The MEYD‑675 is a high‑performance, low‑power System‑on‑Chip (SoC) designed specifically for edge‑AI workloads in industrial, automotive, and consumer‑grade devices. By combining a heterogeneous compute fabric with an on‑die AI‑optimized memory subsystem, the MEYD‑675 delivers up to 2 TOPS/W (tera‑operations per second per watt) while maintaining a compact 12 mm × 12 mm footprint in a 7 nm FinFET process.

| Question | Answer | |----------|--------| | Can I add or remove sensors after purchase? | Yes. The MEYD‑675 uses a standardized M‑Connector (8‑pin). Swapping sensors is a tool‑free operation; the firmware automatically detects the new configuration on reboot. | | What is the warranty? | 3‑year limited warranty covering manufacturing defects. Optional extended warranty (up to 5 years) available. | | Is the data encrypted during transmission? | All LTE and LoRaWAN packets are encrypted with AES‑128 (LoRa) or TLS 1.3 (LTE). The on‑device storage can be encrypted with a user‑defined key. | | How do I update the firmware? | Over‑the‑air (OTA) via LTE or LoRaWAN (partial updates) or via USB‑C for full releases. The GUI shows the current version and any pending patches. | | Can the unit operate underwater? | The base model is IP67 (water‑resistant, not submersible). For underwater applications, the MEYD‑675‑U variant with a sealed pressure‑compensated housing (IP68) is available. | | Is there a developer kit? | Yes. The MEYD‑675‑DK includes a breakout board, API examples in Python/Node‑JS, and a simulated sensor suite for rapid prototyping. | | What is the typical latency for an alarm sent via LTE? | Under normal cellular conditions, latency is 150–300 ms from sensor trigger to cloud receipt. | | Question | Answer | |----------|--------| | Can
