Hello.
I am having trouble uploading code to the ITEAD 3G shield. https://littlebirdelectronics.com.au/products/itead-3g-shield
I have attempted to upload the firmware (from here: https://www.itead.cc/wiki/ITEAD_3G_Shield), but it is never recognised by my computer. I have tried this on a Mac and a PC.
Any ideas?
