Just a follow up. I contacted M5Stack tech support and they told me the old modules have pins that are 2.5mm and the new board has pins that are 3mm. So in theory I have the newer board but it separates from the Core2 fairly easily. Meaning the pins are probably making contact but not great. Will have to get longer screws and screw the module down to ensure good contact. For reference to separate from the Grey Core it is very tight and I usually use a screwdriver. I measured and the Grey Core lets the pins seat approximately 1mm more than the Core2. Here is a picture showing how to measure pin length.

RE: Check SD Card Status
Ok, I have figured out how to detect when the card is ejected by writing a file within a try - except but once the card is out I have not figured out how to get it re-mounted in code. I can get it re-mounted by resetting the CORE2. The scenario would be you eject the card and the CORE2 detects it and notifies the user to insert a new card. Once the card is inserted the CORE2 would automatically mount it and make it available for use. I am sure there is a simple command that I am missing.
Thanks for any help.try:
with open('/sd/IsCard.txt', 'w+') as fs:
fs.write('Test Write')
with open('/sd/IsCard.txt', 'r') as fs:
label1.set_text(str(fs.read(10)))
label0.set_text('Card has been read')
NoCard = 0
except:
label0.set_text('Except0')
NoCard = 1
label0.set_text('Card Not Installed1') -
RE: Core 2 and GPS Pins Still To Short
By your website I meant the m5stack.com website. In the previous post it was indicated that the new stock would have longer pins. So, I was just checking to see if maybe I ordered right during the transition and if I order another it will have the longer pins.

Core 2 and GPS Pins Still To Short
This is a follow up on the post from a month ago regarding compatibility with the GPS module and the Core 2.
On Dec 24th I ordered the u-blox NEO-M8N $26.39 module from your website. It works fine with the Grey Core. I recently received the Core2 and the pins are too short to connect. So, has something changed since I got this module? In addition what back will need to be utilized and how does the battery connect to the mother board with the GPS module in between the battery and the motherboard? I assume that the M5GO Battery Bottom2 feeds power through the interface connector to the motherboard to overcome this problem? Is this correct?

Check SD Card Status
I know how to read and write the SD Card but I am unsure how to check the status. I have tried using Try and Except but still have not go where I wanted. The goal is to tell if an SD card is inserted and formatted if not prompt the user to insert a proper card. Since I am presently working in Blockly and inserting Python code using the Execute block a solution that met this requirement would be great. Thanks

Core2 Port I2C Not Working
I have a grey core and have used the TOF sensor with success, utilizing UI-FLOW. I just got a Core2 and burned UI-Flow into it. When I attach the TOF sensor to port A it appears to not be able to be read on the I2C bus. Any suggestions?
Thanks
