LeonI made a new base board for Lion32, a 4-layer one. In this board there is a ground layer and I mixed the sound channels, noise and digital sample output to a stereo sound output. It also features a 1MByte static RAM and a second serial port.
I ordered the pcb from PCBWay as I have done so far for all my projects and I am very pleased with their service and the quality of the results.
I received and tested the board, everything fine, 1MB ram available now and the system is more "quiet".
