Orange Pi has published hardware details for the OrangePi O1, a 90 × 70mm SBC based on the Sophgo BM1688 processor. It pairs eight Arm Cortex-A53 cores with a RISC-V C906 coprocessor and a 16-TOPS INT8 TPU, along with up to 16GB of LPDDR4/LPDDR4X memory.

The BM1688 integrates eight Arm Cortex-A53 cores operating at up to 1.65GHz on the OrangePi O1, alongside a RISC-V C906 coprocessor running at up to 1.2GHz. According to Sophgo, the integrated TPU provides peak performance of 32 TOPS at INT4 and 16 TOPS at INT8, as well as 4.0 TFLOPS at FP16/BF16 and 0.5 TFLOPS at FP32.

The processor targets edge AI applications including large language models, vision-language models, image analysis and multi-object tracking. Sophgo lists support for Caffe, PyTorch, TensorFlow, ONNX and MXNet.

The OrangePi O1 is listed with 8GB or 16GB of LPDDR4/LPDDR4X memory. Storage options include optional 16GB, 32GB, 64GB or 128GB eMMC modules, optional 128Mb or 256Mb SPI flash, a microSD card slot supporting cards up to 128GB, an M.2 M-Key interface for PCIe 3.0 NVMe SSDs and a SATA 3.0 interface. Orange Pi notes that the eMMC and SPI flash options are mutually exclusive.

The BM1688 also includes hardware for video and image processing. Orange Pi specifies H.264 and H.265 decoding of up to 16 simultaneous 1080p30 streams and encoding of up to ten 1080p30 streams, along with JPEG encoding and decoding at up to 480 1080p frames per second.
