Awesome!

Would be nice to have some basic sensors on the board. Something most commonly used for Machine learning.
You already have camera. Nice.

Ideas to add:
* Motion sensors (3 axis accelerometer at minimum, additional 3 axis gyro would be good. 3 axis magnetometer is a nice plus)
* One microphone
* Connector for Sipeed 6+1 Microphone Array

Make it a real edge device by including LoRaWAN.
It seems there isn't enough space for LoRaWAN....a LoRaWAN HAT could be more handy.

A microphone could be useful.
Thanks for the suggestion, will add a microphone in the next version~~

Awesome stuff! I suggest to put at least a couple more Grove connector sockets on the board, there seems to be enough room left. This would allow to connect several additional Grove sensors (there are many for about anything), which could be used as additional input to ML models and allow to do sensor fusion projects (because using AI for camera only is somewhat limiting). Grove actuators can be hooked up as well to sockets (relays, motor controller, etc.. there are a lot of Grove accessories) and can for example be controlled from the output of a ML model; this is easy to do. I suggest to put the additional Grove sockets vertically, just like on the Seeeduino Lotus board instead of lining them up at the edge of the PCB. You could probably have 4 analog and 4 digital ports, instead of 2.
Thanks for the suggestion. From the current layout, there isn't much space for extra 4 grove ports....We need also try to make the look of the board more harmonious, maybe we can make those horizontal ports become vertical too, thus can make more room for extra Groves, will try~~

I reckon that this would make a pretty awesome platform for introducing students to RISC-V, JTAG, and debugging.
Several ideas;

Raspberry Pi as a JTAG tool - please layout the Grove AI HAT PCB to connect the JTAG pins of the SiPEED MAIX-1 to suitable GPIO pins on the HAT connector so that the Raspberry Pi can be used as a JTAG tool. eg https://github.com/synthetos/PiOCD/wiki ... TAG-Dongle

SPI comms with the Raspberry Pi - please layout the Grove AI HAT PCB so that a Raspberry Pi SPI master on the HAT connector (Raspberry Pi is only an SPI master) can talk to an SPI slave on the SiPEED MAIX-1 (SPI much faster than UART...). However, unlike the K210, the Raspberry Pi doesn't have a full FPIOA, so you will have to accommodate its limited choice of HAT pin functions when you layout the Grove AI HAT PCB - only some HAT pins can be used for SPI etc.


Power sharing - please tie the +5Vdc plane on the Grove AI Hat PCB to the +5Vdc pins on the Raspberry Pi HAT connector. Depending on current draw, this will allow both the Raspberry Pi and the HAT to be powered from a single power supply connection (one cable instead of two!)
Really appreciate your idea, in fact, we have already connected the power on the AI HAT on the Raspberry Pi HAT connector, in order to protect the circuit, we also add a switch to change the power mode.

For SPI connector and JTAG, we will evaluate and try to add them in the final version. Will get you updated~Thank you!

An RTC can be useful.

Is there any USER defined button?

This looks amazing with a lot of possibilities! If we are using it with Raspberry Pi, we do not need wifi, bluetooth, sd card module but of course as a standalone unit we might need it. I was working on the "Recognition of Activities of Daily Lives (ADL)" and there was requirement for a 3-axis accelerometer. The problem is: if we use 3-axis accelerometer grove module, for better result it should be mounted parallel to the board. It would be very helpful to add a 3-axis accelerometer on the board itself which I think would not take much space. It will be beneficial for other use cases like auto-rotate lcd screen, free fall detection (to save data before it crashes!), almost all robotics projects (auto driving) needs it. I am eager to try it out soon!
Thanks for the suggestion, a 3-axis accelerometer sensor integrated on the board is surely more convenient than using Grove. Will try to find a cost-effective one so that not adding too much cost for our users, do you have any recommendation for the 3-Axis accelerometer sensor?

Thanks for the suggestion. Seems microphone and motions sensors are very demanded. Will possibly adding a 3-axis accelerometer instead of 9-DOF because 9-DOF will cost a lot more. For 3-Axis gyro and 3-Axis magnetometer, a Grove module can be handy.

RTC requires space....we can also use Grove - RTChttps://www.seeedstudio.com/Grove-RTC-p-758.html, or Pi RTC HAThttps://www.seeedstudio.com/Pi-RTC-DS1307-p-3213.html.
