- Users must implement **external protection** (e.g., fuses, TVS diodes) for sensitive components.

- **ESD (electrostatic discharge) protection** is minimal, requiring careful handling during assembly.

8. **Software Limitations**

- **No built-in RTOS or advanced scheduling** users must implement timing logic manually for real-time applications.

- **Memory constraints** on some modules (e.g., older Arduino-based ones) may limit the complexity of firmware.

- **No native support for some protocols** (e.g., CAN bus requires additional adapters), adding complexity for certain applications.

9. **Cost Can Add Up for Large Projects**

- While individual modules are affordable, **bulk purchases for complex systems** (e.g., 10 modules) can become expensive.

- **Shipping costs** for international orders (common for EasyIO-J2) may increase the total price.

- **Custom modifications** (e.g., adding extra I/O) may require purchasing additional components, increasing costs.

10. **Compatibility Issues with Some Platforms**

- While it works well with **Arduino and Raspberry Pi**, integration with **lesser-known microcontrollers** (e.g., some STM32 boards) may require **custom drivers**.

- **ESP32/ESP8266 users** must ensure proper **UART/SPI pin assignments**, as some modules may conflict with Wi-Fi/BLE functionality.

- **Linux-based systems** (e.g., Raspberry Pi OS) may require additional **kernel modules or drivers** for certain interfaces.
