Overview
The SparkFun COM-24309 is an AVR ATtiny microcontroller IC housed in a 14-PDIP package. It features an 8-bit architecture with a maximum clock speed of 20MHz. The device includes 8KB (4K x 16) of FLASH memory for program storage. This component serves as a development board based on the ATtiny series, designed for integration into electronic projects requiring compact processing capabilities.
Feature Summary
- Integrates an 8-bit AVR ATtiny microcontroller core
- Operates at a maximum frequency of 20MHz
- Provides 8KB of non-volatile FLASH memory
- Utilizes a 14-pin dual in-line package
Applications
- General-purpose embedded control systems
- IoT prototype development
- Educational microcontroller training
- Compact sensor node processing
Procurement Notes
Verify that the specific part number corresponds to the SparkFun breakout board containing the ATtiny MCU rather than the standalone discrete component. Confirm the package type matches the required 14-PDIP form factor for your PCB layout. Ensure compatibility with the intended voltage levels and programming interfaces supported by the onboard circuitry before finalizing procurement.
Selection Notes
Select this module when a pre-assembled development environment for the 8-bit AVR ATtiny architecture is required. It is suitable for projects needing 20MHz processing power and 8KB of flash storage within a standard DIP footprint. Consider the availability of Qwiic or other interface support if system expansion is planned beyond basic digital I/O operations.
Part Context
This item represents a SparkFun Electronics product utilizing the STMicroelectronics AVR ATtiny microcontroller family. SparkFun engineers these boards to facilitate rapid prototyping and learning. The COM-24309 specifically targets developers seeking accessible hardware for implementing logic control and data processing tasks in small-scale electronic designs.
Replacement Considerations
Direct substitutes include other SparkFun ATtiny breakout boards such as those based on the ATtiny85 or ATtiny1614, depending on pin count and memory requirements. Alternative generic development boards supporting the same AVR architecture may be used if physical footprint constraints are flexible.
