If you are looking for a cost-effective edge processor for embedded and IoT applications, the Rockchip RK3566 is a solid option worth checking out.
RK3566 is a quad-core Cortex‑A55 SoC with built‑in NPU for lightweight AI inference, 4K video decoding, and rich peripheral interfaces. It is widely used in industrial boards, handheld devices, smart gateways, and vision edge boxes. Compared with higher-cost chips like RK3568 or Raspberry Pi 4, it balances power consumption, performance,e and BOM cost well for mass production.
Key highlights of RK3566:
- Quad-core ARM Cortex-A55 up to 2.0GHz
- Built-in NPU supporting INT8 AI inference
- Mali-G52 GPU supports 4K H.264/H.265 decode
- Wide IO support: GPIO, UART, I2C, SPI, Ethernet
- Mainstream Linux SDK support, easy custom firmware development
