In 2025, the embedded industry remains vibrant. STM32, RTOS, IoT, Edge AI, automotive electronics… which direction is the most worthwhile to learn?
This article outlines the 5 most promising directions in embedded development, combining job roles, salaries, and skill requirements for a comprehensive understanding!
💡 Why should you care about the “direction”?
Embedded technology spans a wide range, with significant differences between competition-level and enterprise-level products.Do you want to work on projects? Earn a high salary? Join a big company? Or start your own business? Choosing the right direction can save you 2 years of detours!
Direction 1: STM32 + FreeRTOS (Mainstream for Mid-Range Control)
STM32 remains the “king of entry points” for embedded engineers, especially suitable for the following groups:
-
Newcomers / Students
-
Those looking to transition from C language projects to hardware control
-
Projects in industrial, instrumentation, small appliances, or student competitions
✅ Application Areas:
-
Industrial equipment, instrumentation, power control, electronic competitions
-
Smart locks, wristbands, sensor terminals
✅ Recommended Tech Stack:
STM32CubeIDE, HAL Library, FreeRTOS, UART/I2C/SPI, ADC, DMA
✅ Salary Reference:
Entry-level 6k~9k, 1-2 years of experience can reach 10k+
📌 It is recommended to pair with OLED/DHT11 projects and practical RTOS multitasking scheduling to enhance resume highlights.
Direction 2: IoT Development (Cloud-Edge-End Collaboration)
If you are familiar with STM32, transitioning to IoT is a very smooth advancement direction.
✅ Application Scenarios:
-
Smart home, building monitoring, agricultural weather stations
-
NB-IoT, Wi-Fi, LoRa, BLE devices
✅ Recommended Tech Stack:
ESP32 / STM32 + MQTT + Alibaba Cloud IoT Platform / RT-Thread / Mini Program Interaction
✅ Salary Reference:
8k~15k; those skilled in cloud configuration and OTA updates earn higher salaries.
📌 Project Suggestions: Remote temperature and humidity collection, web-controlled lighting, remote OTA firmware upgrades, etc.
Direction 3: Embedded Linux (Advancing to High-Level Systems)
Compared to bare-metal systems, Linux driver development/system trimming is more favored by large companies.
✅ Application Directions:
-
Industrial control gateways, edge computing boxes, smart gateways, video surveillance devices
-
In-vehicle IVI systems, ARM platform development boards (e.g., RK3568)
✅ Recommended Tech Stack:
Yocto / Buildroot, uboot, kernel, device tree, driver development, SPI/I2C/MIPI debugging
✅ Salary Reference:
10k~20k; large companies like Hikvision, BYD, and aerospace companies offer better compensation.
📌 It is recommended to work on Linux porting projects or camera drivers, as they hold high value.
Direction 4: Edge AI + Embedded Vision (Combining AI with Industry)
AI does not only belong in the cloud; Edge AI is a rapidly emerging new field in recent years.
✅ Application Directions:
-
Industrial visual inspection, warehouse sorting, smart cameras, voice recognition terminals
-
AIOT (Artificial Intelligence + IoT)
✅ Recommended Tech Stack:
ARM + OpenCV + TensorRT + yolov5/yolov8 + ncnn + MaixPy (K210)
✅ Salary Reference:
12k~25k; those familiar with algorithms and hardware deployment are considered “scarce talents”.
📌 Project Suggestions: Local target recognition vehicles, K210 face recognition access control, etc.
Direction 5: Automotive Electronics / New Energy Embedded (Continuously Rising Popularity)
New energy + autonomous driving + automotive control is booming, leading to a large demand for embedded positions.
✅ Application Directions:
-
BMS battery management systems, ECU controllers, T-BOX, instrument control
-
High-level autonomous driving domain control (MCU responsible for low-level control)
✅ Recommended Tech Stack:
AutoSAR, CAN/LIN, functional safety (ISO26262), MCU communication, automotive-grade software architecture
✅ Salary Reference:
14k~30k+; large automotive companies like BYD, Huawei’s automotive BU, Xiaopeng, and Li Auto have high demand.
📌 It is recommended to start with STM32 development for CAN communication to accumulate project experience and gradually transition to automotive systems.
✅ Summary: The 5 Most Promising Directions in Embedded Development for 2025
Final Thoughts
STM32 is not outdated; rather, your understanding of it may still be limited to lighting up an LED.
