Recently my companies focus has shifted over to cellular, as such we’re considering designing a custom PCB based on the STM32F205 series micro and U270/280 blox module (as used on the Electron). We’d like to leverage the great work Particle has put into this ecosystem and as such would like to run the Particle electron firmware, and use the cloud etc.
I’ve been watching the discussion over here which as some excellent information regarding compliance. However a lot of the information pertains to using the actual electron module and leveraging existing modular approval etc. This is still a possibility for us but probably not ideal due to size constraints and future mass production issues.
I’m interested to know if many other companies are going down this path, if so can they help with some of these questions?
I assume Particle has put in substantial time gaining approval from Telcos for the use of the Blox module on their networks? Will this approval need to be redone, or can we just drop in a SIM and assume it’s all good because we’re using the same hardware.
It seems that unless using the same Taoglas antenna that at least some intentional radiator testing will be required even for the Electron. If unable to leverage the Electrons modular approval, does anyone have experience regarding the testing requirements for a custom PCB?
Probably more questions but I’ll leave it at that for now, any help would be much appreciated!
