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. Review: Cheap ESP01's for projects. - Good to go & packed safely. Review: Amazing little gadget. Why the LEDs? - Given the set of AT commands you can throw at this thing, it can do some pretty cool things with just a little power. I have seen it: * Join a wireless LAN * GET from a website * POST to a website * Work with a PiCo * Work with Arduino IDE's Serial Monitor * Work with an obscure 8-bit microcontroller You can interface this thing with a USB-to-TTL bridging device and make it turn into a LAN server even. You can configure it that way to join your LAN automatically. And you get four in this package. It uses a fair amount of power when it is going full bore, but not compared to a router, for example. It can be set to sleep modes to conserve power. I think it is something like 70-90mA. Speaking of power, it would be nice if the LEDs could be completely shut off to avoid unnecessary consumption. This package is so small, desoldering seems kind of risky. ## 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 | #3,917 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 out of 5 stars 131 Reviews | | Included Components | 4 * ESP8266 WiFi Transceiver Module | | 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 Count | 1 | | RAM Memory Installed | 1 MB | | RAM Memory Technology | LPDDR3 | | Ram Memory Installed Size | 1 MB | | UPC | 608603912074 | | Unit Count | 4 Count | | Wireless Compability | 802.11b | ## Images ![Deegoo-FPV ESP8266 ESP-01 WiFi Modules, 4-Pack | 2.4GHz serial WiFi modules for Arduino-compatible boards, microcontrollers, IoT prototypes and wireless projects. - Image 1](https://m.media-amazon.com/images/I/713jtjcCbML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cheap ESP01's for projects. *by J***L on April 3, 2026* Good to go & packed safely. ### ⭐⭐⭐⭐ Amazing little gadget.

They use serial to connect to your Arduino or whatever, and use an extended AT command set to configure it, connect to WiFi and send/receive data. They also support AP mode so would be ideal for configuring your WiFi settings by first connecting your laptop/phone/etc to your project's own WiFi connection. If you're using this with the Arduino IDE there's a great library available on GitHub - search for ITEADLIB_Arduino_WeeESP8266 It's not breadboard friendly, but that's easily solved if you buy the adaptor, make one, or use Dupont wires. --- ## 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.bo/products/84114312-deegoo-fpv-esp8266-esp-01-wifi-modules-4-pack-2](https://www.desertcart.bo/products/84114312-deegoo-fpv-esp8266-esp-01-wifi-modules-4-pack-2) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-08-15*
