ATtiny13A/25/45/85 Development Programmer Board

ATtiny13A/25/45/85 Development Programmer Board is an indispensable tool for anyone working with the popular 8-pin ATtiny series of microcontrollers. This board removes the complexity of breadboarding and wiring, giving you a dedicated, reliable platform for prototyping and programming these compact chips. It features integrated sockets for both the DIP (through-hole) and SOP (surface-mount) versions of the ATtiny family, significantly speeding up your development cycle. Engineers and hobbyists rely on this programmer board to easily upload code, test basic circuits, and debug projects before integrating the final chip into a production environment. If you want to harness the power of the ATtiny chips efficiently, this board is the necessary bridge between your computer and your micro-project.

Key Features:

• Universal ATtiny Socket Support: Includes a ZIF (Zero Insertion Force) socket for DIP-8 chips and a dedicated footprint for SOP-8 chips, accommodating the ATtiny13A, 25, 45, and 85 series.
• Integrated ISP Interface: Features a standard 6-pin ISP (In-System Programming) header, allowing you to easily connect an external programmer like an Arduino UNO or USBASP.
• Onboard Testing Circuitry: Includes an integrated LED and a test button, enabling you to quickly verify that your code upload was successful and your basic I/O functions correctly.
• Compact and Portable Design: The small PCB size makes it convenient for use on a workbench or carrying in a toolkit for on-the-go development.
• Power Select Jumper: Offers a jumper option to power the target chip directly from the ISP programmer, simplifying your power setup during development.

Technical Specifications:

• Supported Microcontrollers: ATtiny13A, ATtiny25, ATtiny45, ATtiny85 (and other DIP-8/SOP-8 AVR chips with compatible pinouts)
• Programmer Interface: Standard 6-pin AVR ISP Header (MOSI, MISO, SCK, VCC, GND, RESET)
• Operating Voltage: Powered by the external programmer (typically 5V or 3.3V)
• Power Indicator: Onboard power LED
• Output Pins: All I/O pins of the ATtiny are broken out to header pins for easy prototyping.

Mechanical Specifications:

• Socket Type: DIP-8 ZIF Socket (lever type) and SOP-8 soldering pads.
• Connectors: 6-pin ISP header, 4-pin header for power, and numerous I/O breakout headers.
• Mounting: No dedicated mounting holes, designed for desktop use.

Dimensions:

• Length: ~35 mm
• Width: ~25 mm
• Height (with ZIF socket): ~18 mm

Pinout and Wiring:

• ISP Header: Connect the ISP header to your programmer (e.g., USBASP, Arduino as ISP) using a standard 6-pin cable.
• VCC/GND Jumpers: Set the power jumper to supply VCC to the ATtiny chip from the programmer’s power line.
• I/O Breakouts: Connect external components (LEDs, sensors, etc.) directly to the clearly labeled I/O pins (PB0, PB1, etc.) around the socket.
• Wiring Note: Ensure the orientation of the ATtiny chip matches the notch indicator on the ZIF socket to prevent damage during programming.

Commonly Used in:

• Microcontroller Development Labs: Streamlines the process of flashing firmware onto small-scale chips.
• Hobbyist Workshops: Provides a convenient, plug-and-play solution for learning and prototyping with ATtiny microcontrollers.
• Small-Scale Production: Used for burning the bootloader or final code onto chips before integration into finished products.

Applications:

• Code Upload: Easily upload Arduino sketches or pure AVR-C code to your ATtiny chip.
• Fuse Bit Configuration: Use the ISP connection to set crucial fuse bits for clock speed, reset functionality, and brown-out detection.
• Basic I/O Testing: Quickly test PWM, ADC, and digital I/O functions using the onboard LED and button.

Equivalent Models:

• Arduino as ISP Setup: A makeshift programmer using an Arduino board, less convenient but functional.
• USBASP Programmer: The programmer itself, often used in conjunction with this development board for a complete solution.
