Building a weather station on a wisblock that will need to use NB IoT to send its data out.
Will need a I2C interface (temp/humidity), an ADC (wind direction) and at least 2 GPIOs (wind speed interrupt and rain gauge interrupt). Previously using LoRa this worked well with the IO expansion board.
If I plug the NB IoT board on it uses the same slot as the IO expansion - are there enough required pins (listed above) on the Base Board or core I am using (Lora)?
Can IO2 (pin 3 on J11) be used as a GPIO?
Or is there an NB IoT core available?
thanks
