The Project: A 5V power supply for three Raspberry Pi Zeros and a LoRa transceiver capable of communication at least half a mile away, to be used to power and commmunicate with the Notre Dame Rocketry Team's Launch Vehicle Identification System (LVIS) payload

 The team successfully designed and built a printed circuit board that provides power and wireless data transmission capabilities for LVIS. It also interfaces with a laptop to receive data from LVIS at a ground station located safely outside the launch field. The screenshot below shows the data received by the ground station during a test.

 The board is able to provide 2 amps continuously at 5VDC, enough power for three Raspberry Pi Zero single-board computers and three pairs of Inertial Measurement Units. The wireless transmitter has a range of at least half a mile depending on conditions but requires a clear line of sight between the transmitter and the receiver. Pictured below are the boards used in the ground station (left) and the payload (right). The only differences are that the payload's board has attached leads for a battery and the jumper clip visible in the middle of the board is in opposite positions on the two boards; otherwise the boards are identical.
