Firefly Core-1808-JD4

Firefly Core-1808-JD4

With on-board RK1808 AI chip which inbuilt high-efficiency NPU, it possesses a strong calculation capacity and supports multiple AI framework and AI application SDK, being easy to develop. With rich interfaces for AI applications, it is convenient for extension and can be applied to voice wake-up, speech recognition, face recognition and other application scenarios.

Key Features

  • The CPU of RK1808 AI chip adopts the dual-core Cortex-A35 framework with the maximum frequency of 1.6 GHz. Its VPU supports the encoding and decoding of 1080P regular video format as well as the camera video signal input with the inbuilt ISP.
  • With high-speed device interfaces like 1×USB2.0 and 1×USB3.0 (TX and RX used along with PCIE), and a series of input and output interfaces like PWM, I2C, SPI and UART. It supports MIPI/CIF/BT1120 video input, MIPI/RGB display output, Gigabit Ethernet and external WiFi/BT modules.
  • The inbuilt NPU has a calculation capacity up to 3.0 TOPs, supports INT8/INT16/FP16 mixed operation, and coordinates performance, power consumption and operational precision to the greatest extent. It also supports the network model conversion of frameworks like TensorFlow, Caffe, ONNX and Darknet.
  • Equipped source code, tutorial, technical materials, and development tools are provided, making development easier and more convenient.
  • It has wide applications in voice wake-up, speech recognition, face detection, attributive analysis, face recognition, posture analysis, target detection and recognition, image processing, etc.
