Overview
Scoring table hardware is an open-source printed circuit board by GrappleRobotics, from the GrappleRobotics/JMS repository on GitHub. It is a 2-layer board of 60 × 30 mm with 30 parts on 63 nets, routed with 262 tracks and 44 vias.
It is built around the MAX485ED, HT7533-1 and TC2050-IDC-NL. Its parts include 10 resistors, 8 capacitors, 4 connectors, 3 ICs and 2 diodes. It belongs with the robots and motor control boards and the STM32 boards of this library.

README.mdJMS
Another alternative Field Management System for the FIRST Robotics Competition.
JMS is based heavily off the official FRC FMS, as well as Cheesy-Arena. JMS differs in that the bulk of the network operations are performed onboard the JMS server itself, requiring minimal external and increasing the reliability of the system.
For those early-birds, do NOT install this on your personal machine. JMS WILL override your network, dhcp, and firewall settings. JMS is designed to be run on a Ubuntu Server 20.04 instance (either physical or in a VM).
More information coming soon.

Questions
How big is the Scoring table hardware PCB?
It measures 60 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scoring table hardware use?
30 parts, built around the MAX485ED, HT7533-1 and TC2050-IDC-NL. 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 Scoring table hardware KiCad files?
From the GrappleRobotics/JMS repository on GitHub, at the commit this page was made from: the board is electronics/scoring-table/scoring-table-hardware/scoring-table-hardware.kicad_pcb and its schematic electronics/backup-alliance-stations/backup-alliance-station-hardware/backup-alliance-station-hardware/backup-alliance-station-hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scoring table hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask GrappleRobotics before reusing the design.
