Completed the PCB

Completed the routing of the PCB. Used the thick traces for the high current lines.
i have placed the 5v regulator ic in such a way that it can be screwed to the same heat sink as the Amplifier ic

Started Work on the PCB

i had a few 3.5mm ports lying around which were salvaged from a old radio so i wanted to make use of those but i couldnt find a footprint for it so had to make it myself from scratch
took some time but finally after taking many printout to check the hole to hole compatibility and finally made it

Read the Datasheets and Completed the Schematic

So went throught Datasheet for the TDA7269A ic and looked at existing examples out there and started out with the Schematic.

Ive added 3 kinds of input

• 3.5mm jack
• BT module
• 3 wire JST universal IN
