* #### CAN [<sup>note</sup>](https://github.com/Team4469/RAID-4469_2025/wiki/Glossary/#note)

  Controller Area Network - message-based protocol designed to allow microcontrollers and devices to communicate with each other’s applications
  \
  without a host computer.

### F

* #### FPGA

  Field Programmable Gate Array - is a type of configurable integrated circuit that can be repeatedly programmed after manufacturing. FPGAs are a
  \
  subset of logic devices referred to as programmable logic devices (PLDs). They consist of an array of programmable logic blocks with a connecting
  \
  grid, that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions.

* #### PDH [<sup>note</sup>](https://github.com/Team4469/RAID-4469_2025/wiki/Glossary/#note)

  REV Power Distribution Hub - latest evolution in power distribution for FRC. With 20 high-current (40A max) channels, 3 low-current (15A max), and
  \
  1 switchable low-current channel, the PDH gives teams more flexibility for overall power delivery.

* #### RoboRIO [<sup>note2</sup>](https://github.com/Team4469/RAID-4469_2025/wiki/Glossary/#note)

  The roboRIO is a reconfigurable robotics controller that includes built-in ports for inter-integrated circuits (I2C), serial peripheral interfaces
  \
  (SPI), RS232, USB, Ethernet, pulse width modulation (PWM), and relays to quickly connect the common sensors and actuators used in robotics. The
  \
  controller features LEDs, buttons, an onboard accelerometer, and a custom electronics port. It has an onboard dual-core ARM real-time Cortex‑A9
  \
  processor and customizable Xilinx [FPGA](https://github.com/Team4469/RAID-4469_2025/wiki/Glossary/#fpga).

### V

* #### VRM [<sup>note</sup>](https://github.com/Team4469/RAID-4469_2025/wiki/Glossary/#note)

  Voltage Regulator Module - provides access to different constant voltages for custom sensors, cameras, or other unique applications. 12V DC Input
  \
  Directly fed power from the Power Distribution Panel Designed to work with the roboRIO FRC control system.
