Monday 13, 2017 1. We started collecting information for all the shields used in the board (technical information, libraries and diagrams). We are planning to rebuild the board. Wednesday March 15, 2017 We start tracing the wiring for every shield (component installed in the board). -         Using the phyton programs used in each shield. -         Following the wiring in the board. -         Using the ohmmeter, to trace the wiring. Thursday, March 16, 2017 The relation of ports and shield used.
