01 module with serial port TTL tools.:After welding a 4.7k resistance between CH-PD pin and VCC pin. it needs connect UTXD,GND,VCC and URXD pin with USB-TTL(TXD and RXD need keep cross-linking)to test. ## Features - Note: The item only supports 3.3V, please don't use 5V! - Model: Esp-01.Compatible with Arduino. Support 3 modes: AP, STA, AP + STA - ESP8266 is a WiFi enabled Microcontroller – Arduino ready - Updated version ESP-01,with stronger signal - Complete and self-contained Wi-Fi networking solution ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H1W6DJZ | | Best Sellers Rank | #4,931 in Single Board Computers (Computers & Accessories) | | Brand | Deegoo-FPV | | Built-In Media | 4 * ESP8266 WiFi Transceiver Module | | Connectivity Technology | Wi-Fi | | Customer Reviews | 4.3 4.3 out of 5 stars (131) | | Manufacturer | Deegoo-FPV | | Memory Storage Capacity | 1 MB | | Mfr Part Number | 8541549612 | | Model Name | ESP-01 | | Model Number | 8541549612 | | Number of Items | 4 | | Operating System | Linux | | Processor Brand | Espressif | | Processor Count | 1 | | RAM Memory Installed | 1 MB | | RAM Memory Technology | LPDDR3 | | UPC | 608603912074 | | Unit Count | 4 Count | | Wireless Compability | 802.11b | ## Product Details - **Brand:** Deegoo-FPV - **Connectivity Technology:** Wi-Fi - **Memory Storage Capacity:** 1 MB - **Model Name:** ESP-01 - **Ram Memory Installed Size:** 1 MB ## Images ![Deegoo-FPV ESP8266 ESP-01 WiFi Modules, 4-Pack - Image 1](https://m.media-amazon.com/images/I/713jtjcCbML.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/84114312-deegoo-fpv-esp8266-esp-01-wifi-modules-4-pack](https://www.desertcart.us/products/84114312-deegoo-fpv-esp8266-esp-01-wifi-modules-4-pack) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-31*
