This repo contains the KiCAD files for the PROVES Kit Antenna Board. This board currently goes on the +Z endcap of the satellite and hosts the antennas, interfacing ports, and some other support circuitry!
antenna_top_cap_board_v1a
This antenna board is a reformat of the V1 Antenna Board that consolidates a bunch of the 2pos Picolock and STEMMA connectors into a single connector that runs back to the V3b EPS Board. We are probably going to leapfrog this version to land on V2 which fundementally changes things about the antenna feed path.
antenna_top_cap_v2
This version of the antenna top cap featuers major changes to the antenna feed path and debug passthroughs. Notable features are as follows:
- Updated Balun Part Number (no longer sucks! still sucks to solder though)
- Addition of 12-pos and 5-pos Battery Board and Flight Controller Board debug connectors.

Questions
How big is the Antenna top cap v2 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Antenna top cap v2 use?
74 parts, built around the AS193-73LF, VL6180XV0NR/1, NCS1.5-232+ and BM04B-SRSS-TB(LF)(SN). 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.
Where can I download the Antenna top cap v2 KiCad files?
From the proveskit/antenna-board repository on GitHub, at the commit this page was made from: the board is antenna_top_cap_v2/antenna_top_cap_v2.kicad_pcb and its schematic antenna_top_cap_board_v1a/antenna_top_cap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Antenna top cap v2 design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
