The data acquisition module is mounted in their cars and sends updates on transactions, location and many other parameters to a MQTT server via the cellular network. The result is an IoT solution to easily monitor all cars in their fleet.
The scope of this iteration was to develop the existing software to work with new sensors and to add data logging to the existing setup.
Later on, the hardware required an update as well to accomodate some new I/O's and a new user interface to simplify the operation for the user.
More information can be found on the Frolic Studio website.
For this project I used the following techniques:
-PCB design (Eagle)
-Digital circuit design
Shell Tapup circuit boards before the update
