Rasberry I Zero W have BCM43143, WiFi + Bluetooth 4.1 + BLE (Bluetooth Low Energy), same as Raspberry Pi 3.
Sonoff Basic is a WiFi enabled smart switch that provides smart home control in an affordable way. It can be connect to a wide range of appliances to switch them remotely. Just install eWeLink app in your smart phone and power up your Sonoff Basic WiFi electrical switch, follow a couple of instructions and turn a Light / Fan / TV and lot more device ON/OFF just tapping on your smart phone screen. It is just a first level,
This is the famous NodeMCU which is based on ESP8266 WiFi SoC. This is version 3 and it is based on ESP-12E (An ESP8266 based WiFi module). NodeMCU is also an open-source firmware and development kit that helps you to prototype your IoT(Internet of Things) product within a few LUA script lines, and of course you can always program it with Arduino IDE.
Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP).
The Arduino Nano v3 in Pakistan is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. The Nano was designed and is being produced by Gravitech.
Digital Infrared Temperature Sensor for Arduino MLX90614 GY-90614 Module.This is a MELEXIS MLX90614ESF-BAA-000-TU-ND non-contact infrared thermometer for use with Arduino, or any microcontroller that can communicate with it through it’s I2C interface.
The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
The Arduino ADK is a microcontroller board based on the ATmega2560. It has a USB host interface to connect with Android based phones.
The STM32 Nucleo-64 boards provide an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontrollers, choosing from various combinations of performance, power consumption and features.
This is FS1000A 433mHz Tx RF Radio Module. This RF module comprises of an RF Transmitter and an RF Receiver. The transmitter/receiver (Tx/Rx) pair operates at a frequency of 433 MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.
Now with this low cost version of Mega compatible with CH340 (USB to UART chip), you have more reasons to get this board instead of UNO :). And Mega compatible board is fully compatible with Arduino Mega2560 R3,
Arduino Uno R3 SMD Micro USB in Pakistan has 14 digital input/output pins (6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a Micro USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller
NodeMCU is famous for the ESP8266E module with LUA programming language. Now this is more powerful NodeMCU with ESP32 on it.ESP32 is the big brother of ESP8266. It comes with dual core 32-bit processor, built-in WiFi and Bluetooth, more RAM and Flash memory, more GPIO, more ADC, and many other peripherals :)
