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.
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!
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
It seems there isn’t enough space for LoRaWAN…a LoRaWAN HAT could be more handy.
Thanks for the suggestion, will add a microphone in the next version~~
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~~
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?
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.
I think ST LIS2DH12 is low-cost and ultra-low-power and also useful for gesture recognition, free fall and wake up detection and many other features.
For Raspbeery Pi + the AI HAT, the lithum battery would run out very rapidly :mrgreen:
UPDATE: We just got the first look of this Grove AI HAT for Edge Computing and Raspberry Pi based on the Sipeed MAIX-I, including LCD and Camera Interfaces, connectors for Digital, I2C, UART and Analog.
Don’t hesitate to share your thoughts and ideas with us in this forum! Let us know what features you would like to see and have the chance of making it to the final product.
Wow, looking cool! Hoping to see an accelerometer in the next revision and want to try it out soon.
I think it’s a good idea to add a connector for a battery pack, not to power the board with the battery only but to have an UPS for short power failure. It could be very useful to prevent data corruption.
Is there a release schedule for the revisions posted (for easy lookup) and order placement?
Thanks for all the wonderful ideas! Here is an update about things we are going to add to the next version.
- There AI HAT can power Raspberry Pi directly. Just use the onboard switch to switch power mode.
- There will be a microphone on board, the same microphone as the Sipeed 6+1 micarray.
- There will be an ADXL345, 3-Axis Accelerometer on board. We choose this one because there is already a Grove version of the sensor, the software is ready, easier to get a sample, and also lower cost.
- There will be a user button, and the boot LED can be used as user LED.
- The 40-Pin interface will be changed to SMT female header.
- The JTAG package will be smaller.
We will finish the layout in a week, and get samples of the second version in the week of 22-Apr. If everything goes well, we will do pre-order in early May.
Welcome to more ideas about how to using Grove with this HAT~
