Raspberry Pi 5 redrew the SBC baseline, and NVIDIA Jetson Orin Nano Super dragged AI-edge performance into desktop-class pricing. PlatformIO has become the de facto standard for multi-target builds, and ESP-IDF v5.4 makes ESP32-P4 a first-class target. KiCad 8 threatens commercial PCB CAD, and M5Stack, Switch Science (Japan) and the Korean RP2040 community are maker-ecosystem hubs. This guide maps the entire 2026 embedded landscape — MCU/SBC/RTOS/build systems/debug/wireless/AI on MCU/OTA/PCB — with real chip names and measurable specifications.

STM32, ESP32-C6, RP2350 같은 듀얼-ISA 칩이 양산되고, Zephyr RTOS 4.0과 FreeRTOS 11이 표준 RTOS의 자리를 굳혔으며, Rust embedded(embedded-hal 1.0, embassy-rs)와 TinyGo가 진지한 옵션이 되었다. Raspberry Pi 5는 SBC의 기준점을 다시 그렸고, NVIDIA Jetson Orin Nano Super는 AI 엣지를 데스크톱 가격대로 끌어내렸다. PlatformIO는 다중 타겟 빌드의 사실상 표준이 되었고, ESP-IDF v5.4는 ESP32-P4를 본격 지원한다. KiCad 8은 상용 PCB CAD를 위협하고, M5Stack과 Switch Science(일본), 한국 RP2040 커뮤니티는 메이커 생태계의 허브가 되었다. 이 글은 MCU/SBC/RTOS/빌드 시스템/디버그/무선/AI on MCU/OTA/PCB까지 2026년 임베디드의 전체 지도를, 진짜 칩 이름과 실측 가능한 스펙으로 그린다.
