We designed a OBD GPS tracker for a client in Australia. The requirements were very clear on what needs to be done and they wanted all the features present on the VALTRACK-V2. Basically, all my GPS trackers are the variants of the VALTRACK-V2 GPS tracker. Here are a few things i want to share about the design we did and the process we followed to get the prototypes working,
This post is about some of the design mistakes which I did in designing my GPS trackers and this mistake is associated with selection for the battery charger chips. I am sharing this so that you will be careful and aware when choosing the battery charger chips for your GSM based applications.
