Breadboard header for ATTiny

This handy breadboard header for ATTiny 25/45/85 microcontroller is a new design based on the original idea from Tinkerlog. Maybe the most useful feature is that it can provide power to the vertical breadboard strips while connecting all six port pins to the horizontal strips. Other features are: 6-pin ISP connector (works great with USBtinyISP programmer), easily accessible reset button, header for optional ceramic resonator, power LED indicator, smoothing caps. Measuring approx. 4 x 2.5 cm (1½ x 1 in) is a great addition to your breadboard projects saving lots of extra connections. More: R1 10k? R2 330?

Don't forget to solder the wire link under the IC socket (red line)!

The described breadboard header serves as an efficient interface for the ATTiny 25/45/85 microcontroller, facilitating easy integration into prototyping environments. The board's design allows for power distribution to vertical breadboard strips, ensuring that the microcontroller and peripheral components receive the necessary voltage and current.

Key components include a 6-pin In-System Programming (ISP) connector, which is compatible with the USBtinyISP programmer, allowing for straightforward programming and debugging of the microcontroller. The reset button is conveniently placed for quick access, enabling users to reset the microcontroller without needing to manipulate the breadboard setup.

The board features a header for an optional ceramic resonator, which can be used to stabilize the microcontroller's clock signal, improving timing accuracy in applications. A green LED indicator is included to provide visual feedback on power status, enhancing usability during development.

Capacitance is managed by two capacitors: a 100nF capacitor (C1) for decoupling and a 100uF/16V capacitor (C2) for smoothing out voltage fluctuations, which is crucial for maintaining stable operation of the microcontroller and connected devices.

The board is designed to accommodate various header configurations, including 1x2, 1x3, 1x6, and 2x3 arrangements, enhancing flexibility for connecting additional components or modules. An 8-pin IC socket is provided for the ATTiny microcontroller, allowing for easy replacement and ensuring that the microcontroller can be securely mounted.

It is essential to solder the wire link beneath the IC socket as indicated (red line) to ensure proper connectivity and functionality of the board. This design consideration is crucial for maintaining the integrity of the circuit and ensuring reliable operation during prototyping and testing.This handy breadboard header for ATTiny 25/45/85 microcontroller is a new design based on the original idea from Tinkerlog.
