1. Single-core ARMCortex-A732-bit core, integrating NEON and FPU 2. Built-in Rockchip's self-developed 4th generation NPU, with high computing accuracy, supports int4, in8, and int16 mixed quantization. The int8 computing power is 0.5TOPS, and the int4 computing power can reach 1. OTOPS supports C, C++, Micro-Python, for Arduino and other development environments 3. Supports multiple interfaces such as GPIO, UART, SPI, I2C, USB, etc. to facilitate development and debugging. 4. The design of the built-in RISC-V MCU supports low-power fast startup, supports 250ms fast snapshot, and loads the Al model library at the same time, enabling face recognition to be completed "within 1 second". 5. Integrated built-in POR, audio codec and MACPHY.
