FII-PRA040 RiscV Educational Platform is a ready-to-use development platform designed around the Field Programmable Gate Array (FPGA) from Intel Altera. RISC-V (pronounced “risk-five”) is an open-source hardware instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles.

The RISC- V Foundation is a non-profit entity serving members and the industry and was originally developed in the Computer Science Division of the EECS Department at the University of California, Berkeley.

Recently RISC-V and GigaDevice announced the GD32V Series, which is said to be the world’s first 32-bit general-purpose microcontroller based on the RISC-V core.

Today we released Longan Nano development board powered by GD32VF103CBT6 MCU today and it only costs $4.90.

Sipeed Longan Nano is a development board based on GD32VF103CBT6 MCU with RISC-V 32-bit core of GigaDevice.
It is convenient for students, engineers and geek enthusiasts to contact the new-generation RISC-V processor.
Longan Nano comes with a 0.96inch 160×80 IPS RGB LCD and an acrylic transparent case.

Besides Longan Nano, let’s through back to take a look at what happened about RISC -V at Seeed Studio in 2019. Please don’t forget our full selection of Sipeed products, which will help you a lot to getting started with AI projects in a cost-effective way.

February – $7.9 RISC-V Module – Sipeed MAIX-I module w/o WiFi ( 1st RISC-V 64 AI Module, K210 inside)

MAIX is Sipeed’s purpose-built module designed to run AI at the edge, we called it AIoT. It delivers high performance in a small physical and power footprint, enabling the deployment of high-accuracy AI at the edge, and the competitive price make it possible embed to any IoT devices. As you see, Sipeed MAIX is quite like Google edge TPU, but it act as master controller, not an accelerator like edge TPU, so it is more low cost and low power than AP+edge TPU solution.

RISC-V is the new hotness, and companies are churning out code and announcements. Eventually, RISC-V microcontrollers and SoCs will cost just a few bucks. This day might be here, with Seeed’s Sipeed MAix modules. it’s a RISC-V chip you can buy right now, the bare module costs eight US dollars, there are several modules, and it has “AI.”

 

March – Grove AI HAT for Edge Computing

Next, in March, we released Grove AI HAT.

The Grove AI HAT for Edge Computing is built around Sipeed MAix M1 AI MODULE with Kendryte K210 processor inside. It’s a low cost but powerful raspberry pi AI hat which assists raspberry pi run the AI at the edge, it also can work independently for edge computing applications.

The MAix M1 is a powerful RISC-V 600MHz AI module that features dual-core 64-bit CPU, 230GMULps 16-bit KPU(Neural Network Processor), FPU(Float Point Unit) supports DP&SP, and APU(Audio Processor) supports 8 mics. In addition to the powerful Kendryte K210 processor, the Grove AI HAT for Edge Computing board provides a wealth of peripherals: I2C/UART/SPI/I2S/PWM/GPIO. The HAT also offers an LCD and a camera interface, which supports the Sipeed 2.4inch QVGA LCD and DVP camera, it will be helpful and convenience with your AI vision project.
