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.

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.

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 2×2 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.

WiFi-BT Module Architecture

MicroSD Socket

The MicroSD socket accepts standard 11mm x 15mm Micro-SD cards with capacities up to 64 GBytes. The 4bits data interface supports the SDMMC3.0 protocol. The default boot setting is the eMMC Flash which can change to the MicroSD card.

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.

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.

Gigabit Ethernet

The IEEE802.3 compliant ethernet supports 10/100/1000Mb half-duplex and full-duplex auto- negotiation. The GbE communicates to an external PHY, RTL8211F-CG, through an RGMII interface from the processor. The RJ45 connector contains status and speed lights. The green light is on for connected and flashing for data transmitting. The yellow light is on for 1000Mbps and off for 10/100Mbps.

Power Input

Power Delivery (PD)

The power port uses a USB-C port, which supports USB PD 3.0 . An on-board Power Delivery controller allows the maximum power input of 20V @ 3A. The Edge 2, as device mode, can be communicated by USB-C, which supports USB 2.0 for ADB debugging, firmware update.

12V DC

DC power inputs from a DC power jack socket or a SATA power socket require 12V @ 3A.

USB 2.0/3.0 Host Ports

Edge 2 has three standard USB 2.0/3.0 host ports using type-A connectors and one USB 2.0/3.0 port connects M.2 socket. These USB 2.0/3.0 ports are provided by a USB 3.0 hub, VL817. The three type-A connectors support 5V at 1A power and dependent software power dis/enabling.


RS485 connector has three pins, pin A, B, and GND for communication. RS485 connects to UART4 in CPU via interface IC, SP485REN-L. RS485 is a half-duplex bus with a default setting on receiving state. It will automatically switch to the sending state when needed. RS485 uses full isolation designs, the power supply and ground are isolated from the module used in the board, and the signal is isolated by an optocoupler.

Display Support

The video output processor supports the resolution from 1920×1080@60Hz to 4096×2304@60Hz and three simultaneous displays in the following interfaces. The default main display is HDMI.


HDMI display compliant HDMI 1.4 and HDMI 2.0. It supports up to 1920×1080@120Hz and 4096×2304@60Hz resolution.


The eDP display supports up to 2560×1600@60Hz resolution, up to 4 lanes of 2.7Gbps/lane. The 30-pin FPC connector includes the eDP interface and a backlight source. The pin assignments are listed in the next chapter.


The MIPI-DSI display supports two channel DSI and 2.5Gbps maximum data rate per lane. It supports up to 1920×1080@60Hz display output for single-MIPI mode and 2560×1440@60Hz for dual-MIPI mode. Two MIPI-DIS interfaces use 30-pin FPC connectors, MIPI-DSI0 and MIPI-DSI1, which include one channel MIPI-DSI and one touch panel signal (TP). The connectivity is shown in the following figure:

MIPI-DSI Architecture

U.2 Connector

The U.2 interface uses a 68-pin U.2 connector including a standard SATA signal, which supports 5V at 3A maximum, a SATA 3.0/PCIe 2.0 signal, a USB 2.0 signal, and another set of RGMII for ethernet.

Buttons & LEDs

The POWER button controls three statuses of the device, on, off, and sleep. Short press POWER button to turn on device when the device is off, press and hold POWER button to turn off device. Short press POWER button to enter sleep mode when the device is on. Short press RESET button to reset the device. When the device is on, press the RECOVERY button and hold, it will restart and restore the factory settings.

The MASKROM button is for development only, hold the MASKROM button and power up (or reset). The system will enter MaskROM mode for firmware development.

The power and system LEDs indicate the statuses of the power supply and system operating. And two small LEDs on the front side of board indicate the network status of M.2 and mini-PCIe modules.
