I’m doing a fleet monitoring project with the Fez spider kit + seeed gps & seeed gsm modules.
The problem is that the gsm module restarts the whole system when it doesn’t get enough power.
Specs on the sim900 module shows that it needs 2A during some peeks, and that it will restart if the current drops below 3,1V.
We have done everything we can through software (fixed different problems in the seeed drivers), but the problem seem to persist. Sometimes it helps changing the power module, the cables and mainboard.
Does anyone have a suggestion for a more permanent solution?
Maybe something like capacitors on an extender or something?
