The Avrisp MKII Programmer Schematic: A Low-Cost Solution for AVR Microcontrollers

When it comes to programming AVR microcontrollers, one of the most popular options is the Avrisp MKII programmer. Designed with ease of use and affordability in mind, this programmer has become a staple in many electronics projects. In this article, we'll take a closer look at the Avrisp MKII programmer schematic and explore its features and capabilities.

One of the standout features of the Avrisp MKII programmer is its ability to power the target microcontroller from the programmer itself. This means that you can program your AVR microcontroller without needing an external power source, which can be especially useful in situations where space is limited or power availability is a concern. The programmer is capable of delivering up to 500mA of power, making it suitable for a wide range of applications.

Another key benefit of the Avrisp MKII programmer is its buffering and power protection capabilities. This means that you can use the programmer with a high degree of confidence, even if you're planning to perform some more aggressive programming operations. The programmer's robust design ensures that it won't be damaged by accidental overvoltage or other forms of abuse.

In terms of compatibility, the Avrisp MKII programmer is designed to work with a wide range of AVR microcontrollers, including the popular ATmega168 and ATmega328. It also supports AVRDude, which is a widely-used programming software for AVR microcontrollers. This makes it easy to get started with the programmer, even if you're new to AVR development.

One important note about compatibility is that the Avrisp MKII programmer may not work with all AVR microcontrollers. Specifically, the ATmega2560 used in the Arduino Mega is not compatible with this programmer. However, the ATmega328 used in the Arduino Uno and RedBoard works perfectly, making it a great option for those looking to program these popular boards.

The Avrisp MKII programmer is also a collaboration between SparkFun Electronics and Limor Fried, which is a testament to its quality and reliability. The programmer's design is based on Dick Streefland's USBtiny and Limor Fried's USBtinyISP, which ensures that it has a solid foundation in terms of performance and functionality.

In conclusion, the Avrisp MKII programmer schematic is a low-cost solution for AVR microcontrollers that offers a range of benefits and features. Its ability to power the target microcontroller, buffering and power protection capabilities, and compatibility with AVRDude make it an excellent option for those looking to program their AVR microcontrollers quickly and easily. With its affordable price point and robust design, the Avrisp MKII programmer is a great choice for anyone looking to get started with AVR development.
