- Supports up to 32 GB LPDDR4 memory and up to 256 GB eMMC storage
The SDRAM is 32bits data width, 4 ranks LPDDR4 memory capacities from 4GBytes to 32GBytes.
The system flash memory supports eMMC 5.1 memory capacities from 32GBytes to 256GBytes.
The default memory setting is 4/16GBytes LPDDR4 and 32/128GBytes eMMC for Blade 3.
1.5.2 MicroSD Socket
The MicroSD socket accepts standard 11mm x 15mm Micro-SD cards with capacities up to 256GBytes. The 4bits data interface supports the SDMMC3.0 protocol. While the default boot setting is the eMMC Flash which can change to the MicroSD card.
1.5.3 Mini-PCIe Socket
The mini-PCIe is a PCI card interface with a small form factor that uses a standard 52-pin mini-PCIe socket. It also contains a USB 2.0 interface.
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 3588. Since each module needs specific configuration definitions, check the configuration setting before connecting the module.
USB Support
The mini-PCIe socket supports a standard USB 2.0 interface.
1.5.4 Gigabit Ethernet
The IEEE802.3 compliant Ethernet supports auto-negotiation of 10/100/1000/2500Mb half-duplex and full-duplex. The RGMII interface from the processor connects the 2.5GbE to an external PHY, RTL8125BG-CG. The RJ45 connector has some status and speed lights. The green light indicates that you are connected, and the flashing light indicates that data is being sent. The yellow light indicates 2500Mbps and is turned off for 10/100/1000Mbps.
1.5.5 Power Input
Power Delivery (PD)
The power port is a USB-C port that supports USB Power Delivery 2.0. A Power Delivery controller on board allows for a maximum power input of 20V @ 3A.
12V DC
DC power inputs from a DC SATA power via U.2 port require 12V @ 3A.
1.5.6 USB 2.0/3.0 Host Ports
The Blade 3 features two USB Type-C ports. Both ports can support the USB-OTG capability as well as DisplayPort via USB Type-C. DisplayPort over USB Type-C enables the USB Type-C connector and cable to offer audio/video (AV) transfer via the DisplayPort interface.
It supports DisplayPort 1.4 and has a maximum resolution of 7680×4320@30Hz.
USB Type-C Port-1 supports USB PD2.0 but not USB 2.0 for ADB.
Although USB Type-C Port-0 does not support USB PD2.0, it does support USB 2.0 for ADB debugging and firmware updates.
1.5.7 Display Support
The video output processor supports the resolution from 1920×1080@60Hz to 7680×4320@60Hz.

1.5.9 LEDs and Dip Switch
The power LED indicates the status of the power supply. There is one SPST four-position dip switch that can be used to determine the system booting mode of the Blade 3 board. Only one position can be turned ON at a time; please keep in mind that you cannot switch two positions to ON at the same time.
When position 1 is set to ON, the Blade 3 will boot from eMMC.
When position 2 is set to ON, the Blade 3 will boot from the MicroSD card.
When position 3 is turned ON, the Blade 3 will boot from SPI Flash.
When position 4 is activated, Blade 3 enters MaskROM mode for firmware development.
