It seems the MKR GSM 1400 has the same uBLOX GSM processor on it - how hard do you think it would be to run these under the Particle ecosystem, as a compound?
@joearkay, the board uses a Cortex M0+ class processor with only 256KB of flash and 32KB of RAM. The Electron, on the other hand, or more specifically the E0 module (which uses the SARA-U201), uses a Cortex-M3 class processor (STM32F205RCT6) with 1MB flash and 128KB RAM. Using the MKR GSM 1400 would be like going back to the old Spark Core days! So the quick answer would be “difficult” and “highly unlikely”.
