Toybrick TB-RK1808M0 Mini-PCIe Compute Card (hereinafter referred to as compute card) configured with Rockchip RK1808 neural network processor, 1G DDR4 memory and 8G EMMC. With a standard Mini-PCIe interface, compute card support USB3.0 and mini-PCIe transfer mode by DIP switch, if equipped with RK accessory, the following two modes can be realized:
Add-in card installed in a mobile platform.
Logical Representation of the PCI Express Mini Card.
Compute card also support some custom IO, include GPIO, Uart, USB3.0 OTG, USB2.0 Host, Reset and recovery. With these custom IO, compute card can not only be used as mainboard to control the peripheral hardware, but also be integrated into the artificial intelligence motherboard as a compute module to receive the control signals which come from the host. This greatly expand the IO capacity of the Mini-PCIe compute card and improve the IO performance.
As an artificial intelligence compute card, Mini-PCIe compute card has the characteristics of high performance, low power consumption and standard interface. It can be widely used in various fields of artificial intelligence. With the powerful artificial intelligence computing ability, Mini-PCIe compute card can build the artificial intelligence algorithm on the edge of the network and be easy to upgrade the traditional embedded devices and extend these devices artificial intelligence capability.
