Dear sir or madam, we are searching for a hardware design which can do a first design for our needed product. Highest priority is time. We expect rapid implementation. Here is the needed functionality: - CPU is Rockchip RK3308 (Audio-Out-connection with I2S to DSP/Amp) - SD Card Slot - Memory DDR3L (min. 520MB, opt. 1GB) - Ethernet via Twisted pair, Xingtera chipset ([login to view URL], model XCA923TRIBB) - Components for Amp STA339BW Amp: [login to view URL] To control the AMP/DSP from the board we need additional a soundterminal board from ST: [login to view URL] - Just for your information how the layout for the control could look like. - DSP analogue output via 3.5mm audio jack - Active power of amp -> socket for speakers 2x2 clamps (L+R) - Switch Amp on/off - 24VDC input via clamps Our goal is to get from you the schematics, gerber files and also the project file for Altium or Eagle. Before start of layout we want to confirm schematics and used materials. If you have any questions just let us know. Best regards! Thomas
