Thanks for replying Brian!
We tried switching regulator using LM2576 which works ok but not to our full satisfaction. Also, it uses more components resulting in a higher cost and space thus making the product costlier/bigger than ideal. Chinese clones using ELM327 are able to use linear regulators for doing the same job (sending OBD commands, getting replies and passing them via Bluetooth) so wondering if it is possible to do the same here using STN-1110. So far we are struggling to explain what is going on and why the board is heating up.
Appreciate any advice on what are the key points to note and any limitations that we should be aware of. Is it the hardware (i.e. circuit) or software (i.e. sleep, etc) that we should focus on.
