    15: Robot on the Front

    Andreas Eieland, who runs flash microcontroller product lines at Atmel, explains the origins of the AVR processor, its Harvard architecture, and why it became the foundation of the Arduino ecosystem. He details how Atmel’s strategy of providing cheap, easy-to-use silicon and supporting open-source communities like AVR Freaks drove organic adoption by makers and students. The conversation covers the technical trade-offs between 8-bit AVR and 32-bit ARM Cortex-M0+ architectures, focusing on power consumption, cost, and the transition from prototyping to production. Eieland also highlights Atmel’s recent SAM D20 Xplained Pro development kit and the company’s expansion into Wi-Fi connectivity to support IoT applications.
