The reason why there are fewer Grove connectors in the latest version is that we are trying to avoid confusion caused by the reuse of GPIOs.
SeeeduinoXIAO has led out 14 GPIOs including 3.3V/5V and GND. Other 11 GPIOs will be used as:
The add-on SD card would be able to expand memory for Python and the library, just as the same function of SPI-flash and larger memory space.
SAMD21 MCU already include an RTC but Seeeduino XIAO did not lead out the required pin for it, so it may be more practical to just add another RTC chip on board.
For the more number of Grove IIC you are expected, we didn’t put two of it only because of the space concern, and Grove IIC Hub would be able to fix the problem if more IIC devices are needed, so we keep only one on board.
Glad to hear that. My suggestion is that you could have a look at our newest released products to see what new projects you could build. No need to force yourself to apply anything you do not really need or you already have. Our review will be flexible to some extend, so just illustrate what you are going to build, components you are going to use, indicate what you already have so you do not need to apply for it. If your project is selected, we may also offer a coupon for your future purchase. Looking forward to your project:)
Don’t worry, we will take all users’ inputs into serious consideration. And that’s why we put the design here to ask for more opinions.
Though I spend some time on the design of new style silk print, so far it seems classical type is more popular in the forum.
Glad to know that you like the OLED.
I found that too many Grove is not friendly enough as it will cause confusions for users when many GPIOs being reused. For this reason, I have to some extend abandoned the previous design that have eight Groves.
According to your last reply, I modify the design as folow. May also have a look:
SPI Flash is replaced by SD card since it will have the same function, and SD card could be removed and it is more convenient to copy things somewhere else using card reader.
I did not draw RTC chip on board but will find the appropriate space to allocate it.
I’m very Glad to see you take the time to ASK.
as an aside, You DO NOT always include the pins for the Xiao’s etc.
Why not switch to a Socket on the Board.or here When a person orders a chip and dev board and when they recieve it. ONE must solder to even get up and going. I see this as a barrier to entry for many new people wanting to try your Xiao chips. Imagine the " 3rd Grader’s " the ability to open the product and place it in and program it WOW and Your on the Path of learning WAY faster than anything from Adafruit, DF-robot, Hak5 ?, Sparkfun is the closest IMO.
Lastly IS it really the " Premier " well it would be if it checked all the boxes.
Hope that Helps
Happy Holidays & Merry Christmas
