GL.iNet Slate OpenWrt Travel Router Supports Tor, Wireguard VPN, and Cloudflare DNS over HTTPS/TLS

A couple of months ago, we wrote about GL.iNet Mudi portable WiFi router with built-in 4G LTE connectivity and supporting features such as the Tor Project, up to 25 VPN providers, and Cloudflare DNS over HTTPS or TLS.

Mudi was launched on Kickstarter and should start shipping very soon, but I was informed about another OpenWrt travel router from the company with GL.iNet Slate also supporting many of the same features, but doing away with built-in cellular connectivity and battery.

GL.iNet Slate

GL.iNet Slate (GL-AR750S-Ext) router specifications:

  • SoC – Qualcomm QCA9563 MIPS 74Kc processor @ 775MHz
  • System Memory – 128MB DDR2
  • Storage – Dual Flash 16MB NOR + 128MB NAND, MicroSD card slot up to 128GB
  • Networking
    • Ethernet
      • 1x Gigabit Ethernet WAN
      • 2x Gigabit Ethernet LAN
    • WiFi
      • Dual-band 802.11 b/g/n/ac WiFi 5 with transmission rates up to 300Mbps (2.4GHz) + 433Mbps (5GHz)
      • 2x 2dBi external antennas
    • 3G/4G – Optional via cellular USB dongle
  • USB – 1x USB2.0 port, 1x Micro USB port for power only
  • Misc – Reset button, mode switch
  • I/O Expansion – Internal headers with I2C, UART, GPIO, 3.3V & 5V
  • Power Supply – 5V/2A
  • Power Consumption – < 6 Watts

  • Weight – 86 grams

GL-AR750S Specifications

The USB port can be used to connect external storage (formatted with FAT32, NTFS, EXT4, EXT3, or EXT2), and 3G/4G LTE USB dongle. The router can be connected to the Internet over an Ethernet cable, in repeater mode, via a cellular dongle, or using tethering to your smartphone over the USB port. Secure communication can be configured with OpenVPN, Wireguard VPN clients/servers, or the Tor Network, and Cloudflare DNS over HTTPS or TLS can be optionally enabled in the user interface as well. You’ll find everything to get started on GL.iNet Docs website.

Slate Board

We can see 7-pin on the board for I2C, UART, and GPIOs, but those are not controlled from the user interface, and you may have to drive those from the command line or your own daemon.  GL.iNet provides source code for U-boot,  but I can’t see anything specific for OpenWrt from the company themself, and instead, you’ll find firmware and instructions on OpenWrt website. There’s also an alternative community firmware called ROOter GoldenOrb.

GL.iNet Slate travel router can be purchased for $69.99 on Amazon.

    1. Indeed! I have been in discussion with the manufacturers about respinning the board with the USB ports rearranged somewhat, as only one of the two ports on the SoC can be used in OTG mode, and that port is currently connected to a USB hub that also provides the uSD card reader functionality.
      Rewiring the board with the Host-only SoC port connected to the external USB port, and internal USB header via the USB hub/uSD chip, and leaving the OTG-capable port connected directly to the micro-USB port would be a perfectly viable option, as far as I can see.

    1. Yes, there is very granular control of routing between the wi-fi and LAN and WAN ports. You get direct access to the routing tables from the GUI and I assume from the command line as well – not that I am well-versed enough to do all of that. I am very impressed with the company’s devices and am using one now, connected to proton VPN via the built-in openVPN client. The SMB file-sharing is useful. I did have to install vsftpd manually – very surprised that it had SMB but not FTP by default – but is was no harder than on any linux device via CLI. That took less than 5 minutes to configure and is working great. Love this device.

  1. RPi has more memory and CPU power if you need to route a lot more, say 500 Mbps worth of pirate movies via bittorrent.

    1. Jerry, will you ever stop promoting piracy ? You’re doing a big disservice to the community you claim to represent (RPi).

  2. @cnxsoft: With regards to sources, GLInet have a fairly active Github account, with OpenWrt and uBoot mirrors, amongst other things:


    Also, if you are looking for Qualcomm datasheets, there is a handy github repo at with a LOT of datasheets collected from various locations. A useful resource, which even has a (slightly) more recent QCA9563 datasheet than the one you linked above.
