At Mouser.com the data sheet (https://www.mouser.com/datasheet/2/872/gpy-specsheet-1129416.pdf) shows the two IPX connectors as for WiFi/BLE and LoRa/Sigfox with NO connector for LTE. In the PIN OUT the LoRa/Sigfox connector becomes the LTE connector... At your site the gpy board is shown with LTE and WiFi on the top then a bottom shot with another IPX connector doing nothing. https://docs.pycom.io/chapter/gettingstarted/connection/gpy.html
On the Pycom Products page you show GPy (You change the case of your product name randomly !) as having WiFi, Bluetooth and LTE. This means the Product Data Sheet at Mouser is wrong.
Trying to make a purchase decision but your lack of attention to important details worries me.
Thank you for the heads up, unfortunately it seems an older pre-release version of the datasheet slipped into Mouser.
We'll contact them to update it.
