Designed for seamless Arduino integration, it offers 115200 bps UART communication and minimal external circuitry, making it ideal for versatile IoT applications requiring efficient wireless networking. ## 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. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. Specifications: Serial/UART baud rate: 115200 bps Input power: 3.3V I/O voltage tolerance: 3.6V Max Flash Memory Size: 1MB (8Mbit) WiFi security modes: WPA, WPA2 Tip:The CH_PD pin must be set high for it to run independently of the FTDI. Review: Small IoT device with lots of functionality. - I love ESP8266 devices. I have about a dozen in my house serving different purposes. These are so small they can fit anywhere, and use very little power. I load ESP Easy on the IoT device, and use them for thermometers, motion sensors, door (reed) switches, and relays to turn on/off lights. The possibilities are endless! Review: Under Rated For 2026 - Highly underrated in 2026 for esp-now us with other boards like pi picos or yd-rp2040's. Great value for money. Fast connection and speed. They are tiny and weigh almost nothing. Their functionality is where I think they are underacted as using them as a module vs a mcu. Great quality. Just put in an order for more and and order for the S variants. ## Features - ESP8266 has powerful on-board processing and storage capabilities - Support 3 modes: AP, STA, AP + STA ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #89 in Computer Networking Transceivers | | Customer Reviews | 4.2 out of 5 stars 234 Reviews | ## Images ![3pcs ESP8266 ESP-01 Serial WiFi Wireless Transceiver Wireless Module Development Board LWIP AP+STA Compatible with Arduino - Image 1](https://m.media-amazon.com/images/I/61TmTcwBlML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small IoT device with lots of functionality. *by K***H on August 3, 2019* I love ESP8266 devices.

The multi-pack is useful for small Wi-Fi projects and for keeping backup modules available. I am giving four stars rather than five because I have not done long-term testing on every board in the pack. I plan to keep testing them in future projects and will update this review if anything changes. ## Frequently Bought Together - HiLetgo 3pcs ESP8266 ESP-01 Serial WiFi Wireless Transceiver Wireless Module Development Board LWIP AP+STA Compatible with Arduino - DSD TECH HM-10 Bluetooth 4.0 BLE iBeacon UART Module with 4PIN Base Board for Arduino UNO R3 Mega 2560 Nano - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/17420903-3pcs-esp8266-esp-01-serial-wifi-wireless-transceiver-wireless-module](https://www.desertcart.at/products/17420903-3pcs-esp8266-esp-01-serial-wifi-wireless-transceiver-wireless-module) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-29*
