Hello,
I was wondering how the board should be connected to the arduino. I've placed the boards on top of the Arduino UNO using the pins provided but I was wondering what specific pins are used (i.e pin 7, pin 6, etc)?
Would the Hologram SIM work in Canada? I was also thinking about using a Bell mobility sim SIM card.
Thank you!

In the LTE_Demo example sketch you should see the pins that are being used. Please see this wiki page for more details. Pins 10 and 11 are the most important (for UART communication with the module). Pin 6 is also needed to turn on the module. SCL and SDA are used for the I2C temperature sensor if you decide to use it. |

I am reading a BME280 Temperature/Barometric Pressure/Humidity I2C Sensor. Is there any way the SIM7000A can be corrupting the data? I am not reading temperature from the SIM7000. In fact, I bought both of my SIM7000A modules via Amazon and both are missing the chip. Does the SIM7000A use Mega 2560 pins 20 or 21 for anything?

No, the Botletics SIM7000 shield does not use pins 20 or 21 on the Mega. There may be an issue with the way you're reading the BME280. Are you using I2C or SPI? I would suggest using I2C because pins 10 and 11 are used for the SIM7000.

I2C.
Per your post above:
"In the LTE_Demo example sketch you should see the pins that are being used. Please see this wiki page for more details. Pins 10 and 11 are the most important (for UART communication with the module). Pin 6 is also needed to turn on the module.

SDA is on Mega pin 20 and SCL is on 21. But you say the SIM7000 doesn't use these?

Well, for your board version without the MCP9808 temperature sensor, it doesn't use SDA/SCL because there's no sensor to begin with. So if you attach the BME280 on SDA/SCL, it should work fine. Just make sure you have pullup resistors on the I2C lines. That is normally taken care of on the SIM7000 shield next to the MCP9808 sensor.
