UPD-board
About the UPD-board
UPD-board is an open source PCB design by uniclogs, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 140.7 × 86.5 mm, with 184 components from 33 distinct parts.
Other key parts include the MAX7310ATE+T, ADT7410TRZ, ADS1115IDGS, UA78M33 and U_RasPi_40pin. By type, the board carries 46 resistors, 28 capacitors, 27 diodes, 24 jumpers, 22 transistors and 15 ICs.
From the project
University Class Open Ground Station Hardware
This board controls all of the switching of power to components in the ground station. It accepts it's commands through an I2C interface on the Stationd computer.
The switching is acomplished through 3 I2C GPIO device setup as 24 output bits. The bits control mosfet switches provideing both 5VDC and 12VDC circuits.
The board also has an A/D to monitor the RF Power Amplifiers output power detectors. The characteristics of this power measurement is detailed in the power amplifier testing spreadsheet unfer RF-systems.
