Seeking advice on the feasibility of a project concept

as well as making the system a lot more complicated to maintain (I should note that I am only on a limited contract with the company, but they have several web and C# developers on site who make up the majority of the IT team - hence the main attraction to a JavaScript interpreter).

Good point... this is not just because of physical operation and software maintenance/lifecycle, but also for getting the hardware together and maintained... There are many simple ways to do things, for example add some power transistor to switch on and off any extra devices in the system beyond the main board, but it becomes challenging when having to get a replacement or a new node.

Because of the cost concern for using SD cards in the mix, I thought of just soldering an spi EEPROM/FRAM/MRAM to the board. Cost may be met that way, but maintenance would require more than what a Web (JS,C#) programmer profile includes.

This real-world use case sheds some light on what kind of shields would be useful... and I was thinking Espruion Pico shields!

To meet the requirements of this real-world use case a shield - or smart combination of shields - would have to provide:

• communication (long range, low power, periodic,...)
  
• power conversion/step-up - for RF and other things (many RF things just need more than 3V to get you somewhere - as other forum users experienced w/, for example, 315/433 MHz, cheap/simple devices. Alternatives: see LoRa(TM) - Ultimate Long Range Solutions).
  
• storage for fail safe (until communication is available again or time is ready to process received data
  
• power switch(es) beyond the current what a chip pin can deliver (could be combined with power conversion
  
  

@MetallixBrother, what type of Espruino board are you considering? A) Espruino standard (1.4)? - or B) Espruino Pico?
