I require a hardware designer/Company to develop a vehicle locator and controller module design for prototype
It must accept an input voltage of 6-30volts - Reverse polarity protection and transient supression for noisy vehicle environment required. An internal fuse must be of the ressetable type.(like bournes PTC).
Rechargable battery backup that will last at least 1 month when external power removed.
PCB mounted GSM and GPS antenna's.
sim card holder must be lockable not push in - push out
red network status led (seperate gpio is provided)
All gpio must be protected like the primary power supply
Unit must pass electronic test and independent inspection.
On completion all designs will be handed over to me.
