AVR 40-Pin Project/Development Board
The AVR 40-Pin Project / Development Board is a reliable platform for ATmega16/32-based development, learning, and embedded system prototyping.
🧾 Product Description
The AVR 40-Pin Project / Development Board is a versatile and easy-to-use platform designed for developing and testing 40-pin AVR microcontrollers such as ATmega16, ATmega32, ATmega8535, and compatible ICs. It provides a stable hardware environment for learning, prototyping, and embedded system development.
The board includes essential onboard components such as a crystal oscillator, reset circuitry, power supply section, and ICSP header for in-system programming. All microcontroller I/O pins are clearly labeled and brought out to headers, making it simple to interface with LEDs, switches, LCDs, sensors, relays, and other external modules.
Ideal for students, educators, hobbyists, and professionals, this development board is widely used in AVR programming training, academic projects, automation systems, and industrial control experiments. It supports programming via popular tools like USBasp, AVR ISP, and other compatible programmers.
