Automotive environments have several particularities, which make it hard to design a power supply circuit.
Yes, there may be voltage spikes higher than 35V (even higher than 100V), negative voltage drops, etc.
I am looking for the best protected power supply regulator circuit for automotive...
This is meant for vehicles, so there are other factors to take into account, such as overvoltages, negative voltages, load dumps, etc. Capacitors alone are not enough to deal with them I believe.
Automotive Power Supply Regulator Circuit
Hi
I am working on a tracking system for vehicles (both cars and trucks).
The system power supply is the vehicle's battery (which supplies 12V or 24, for cars and trucks respectively), which may have many fluctuations (spikes, negative voltages, noise...
I have looked into ARM MCUs but because I have no clue about ARMs I was a bit confused by so much information.
Which is the best way to choose the right ARM MCU? Where can I get some information/guides for beginners in the ARM world?
Thanks for such great help.
Why would you say ARM is better? I was thinking about an AVR32 (I am more familiar with AVR8 ), what are the advantages of the ARM for my project?
The photos are the essential part of this project. I am aware of the restrictions of sending the photos in gprs.
What would be a generic solution for this project? Could something like this work: SIM548C + MCU (with at least 3 UARTs - GPS, GSM, camera) + Memory expansion + Linksprite's RS232...
I need GPS.
To sum up the system I am thinking is:
Camera for photos + GPS for coordinates + GPRS to send photo and coordinates.
What would you say is the best option? If I use GM862-GPS would I need an external MCU?
I was thinking about using Telit's GM682-GPS solution. However I am now considering Simcom's SIM548C. What are your thoughts about this module?
What would be the main differences between GM682-GPS and SIM548C?
SIM548C does not have an internal mcu, would it be very complex to use this module +...
Hi.
First of all, being my first post, I have to compliment the forum and its users for being such a helpful community.
I am designing a tracking solution with photos. I have done a project using the GM862-GPS before, a while ago.
My questions are:
- Is GM862-GPS still a good module? Or are...
