ESP32 & ESP8266 WiFi Modules

ESP32 & ESP8266 WiFi Modules in Pakistan

Build WiFi and Bluetooth projects with ESP32 and ESP8266 boards from MREECO Electronics, Hall Road Lahore. This page has NodeMCU, Wemos D1 Mini, ESP32 DevKit, ESP32-CAM, ESP32-C3 Super Mini, ESP-01 and ESP-12 modules, plus the shields, adapters, relay boards and cables you need to program and power them. Students, hobbyists and engineers use them for IoT sensors, home automation, web servers and wireless robots. We deliver across Pakistan.

Why choose ESP32 / ESP8266?

• Built-in WiFi on every board, and Bluetooth on ESP32.
• Programmable from the Arduino IDE, MicroPython or ESP-IDF.
• ESP32 has a dual-core processor and many more pins than ESP8266.
• Low cost compared with most other IoT boards.
• Over-the-air (OTA) firmware updates without a USB cable.

Module types

• ESP32 DevKit / Wroom 32D / 38-pin NodeMCU-32S: general-purpose WiFi + Bluetooth boards.
• ESP32-CAM: ESP32 with an OV2640 camera for streaming and surveillance.
• ESP32-C3 Super Mini: small, low-power board with WiFi and BLE.
• LOLIN32 and D1 Mini ESP32: compact ESP32 boards, some with a LiPo battery connector.
• T-Call ESP32 SIM800L: ESP32 with a GSM module for SMS and calls.
• NodeMCU V2 / V3, Wemos D1 Mini, Wemos D1 R1: ESP8266 boards with USB for easy programming.
• ESP-01, ESP-01S, ESP-07, ESP-12E / 12F: bare ESP8266 modules for compact or custom designs.

Common applications

• IoT sensor nodes for temperature, humidity and gas.
• Home automation with WiFi relays and MQTT.
• Local web dashboards and web servers.
• WiFi controlled robots and cars.
• Camera streaming, GSM alerts and data logging.

How to choose

1. Need Bluetooth or lots of pins? Choose ESP32. WiFi only and a tight budget? ESP8266 is enough.
2. Need a camera? Choose ESP32-CAM.
3. Need the smallest size or low power? Choose ESP32-C3 Super Mini or Wemos D1 Mini.
4. New to IoT? Start with a NodeMCU board or the IoT NodeMCU Starter Kit, which have a built-in USB programmer.

Frequently asked questions

What is the difference between ESP32 and ESP8266?
ESP8266 has WiFi only, a single core and fewer pins. ESP32 adds Bluetooth, a dual-core processor, more GPIO pins and more peripherals, so it suits bigger projects.

Which ESP board is best for beginners?
A NodeMCU or an ESP32 DevKit board. They have a USB port, so you can program them from the Arduino IDE without extra hardware.

Can I program an ESP32 with the Arduino IDE?
Yes. Install the ESP32 board package in the Arduino IDE, select your board and upload as you would on an Arduino.

How do I program the ESP-01 module?
The ESP-01 has no USB port. Use a USB to ESP8266 serial adapter, or an ESP-01 programmer, and power it with 3.3V.

What is the operating voltage of ESP boards?
The chips run at 3.3V and their GPIO pins are not 5V tolerant. Development boards have an on-board regulator, so you can power them from USB (5V).

Can I run an ESP board on battery?
Yes. Use a LiPo or 18650 cell with a battery shield or a board with a LiPo connector, such as the LOLIN32. Deep-sleep mode helps the battery last longer.

Do you deliver outside Lahore?
Yes, all over Pakistan. You can also visit our shop on Hall Road, Lahore, or call 0342-9472107 to confirm stock before ordering.
