This week I worked on testing PCB with Raspberry pi. Everything was working good until I connected with raspberry pi. The raspberry pi can produce about 2.5 amp of current max and we were using 1.5 regulator to convert 12v to 5v for raspberry pi. After figuring that out we change one of the regulator with larger current handler. Showen in this picture below. Aslo while testing there got stump upon a problem with UART communication. The USB of metro mini and UART communication circuit won't work while the circuit in mounted. It has to be removed for the USB from metro mini to work. Currently looking into that problem. Â
