AE-3588NBT: RK3588  Fanless Industrial AI Gateway | 6 TOPS NPU

Choose the AE-3588NBT for cost-sensitive indoor projects where a 6 TOPS onboard NPU is enough and the unit runs from -10°C to +60°C. Choose the AE-3588LBT when the model needs more AI headroom, because its M.2 slot adds an NPU module for up to 32 TOPS. Choose the AE-3588BT for energy, substation or outdoor sites that need RK3588J, 4000V isolated I/O and up to 58 TOPS. The RK3588 selection guide compares all three.

Not directly. The AE-3588NBT is an indoor gateway with an IP40 aluminum enclosure and a -10°C to +60°C operating range. For roadside cabinets, traffic monitoring or other outdoor sites, use a sealed, temperature-controlled cabinet or choose the AE-3588BT or an outdoor-rated BITECH platform.

No. The 2× RS-232 ports and 4-bit GPIO share a common ground with the system. That is fine inside one cabinet with a unified ground plane. For long cable runs, high EMI or devices on different grounds, add external isolators or move to the AE-3588BT, which adds 4000V isolated industrial I/O. See isolated vs non-isolated I/O for how to decide.

The 6 TOPS NPU supports INT4, INT8, INT16 and FP16 and suits lightweight detection, classification, OCR and people-counting models such as YOLO nano or small variants and MobileNet-class networks. Achievable frame rate depends on model size, input resolution and the number of streams, so benchmark your own model on a sample unit before fixing the camera count.

Export the model to ONNX or TFLite, then compile it to the .rknn format with Rockchip RKNN-Toolkit2. INT8 post-training quantization with a representative calibration set gives the best NPU throughput. Accuracy after quantization depends on the model and the calibration data, so validate it against your own production images before deployment.

Yes. It has one HDMI 2.0 input for 4K@60Hz capture and one HDMI 2.1 output up to 8K@60Hz, plus hardware decode up to 8K@60fps and encode up to 8K@30fps. A typical pipeline captures from a camera or vision source, runs inference on the NPU and renders the overlay on the output display. End-to-end latency depends on the capture source, model and rendering path, so measure it in your own setup.

The AE-3588NBT supports Android 12 with root access, Debian 11 and Ubuntu 20.04. BITECH provides the BSP with kernel source, toolchain and RKNN-Toolkit2, and can deliver a custom OS image with your drivers, application and boot configuration preloaded for series production.

It provides 2× Gigabit LAN, 2× RS-232, 4-bit GPIO, 2× USB 3.2 Gen1, 2× USB 2.0 and 4G/5G through Mini PCIe, with optional Wi-Fi 6 and Bluetooth 5.2. Power is 9–36V DC on a Phoenix terminal. For projects that need more fieldbus interfaces, compare the AE-3588LBT and AE-3588BT.

When input voltage drops below the 9V threshold, the power supervisor triggers a controlled shutdown so the system can flush caches and unmount the eMMC cleanly, reducing the risk of file-system corruption at unattended sites. A software watchdog and RTC with backup battery support automatic recovery. Confirm the power-loss protection option for your configuration when ordering.

BITECH offers 5–7 year supply for the AE-3588NBT with a controlled BOM and advance PCN notice before component changes, and every unit runs full-load burn-in before shipment. OEM options include OS images, I/O configuration and labeling, with MOQ and volume pricing on request. See lifecycle management and how we test every unit.
