22257 DevBoard is an open-source printed circuit board by les4675, from the les4675/CubeSatTimeCard repository on GitHub, published under the MIT licence. It is a 6-layer board of 213.1 × 99.1 mm with 97 parts on 168 nets, routed with 906 tracks and 438 vias.
It is built around the 74LVC1G17Z, BME680 and TPS562202DRL, with the TPS73633DBV and 61083-102402LF among its other parts. Its parts include 25 capacitors, 15 resistors, 11 ICs, 7 diodes and 7 connectors. It belongs with the microcontroller boards boards of this library.
Currently we have developed models from the top level overview of our time card, along with setting up the SOM. Our goal in the next few months is program the SOM to take in data from a GNSS through the CAN protcol and to fine tone the PLL with the atomic clock that we have aquired.

97 parts, built around the 74LVC1G17Z, BME680, TPS562202DRL and TPS73633DBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the les4675/CubeSatTimeCard repository on GitHub, at the commit this page was made from: the board is KiCAD/22257_DevBoard/22257_DevBoard/22257_DevBoard.kicad_pcb and its schematic KiCAD/22257_DevBoard/22257_DevBoard/22257_DevBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
