The basic board for AVR ATmega32 and ATmega16 boards. The board is hassle free of soldering and has 32 I/O pins with standard ISP download interface. There is easy replaceable crystal oscillator with expandable. It has features like  Power indicator , Programming working indicator , power reset button and for extra channels of external power (VCC and GND).

 The Auto programmer USB to TTL has dual voltage support with the MSP430 BSL burn mode. It work with STC12 series, STC11 series, STC15 Series Burning. The STC Microcontroller Upload Process is very convenient with this device. It has 500 MA resettable fuse in-built with aluminum housing that protects burner motherboard. It supports Windows OS and has status indicator flashes included. The interface definition are printed on the shell. The program automatically download without cold start and there is no frequent power-off power required to the microcontroller.

The AT tiny development board support chip of ATtiny45/ATtiny85 ATtiny13A/ATtiny25 and many more .It is convenient and fast programming with pluggable development board.

 STM 8 Development Board is a very useful Development Board Module that uses STM8S103F3P6 as microcontroller. This Module is very suitable for learners for learning STM 8S microcontroller. It has various features like: - Directly plugged onto the MB102 breadboard, On-board SWIM interface, Programmed with ST-LINK V2, On-board reset button & power indicator LED, On-board test indicator LED & the beginners can program to control it, On-board 200ma 3.3V Regulator and many more. It can be suitable for various applications like: - Power supply, Analog-to-digital converter (ADC), Clock management, Reset control and development, Debugging tool support, STM8 software tool chain and many more.

The ST-LINK/V2 is an in-circuit debugging and programming for the microcontroller families STM8 and STM32 . The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used.  To communicate with any STM8 or STM32 microcontroller located on an application board the SWIM (single wire interface module)  and SWD (JTAG/serial wire debugging interfaces) are used. It has a direct firmware update feature supported as well as status LED which blinks during communication with the PC. It has USB 2.0 full speed compatible interface. 

The USBASP AVR Programmer is a USB 2.0 version in-circuit programmer for various Atmel's series like: - ATMEGA, ATTINY, AT90, AT90CAN and AT90PWM microcontrollers. It can be applicable in various electrical and DIY projects.

A Propeller is used in Quad copter /Drone that helps transmits power by converting rotational motion into thrust. It doesn’t bend in normal air flow speed. The size of this propeller is 10 *4.5 inch. They have light weight, to help improve the air-powered efficiency and aerofoil stability

A Propeller is used in Quad copter /Drone that helps transmits power by converting rotational motion into thrust. It doesn’t bend in normal air flow speed. The size of this propeller is 8*4.5 inch.

 The TECI-12706 Thermocouple Module is a semiconductor based electronic component that works as a small heat pump. This thermocouple create a temperature differential on each side i.e. one side gets hot and other side gets cool.  To avoid burn of the module it must be used in conjunction with a heat sink. The module has 127 couples in-built. It is mostly used in computer CPU, portable refrigerators, Temperature stabilizer, Liquid cooling, Photonic and medical systems and many more. It is also knows as Thermoelectric cooling module, Peltier modules, Thermoelectric modules.

The Raspberry Pi 3 has BCM2837 system-on-chip.  It is a credit card sized computer including ARM11 processor. It is designed to provide a platform for experimentation and education in computer programming. It can be used as a normal desktop PC. The boards have one to four USB ports with a standard 3.5 mm phono jack for audio output. It can be used in education, home automation, industrial automation and many more

 The ESP-01S Relay Module is based on AI-Thinker ESP-01S Wi-Fi Module. It is mostly used in smart home to control any device with the help of phone. The demo code is already uploaded in the ESP-01S just required to supply a DC5V and you can control it. It is designed for DIY projects, internet of things and smart home. It can be used by its APP or LUA source code can be used.
