Maix Bit Risc V

I recently came across an interesting AIoT device called Maix Risc V device. It was originally a crowd sourced campaign from Shenzhen, China. Being interested in exploring this architecture as well as neural  network processing, I decided to take the byte (Ha ha) and get one. Here is the package unopened.

Overview

 

 

Sipeed MAIX is the first RV64 AI board for Edge Computing, it makes AI embedded to any IoT device possible. MAIX have tons of excited features: Dual Core RV64 IMAFDC, 8 MB SRAM, Neural Network Processor(0.25~0.5 TOPS, support Tensor Flow Lite), APU, hardcore FFT... All this is in Square Inch, 0.3 W! Also we have made it breadboard friendly with micro python available. MAIX is open mind, everyone can contribute code/document, trade network module. MAIX can Maximize AI's power.

 

 

Sipeed MAIX: AI at the edge

 

 

AI is pervasive today, from consumer to enterprise applications.

With the explosive growth of connected devices, combined with a demand for privacy/confidentiality, low latency and bandwidth constraints, AI models trained in the cloud increasingly need to be run at the edge.

MAIX is Sipeed’s purpose-built module designed to run AI at the edge, we called it AIoT. Add to that a KPU(Neural Network Processor) inside.  This 64 KPU which is 576 bit width, supports convolution kernels and any form of activation function.

 

Without any more ado, here are the parts for the kit opened up:

I hope to expand more as I uncover and learn about this board. Drop a comment or two to let me know what do you think and maybe what uses you can come up with.

    These development boards come in several different variations. I've decided to try the "Maixduino" which is quite a bit larger because of the Arduino form factor but it includes an ESP32 for WiFI and Bluetooth…

    I've seen those from Seeed but haven't got around to trying one. I'll be interested in seeing how you do with it. Did you get a new version or old version? The new version has the MEMS microphone.

    Over the weekend, I continued to used my Maix Bit and was successful using the video to the LCD. It was very clear and had nice colours to boot. When I get time, I intend to do a separate write up...

    Seems like a prototype is done and looks like a Raspberry Pi Hat:

    Wow! Artificial Intelligence.image So anyone be interested in this if they have a Raspberry Pi?

    These development boards come in several different variations.  I've decided to try the "Maixduino" which is quite a bit larger because of the Arduino form factor but it includes an ESP32 for WiFI and Bluetooth and also has a speaker port.  I think the other specs are similar but I haven't checked out how the IO is pinned out.  Seems inexpensive enough to give it a try.  I'll be interested to see what tool flow you use for programming.

    I finally assembled the pieces and it looks like:
