Help needed with finishing and laying out a fairly simple MOSFET-based RGB LED driver in the form factor of an Adafruit Feather shield. I'm using the Adafruit Feather M4 Express to prototype and this will be a shield that stacks on top. I already have a working circuit I just need to transfer to PCB in Feather shield form factor and basic review. The Eagle schematic is mostly finished and I have begun board layout, but I could use help routing and laying out the board. The base PWM clock is quite high (40+ MHz) so I would like someone who has experience with high frequency digital signals to assist with trace width, optimal layout, bypass capacitor value and placement, etc. I believe this job could be a fairly quick turn around: help finishing the circuit, and layout & routing. I am using Seeed and Seeed's Open Parts Library with Eagle so experience with this is desirable ([login to view URL]).

Please look at these documents to get more clarity on the project.

Hi, I have experience in design DDR1 RAM on FPGA that clocked up to 200 MHz, also LVDS interface that clocked to 350Mhz. For your case, Actually there's nothing special treatment needed on PCB, because you are using PWM based signal which not interfere with another signal. but I can help you design PCB for it based on my experience. I have 8 years experience in PCB design and I have experience in high speed signal design. let's discuss the details over chat. update: I have read your update, yes I have experience using seed OPL, so this shouldn't be a problem. you have to add a resistor between adafruit and mosfet, to limit a current and anticipate a spike. Best Regards, Rijal
