1.5 Key Component Specifications
The key component specifications are described below with relevant hardware information and
developing notices. For more information, pin assignments and signal descriptions are listed in
Chapter 2, Connectors & Pin Assignments.
1.5.1 MIXTILE Core 3568
The Core 3568 is a System-on-Module that expands all CPU functions to pins with an innovative
connector. The Rockchip RK3568 ARM64 CPU contains many peripherals to support multi-purpose.
Quad Cortex-A55 processing cores
Core operating frequencies up to 2.0GHz
Neural Process Unit with processing performance up to 0.8 TOPS
Support 4k@60fps H.265/H.264/VP9 decoder; 1080P@100fps H.265/H.264 encoder
LPDDR4 SDRAM supports up to 8GB
The SDRAM is 32bits data width, 4 ranks LPDDR4 memory capacities from 2GBytes to 8GBytes. The
system flash memory supports eMMC 5.1 memory capacities from 16GBytes to 256GBytes. The
default memory setting is 2/4GBytes LPDDR4 and 16/32GBytes eMMC for Edge 2.
1.5.2 Wi-Fi 6 / Bluetooth
Edge 2 integrates a Wi-Fi and Bluetooth module AP6275S, that can wake up the device from sleep
mode. AP6275S supports Wi-Fi 6 and dual-mode Bluetooth 5.0 that could interact with different
vendors’ 802.11a/b/g/n/ac/ax 2x2 Access Points with MIMO standard and can accomplish up to a
speed of 1200Mbps with the dual stream. Wi-Fi wake and enable signals connect to GPIO0 in the
processor, which can be operating while the device is sleep.

1.5.3 MicroSD Socket
The MicroSD socket accepts standard 11mm x 15mm Micro-SD cards with capacities up to 64GBytes.
The 4bits data interface supports the SDMMC3.0 protocol. The default boot setting is the eMMC
Flash which can change to the MicroSD card.
1.5.4 M.2 Socket
M.2, Next Generation Form Factor (NGFF), is specified for expansion modules. The M.2 interface
uses a standard 75 pins B key socket, which supports USB3.0-based WWAN modules, PCIe-based
WWAN modules, and PCIe-based SSD modules. The M.2 socket supports the module sizes of 2242,
3042, and 3052.
The module supporting configuration, including power, reset, and interrupt signals, is under
software control by Core 3568. Since each module needs specific configuration definitions, check
the configuration setting before connecting the module.
SIM Support
The M.2 socket includes a SIM socket with the SIM_M.2 mark, which supports 12mm x 15mm
micro-SIM cards for 4G/5G cellular function. This socket does not support dual SIM.
USB Support
The M.2 socket supports one standard USB 3.0 interface. Since the USB 3.0 data signals and one
lane of PCIe data signals are using the same set of pins, a GPIO is used to select USB 3.0 and a
lane of two-lane PCIe 3.0 signal.
PCIe Support
The M.2 socket supports a two-lane PCIe 3.0 interface. Edge 2 uses PI6C557-03BLE as a clock
generator to provide a 100MHz clock signal for the CPU and M.2 socket. For full functioning of
the two-lane PCIe signal, the selecting GPIO, PCIE_USB_SEL_GPIO1_D0 , needs to set LOW to
active.
1.5.5 Mini-PCIe Socket
The mini-PCIe is a small form factor PCI card interface, which uses a standard 52 pins mini-PCIe
socket. It contains a USB 2.0 interface with a supported SIM signal. The mini-PCIe socket supports
the module sizes of 3052.
The module supporting configuration, including power, reset, and interrupt signals, is under
software control by Core 3568. Since each module needs specific configuration definitions, check
the configuration setting before connecting the module.
SIM Support
The mini-PCIe socket includes a SIM socket with SIM_Mini mark, which supports 12mm x 15mm
micro-SIM cards for 4G cellular function. This socket does not support dual SIM.
USB Support
The mini-PCIe socket supports a standard USB 2.0 interface.
