$4 Orange Pi 4/4B PCIe Expansion Board Includes an mPCIe socket, and a SIM card Slot

Orange-Pi 4 PCIe Expansion Board

Rockchip RK3399 based Orange Pi 4 & 4B boards launched last year with a PCIe connector. But the PCIe interface is available via a 24-pin FPC connector, not quite a standard like a PCIe slot or mPCIe socket, and hard to use for most projects as you’d need to make your own PCIe adapter board. But it’s now become much easier to use the PCIe interface as Shenzhen Xunlong Software has now launched a $3.90 expansion board connecting to the 24-pin FPC connector, and allowing users to connect mPCIe cards, especially the ones for 3G/4G connectivity as a SIM card slot is also included.PCIe expansion board specifications: 24-pin FPC PCIe connector to Orange Pi 4/4B with PCIe, USB, power “key”, and GPIO1_A0 (See schematics below) mPCIe card socket SIM card socket Misc – Reset key Dimensions – 58 x 32 mm The company confirmed the PCIe interface should work in both Android and Linux. It might be good if they …

Gen 3 Intel Movidius “Keem Bay” VPU Introduced at 2019 Intel AI Summit

Intel Movidius Keem Bay VPU

Intel made announcements about upcoming AI solutions at 2019 Intel AI Summit. Those include Intel Nervana Neural Network Processors (NNP) for training (NNP-T1000) and inference (NNP-I1000) for cloud and data center customers, as well as Gen 3 Intel Movidis “Keem Bay” VPU. We’ll focus on the latter in this post with Intel claiming similar performance as NVIDIA Jetson AGX Xavier at much lower power consumption with claims of up to 4.7 times more power efficiency when using ResNet-50 benchmark inference measurement using INT8 with a batch size of 1. Considering Jetson Xavier AGX has a ~30W power budget, that would mean Movidius “Keem Bay” consumes around 6 Watts.  Compared to Myriad X MA2085, the new Gen3 VPU is said to have more than 10 times the inference performance. Intel did not provide any TOPS figure, but considering the company announced 1 TOPS of neural compute performance for Myriad X, one may expect Keem Bay to deliver 10 TOPS. The higher …
