Lichee RV-86 RISC-V Linux 4-inch panel targets home automation, HMI applications

When Sipeed first introduced the Lichee RV module with Allwinner D1 RISC-V SoC last November, they also teased the Lichee RV-86, an “86 Box” with a 4-inch 480×480 touchscreen display, an XR829 WiFi and Bluetooth module, Ethernet (via USB), two microphones, a GPIO header, and support for WAFT (WebAssembly Framework for Things).

I’ve just noticed the Lichee RV-86 has been for sale for several months, so it may be interesting to have a closer look, and now there’s also an option to get a 720×720 touchscreen display.

Lichee RV-86 PanelLichee RV-86 specifications:

  • SoM – Sipeed Lichee RV Nezha compute module with Allwinner D1 RISC-V processor @ 1 GHz, 512MB or 1GB DDR3, microSD card slot, and USB Type-C OTG port
  • Display
    • 4-inch 480×480 IPS capacitive touch screen OR
    • 4-inch 720×720 IPS capacitive touch screen
    • It is also possible to connect an 8-inch 1280*800 IPS capacitive touch screen to the board
  • Audio – Onboard 1W mini speaker, dual digital microphone
  • Connectivity
    • 10/100M Ethernet via RTL8201F PHY and RJ45 plus power cable similar to the one found in IP cameras.
    • WiFi 4 and Bluetooth 4.2 via Allwinner XR829 wireless module + IPEX antenna
  • USB
    • USB Type-C OTG interface on the module
    • 1x USB Type-C host interface, 1x USB-UART Type-C interface
  • Expansion – 2x 16-pin headers with 2.54mm pitch for GPIOs
  • Misc- Power and Ethernet LEDs, reset button
  • Power Supply – 5V or 12V power supply (The diagram shows 5V+UART connector and 9 to 12V power connector)
  • Dimensions – 86×86 mm (optional 3D printed enclosure)

RISC-V 86 panel for home automation

The Lichee RV-86 panel supports Tina Linux (based on OpenWrt 14.4) and Debian, and Sipeed offers a docker development image with an “original SDK”. Documentation is a bit all over the place with the documentation website, OS and tools downloads on MEGA, and datasheets, 3D files, schematics, and other documents in a separate location on Sipeed website. The system would typically be used as a Smart Home control unit, but it can also be used for Alibaba’s WAFT (WebAssembly Framework For Things) evaluation.

I initially found the Lichee RV-86 for $64.90 on Seeed Studio (512MB RAM, 480×480 display, and enclosure), but you’ll get more options on Aliexpress with prices ranging from $55.00 to $98.80 depending on options. The cheapest module comes with 512MB RAM and a 480×480 display, but no 3D printed case, while the most expensive model includes 1GB RAM, a 720×720 display, a 3D printed enclosure, and a 32GB microSD card presumably preloaded with Tina Linux or Debian.

eth connector is in the cable (the cable usully used in IPC board, include power and eth lines)

Would have been nice if it supported PoE. Now it seems to be one connector for rj45 and one USB for power in the same cable.

I’d buy a few of these if they had POE!

It’s the same with doorbells, yet to see any reasonably priced doorbell with POE. It’s all WIFI which never works well with doorbells.

Maybe the next version!

Is the XR829 wifi chipset related to the horrendously buggy XR819 found in Orange Pi et al.? Just seeing the name gave me unpleasant flashbacks of trying to get it to work. I hope it’s not nearly as bad…
