Last fall, we wrote about Allwinner D1s/F133-A RISC-V processor and the upcoming MangoPi MQ1, a tiny 4x4cm board based on the processor. The board is not for sale, but we have more details, and the company is also working on an Arm version equipped with Allwinner T113-S3 dual-core Cortex-A7 processor that is pin-to-pin compatible with F133-A SoC.
The Allwinner F133-A board will finally be called MangoPi Nezha-MQ, or MangoPi MQ for shorts, and come with 64MB on-chip RAM while the Allwinner T113-S3 board, with 128MB on-chip RAM, will be named MangoPi MQ-Dual. Both are fitted with a Realtek RTL8189-based Wi-Fi module, offer display and camera interfaces, two USB-C interfaces, and headers for GPIOs.
MangoPi MQ/MQ-Dual specifications:
- SoC (one or the other)
- MicroSD card slot
- Footprint for SPI NAND/NOR flash
- Display I/F
- 15-pin FPC connector Raspberry Pi DSI display
- 40-pin FPC connector for RGB display with 4-wire resistive-touch interface
- 6-pin FPC connector for capacitive touch
- Camera I/F – 24-pin DVP interface (usable as RMII)
- Audio – On-board microphone, audio output via 2-pin header (unpopulated)
- 2.4 GHz WiFi 4 via Realtek RTL8189 module plus u.FL antenna connector
- 10/100Mbps Ethernet (RMII) via DVP camera interface (add-on board)
- USB – 2x USB Type-C ports with one USB OTG port and one USB host port
- Expansion – 2 x 22 pin expansion headers
- Misc – Boot/Fel & Reset buttons
- Power Supply – 5V via USB-C port
- Dimensions – 4×4 cm (four fixed assembly feet)
Both Arm & RISC-V boards support Allwinner Tina Linux operating system based on OpenWrt and Melis RTOS based on RT-Thread. One upcoming crowdfunding campaign on Crowd Supply for the RISC-V board also mentions RT-Smart developed by RT-Thread and described as a “high-performance microkernel operating system for professional, real-time applications.”. I’m not sure how it differs from RT-Tread IoT OS or Melis RTOS. Since memory is limited, the LVGL open-source graphics library will be used for demos using the displays. Hardware resources and demo firmware can be found on Github. There’s also a separate repository for MQ-Dual for it’s mostly empty for now with a photo and a description of the board.
