This shouldn't be deleted. That's why the build is failing

The Limelight Systemcore is designed specifically with FIRST in mind. The Systemcore is powered by a Raspberry Pi Compute Module 5 (CM5), and uses a Raspberry Pi RP2050 for reconfigurable I/O.

It's not clear to me whether FIRST prefers "SystemCore" or "Systemcore"

I'm going to assume "SystemCore" because it is consistent with "MotionCore" and that's what FIRST used the most.

Per Jason's comment below, it should be Systemcore. wpilibsuite/SystemcoreTesting#119 (comment)


The SystemCore is a reconfigurable robotics controller that includes built-in ports for Controller Area Network Flexible Data-Rate (CAN-FD), Inter-Integrated Circuit (I²C) using a STEMMA-style connector, USB, Ethernet, and 6 reconfigurable I/O ports.
The 6 I/O pins support Pulse Width Modulation (PWM), Digital I/O, and Analog Inputs to quickly connect the common sensors and actuators used in robotics.

The SystemCore comes shipped with 4 GB of RAM and 16 GB of EMMC storage, and also comes with a M.2 A+E key 2230 slot for connecting compatible peripherals over a PCIe 2.0 connection.

The controller features LEDs, a display, and an onboard IMU. It has an onboard quad-core ARM real-time Cortex‑A76 processor.
The SystemCore also comes with integrated 2.4 and 5 GHz WiFi and Bluetooth 5.0 with BLE, but that may or may not be used for FRC purposes.

I don't really like talking about something and then speculating about how it might be used. I'd tend to leave it out, and then document it once the caveats are known.
