Can we use Wio Terminal as a Raspberry Pi hat by connecting the 40 pins header? Will RPI power it from the headers? Where can I find pin mapping of ATSAMD51P19 to 40-pins headers?
Another question, there is an FPC connector on the Wio Terminal, what is it for? I could not find any documentation.
Wio Terminal is currently available on normal Serial communication with RPI(USB), and we are working on Wio Terminal as USB-C Screen for RPI. you can find pin map on our wiki : https://wiki.seeedstudio.com/Wio-Terminal-Getting-Started/#pinout-diagram
FPC headers were not used yet, more to released very soon 
Thanks @ansonhe97 for the info! How can I access Digital/Analog/I2C/SPI pins in an arduino sketch? What are their names and corresponding locations on the headers? It is not clear in the link you shared in the previous message for pinout diagram.
Hi please follow through our wiki: https://wiki.seeedstudio.com/Wio-Terminal-IO-Overview/
You can see from the left panel, there are more infos:
Any updates on Wio terminal as an RPi USB C display?
We finished developing, the source code is here: https://github.com/Seeed-Studio/Seeed_Arduino_USBDISP
We will document a wiki very soon
That’s a good news! I have been eagerly waiting for this long since. I tried the NonFunctional sketch but I guess it is doing nothing. Do we need to connect to the RPi USB 3.0 port? Do we need to run something at RPi, too? I need it to try out for an almost finished project soon so any quick working example will be helpful.
The current version also needs to install a Linux driver with RPI. In the future, we will achieve full platform-independent use.I hope you like the hardware and software.
Great! BTW what is the refresh rate?
It hasn’t been tested, but from the naked eye, the minimum is 30FPS
Hi@yokonav ,we have released a demo for Wio Terminal to enumerate a USB Display Device and simulate mouse by buttons. You can look about it from: https://github.com/Seeed-Studio/Seeed_Arduino_USBDISP/tree/master/examples/USBDisplayAndMouseControl
