MangoPi has opened $39 preorders for a 40 x 40mm “MangoPi-Nezha MQ” SBC that runs Linux or RT-Smart on a 1GHz, RISC-V based Allwinner F133-A SoC with 64MB DDR2. The SBC supplies 2x Type-C, WiFi, MIPI-DSI, RGB touch, DVP camera, GPIO, and audio I/O.
The MangoPi project from Beijing Wadora Technology Co. teased its MangoPi-MQ1 SBC last October with minimal details. The tiny RISC-V board has now arrived in a Crowd Supply campaign as the MangoPi-Nezha MQ. Equipped with the Allwinner F133-A (D1s), a spin-down of the Allwinner D1 that powers Sipeed’s LicheeRV SBC, the MangoPi-Nezha MQ is available for $39, with free global shipments starting on July 7. The SBC was originally intended to be sold for $10, but as we documented in our recent Linux hacker board catalog, prices are way up across the industry.
MangoPi is also prepping a MangoPi MQ-Dual SBC with the same form factor and features as the MangoPi-Nezha MQ, but with a dual-core Cortex-A7 Allwinner T113-S3. There are also preliminary product pages for an Allwinner D1-based MQ-Pro SBC, as well as MangoPi A1 (Amlogic S905) and A1-Pro (hexa-core -A73 and -A53 Amlogic A311D) SBCs (see farther below).

The open-spec, 40 x 40mm MangoPi-Nezha MQ runs the OpenWrt-based Tina-Linux, Debian, or the RT-Thread related RT-Smart microkernel OS on the single-core Allwinner F133-A. Like the Allwinner D1, the F133-A (D1s) has a 1GHz, Alibaba/T-Head XuanTie C906 RISC-V core, which integrates RISC-V RV64 vector extensions for AI applications.
The F133-A adds 64MB of DDR2 via a SIP module. Display output drops to 1080p60 from 4Kp30, and Allwinner has removed the HDMI interface and HiFi 4 audio DSP. The I2S/PCM and ADC interface counts have dropped from three to two.

The MangoPi-Nezha MQ is equipped with a microSD slot and a pair of USB Type-C ports, one of which powers the board. There is also a 2.4GHz WiFi chip, 44x GPIO pins, and media features that include MIPI-DSI, RGB with touch, and an amp, mic, and audio out header.
A DVP camera interface is said to support an add-on board with a camera and a 10/100 Ethernet port (via RMII). The Crowd Supply page has no details on the add-on, which will presumably be made available for order in the coming months.

Tina Linux, combined with the LVGL open-source graphics library, “allows you to take full advantage of the board’s hardware features,” says MangoPi. You also get RT-Smart, an open source microkernel OS for real-time applications that is developed by and related to RT-Thread. “Microkernels fill the gap between traditional real-time operating systems (RTOSs) and heavier solutions like Linux,” says MangoPi, which collaborated with RT-Thread and Allwinner on the MQ.
Specifications listed for the MangoPi-Nezha MQ include:
- Processor — Allwinner F133-A (1x XuanTie C906 RISC-V core @ 1GHz)
- Memory/storage:
- 64MB DDR2 (via SoC)

- Media I/O:
- MIPI-DSI (15-pin RPi compatible FPC)
- RGB (40-pin FPC with 4-wire resistive touch)
- Capacitive touch (6-pin FPC)
- DVP camera interface with RMII support for upcoming camera/LAN add-on
- 1W amp; capacitor microphone; audio out header
- Other I/O:
- 2x USB Type-C ports (1x host, 1x OTG)
- UART header
- 44-pin (2×22) GPIO with I2C, SPI, etc.
- Other features — Boot and reset buttons; LED; 4x fixed assembly feet
- Power — via USB Type-C OTG
- Operating system — Tina-Linux (OpenWrt-based); Debian; RT-Smart microkernel OS
MangoPi MQ-Dual, MQ-Pro, and A1/A1-Pro
MangoPi is prepping several new boards including a MangoPi MQ-Dual SBC. As reported by CNXSoft in mid-February, the Dual has the same PCB and features as the MangoPi-Nezha MQ, but with an Allwinner T113-S3 dual-core Cortex-A7 SoC with 128MB RAM.

MangoPi’s website also has a preliminary product page for an Allwinner D1-based, 65 x 30mm MangoPi-Nezha MQ-Pro, which is shown here. The SBC ships with up to 1GB DDR3 and offers microSD, 40-pin GPIO, WiFi/BT, mini-HDMI, 2x Type-C, DVP/RGMII, MIPI-DSI/LVDS, and audio out.

Finally, there is a MangoPi A1 and A1-Pro (no images) that run Ubuntu or Android 10 on either a quad-core Amlogic S905 or 3-TOPS NPU-equipped, hexa-core -A73 and -A53 Amlogic A311D (Pro). No RAM limit was listed, but preliminary specs include eMMC, microSD, HDMI 2.0, USB 3.0, USB 2.0, 2x Type-C, MIPI-DSI/CSI, 40-pin GPIO, WiFi/BT5, and an M.2 slot.
Further information
The MangoPi-Nezha MQ is available on Crowd Supply through April 14 at $39 with free global shipping. Shipments begin on July 7. More information may be found on the Crowd Supply page, the GitHub page, and the MangoPi website.
