Radxa ZERO 2 Pro is a ultra tiny high performance SBC[1] using the
Amlogic A311D chip that ships in a number of eMMC configurations:
- Amlogic A311D SoC
- Quad A73 + Dual A53 CPU
- Mali G52-MP4 GPU
- NPU (5 TOPs)
- 4GB LPDDR4 RAM
- 32/64/128GB eMMC
- micro SD Card slot
- Wi-Fi 5 and BT 5.0
- 1x USB 2.0 Type-C port (OTG)
- 1x USB 3.0 Type-C port (Host)
- Micro HDMI 2.0
- MIPI DSI
- MIPI CSI
- 40 Pin GPIO header
