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.

• RoboRIO ^note2

  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.
