What is included in this ESP-01 kit?

This kit includes an ESP-01 ESP8266 WiFi Transceiver Module and a matching USB adapter board for easy programming.

How much flash memory does this upgraded ESP-01 module have?

This upgraded version features 1MB of flash storage, giving you extra space for complex custom scripts and web servers.

Can I program the ESP-01 directly using a computer USB port?

Yes! The included USB adapter board lets you plug the ESP-01 directly into your computer's USB port for seamless code flashing via Arduino IDE.

What is the operating voltage of the ESP-01 module?

The ESP-01 operates strictly on 3.3V DC. Connecting it directly to a 5V source without regulation will damage the module.

Where can I buy the ESP-01 WiFi Module Kit in Bangladesh?

You can order it directly from KathalTech (kathaltech.com) with reliable delivery across Bangladesh.

Verified Comments Listing

The ESP-01 ESP8266 Serial WiFi Wireless Transceiver Module with USB Adapter Kit combines one of the world's most popular ultra-compact IoT SoC modules with a dedicated USB programming adapter, giving you an immediate plug-and-play development experience.

The ESP-01 module features a powerful integrated 32-bit microcontroller, a complete TCP/IP protocol stack, and an upgraded 1MB flash storage chip (doubling legacy 512KB variants) to easily host standalone custom software, web servers, or wireless serial bridges. Communication is handled smoothly via standard AT commands or custom code written using the Arduino IDE.

This kit includes the essential ESP01 USB Adapter Board, equipped with a built-in USB-to-serial chip and automatic download capabilities. This eliminates the traditional frustration of juggling manual jumper wires and button presses during code uploads.

Key Features & Benefits:

All-in-One Development Kit: Includes both the ESP-01 WiFi module and a dedicated USB programmer adapter.
Upgraded 1MB Flash Memory: Provides ample space for firmware, custom user scripts, and lightweight web pages.
Plug-and-Play USB Programming: The adapter board enables direct connection to your PC for fast code flashing and serial debugging.
Integrated TCP/IP Stack: Allows microcontrollers to connect to Wi-Fi networks and interact with web APIs easily.
Versatile Operating Modes: Works as a standalone application processor or as a wireless serial bridge for other MCUs (like Arduino Uno or Mega).

Applications:

Internet of Things (IoT) sensor nodes and smart home systems
Wi-Fi enabled remote telemetry and data logging
Home automation and appliance control
Standalone web servers and wireless serial bridges

Engineering Tip: The ESP8266 can draw burst currents up to 300mA during active RF transmission. Ensure your power source is stable and consider placing a $10\mu\text{F}$ to $100\mu\text{F}$ decoupling capacitor across the VCC and GND pins if powering from external sources to prevent voltage sags or reboots.
