RISC-V is a trending now, we have seen more and more RV32 chips last few years, but the RV64 chip which able to run standard Linux System is rare and expensive.

Now, we have an affordable choice for 64bit RISC-V SBC: Nezha.

Nezha is based on Allwinner’s newest RISC-V chip, D1 @1.0GHz(T-Head XuanTie C906 core), with 1GByte DDR3 and 256MByte onboard Nand Flash. 
It has basic resources and environments that allow you to research RV64 features on itself, just like a desktop PC.
It is likely your first universal RV64 Linux SBC~

Nezha is not designed for heavy computation applications but designed for the RV64 opensource community and IoT application.
It is easily run without a heatsink, and the temperature is below 50℃, chip power consume < 0.1A@5V
Nezha has most of the peripherals you need in IoT applications:  MIPI LCD, HDMI, USB, ETH, SPI/UART/IIC/PWM/LEDC/IIS/GPIOs.
You can build your projects easily and quickly.

Nezha has an open-source SDK thus that will allow us to port Debian Desktop System to it, and we can test many popular program environments on it: C/C++, JS, WASM, Rust, GoLang, Python, etc.

Nezha is the first Sub-100$ RV64 Linux SBC that can run almost all regular software development experiments, the Basic Kit(With cables and pre-burned Debian image micro SD card) starts from $99.

This campaign is authorized by Allwinner Online, aim to promote RV ecology .

We will send out the first 100 boards before the campaign end(20days). Both Telegram Group and Forum are open for communication.

Allwinner D1 is a special chip for opensource community, so the SDK is offical opensource!

you can refer to this post from cnx-software to get orignal SDK: 

https://www.cnx-software.com/2021/05/02/allwinn…

It is in process now,

Please join our Telegram group: https://t.me/joinchat/551j3yJa09owZTA1

• Tina: modify of OpenWRT, offical SDK support
• Debian 11: baisc desktop enviroment ported by Sipeed & RVBoards (separately)
• Fedora, Gentoo, Ubuntu: in process

• 2021.4: Verify the HardWare of Nezha, porting Debian and other drivers
• 2021.5.20:   lanuch crowdfunding
• 2021.5.30:  send out first batch boards (basic package about 100pcs)
• 2021.6: send out second batch boards (about 100pcs)
• 2021.7: send out third batch boards (reset)

Due to this year’s chip shortage and market strategy, the first C906 RV64 board’s price is much higher than we estimated last year (https://www.cnx-software.com/2020/11/09/xuantie…), but it is also a critical step for RV64 Linux SoC popularization.

AFAIK, we will meet next step (Sub-10$ RV64 Linux SBC) half years later.

Nezha (哪吒) is a protection deity in Chinese folk religion. His official Taoist name is “Marshal of the Central Altar” (中壇元帥). He was then given the title “Third Lotus Prince” (蓮花三太子) after he became a deity.
