## Overview

The HiLetgo ESP8266 ESP-01 is a compact, highly integrated WiFi transceiver module featuring dual AP+STA modes, 1MB flash memory, and low-voltage operation at 3.3V. Designed for seamless integration with Arduino and other microcontrollers, it offers powerful onboard processing and minimal external circuitry, making it ideal for versatile IoT applications requiring fast, reliable wireless connectivity.

## 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 CHPD pin must be set high for it to run independently of the FTDI.

Review: 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.
Review: 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!

*by R***T on 4 April 2024*

I happened to pick the bad one to start my project. Just my luck!. After spending hours troubleshooting my setup, I found out that it was bad. I was not getting an AT OK back. After swapping it out, the other 2 worked fine. They are also doing their jobs quite well. They are very small units so working with them is tricky.
