We need a design the circuit schematic and PCB layout for a Mediatek MT6771 SoC. We do not have reference design for this SoC, you have to provide it. We currently make game consoles called RetroStone2 based on Allwinner A20. We want to replace the PCB in our product for a new version (RetroStone3) based on MT6771. Board will need to have: - MT6771 SoC -6GB RAM - LPDDR4 -SD Card -Ethernet Port - 100M is ok. -WiFi + Bluetooth -2 x USB 3.0 - for perirals (or 4 x USB 2.0 if 3.0 is not possible) -2 x USB 2.0 - for perirals -18 buttons for the gamepad controls (GPIO or SI LCD connector -HDMI Port -USB Type C Port – For power (and data if enough host available) -eMMC – 32 128 256GB options -NGFF M.2 SSD connector (optional) -4 ADC channels. 6 bit or more. It's for joystick components. -LTE are NOT required. Board dimensions, buttons position, screw holes position, restrict areas and connector positions will be given and must follow precisely the reference to match our current mold, as the PCB will be use as replacement in an existing product. Best to keep same connector models, if connectors are different than the one in reference, then they must be positionned precisely such that they will fit in our product. Board dimension is 90*140mm, space should not be a problem. Please keep PCB layers to a minimum as to keep cost down. Engineer has to debug the board and make sure it works correctly and is responsible to correct any hardware mistakes or issues. Components need to be rohs. Please quote for : - Hardware Design service : schematic + layout + BOM + impedance control guidePrototype 8 - Software Development : Android 10 which will have to support the gamepad buttons for navigation. And support all perirals. - Board production, unit cost based on 2k units for first production.
