I have files for a simple altimeter, but the pcb was designed a few years ago. Now there are newer and smaller barometric pressure sensors and microcontrollers, and I need to get this redesigned. I also want to add a small LCD screen for data readout and I want a micro usb port for programming. I need this to be compatible with arduino firmware and packed into the smallest board you can make. I look forward to working with you. If this job is completed successfully, I will have several more projects like this in the near future.
Also, I will handle the programming myself, so this listing is for the pcb design only.
