About the Openlst hw PCB

Openlst hw is an open source PCB design by harmalkar, published on GitHub. It is a 4-layer board measuring 50 × 43 mm, with 81 components from 36 distinct parts.

Other key parts include the LP2981-3.3, CC1110, AP6502, ASFL1-27.000MHZ and MIC803. By type, the board carries 32 capacitors, 27 resistors, 8 ICs, 6 connectors, 6 inductors and 2 diodes.

It belongs with the sensors and rf & radio designs in this gallery.

From the project

Open-source hardware and software for a satellite with a custom on-board computer to interface over I2C, SPI, and UART with a flash chip, IMU, barometer, camera, and thermal sensors. Built to fit within a 1U form factor.

OpenLST board for SEDS@UMD modified by Nathan Kerns. The latest version of Kicad 6 Nightlies is required to view or modify the design. Recent pdf exports of the PCB and schematic are available in the pdf folder, but may not be completely up to date.

BOM is automatically generated in KiCAD using "bomcsvgroupedbyvalue" script, and manually separated into formats seen in bom folder. openlst-bom.csv contains entire BOM, openlst-bom-digikey.csv contains Digikey components, and openlst-bom-mouser.csv contains Mouser components.
