No Wire. No Limits.

LIGHTSPEED wireless technology is as fast or faster than many wired gaming mice. And that was the required benchmark for LIGHTSPEED viability. The only satisfactory result is the total freedom of wireless with absolutely no compromises.

1 ms Wireless Achieved

Logitech G engineers worked through a complete end-to-end technology optimization from sensor to firmware, circuitry to antenna. We tested and refined each component, focusing on the slowest link until nothing was slow.

  1. SPI: Sensor peripheral interface is highly optimized for maximum processing speed and efficiency to track motion precisely.

  2. MCU: Microcontroller unit translates data from the SPI, via enhanced firmware, faster than ever before.

  3. RFIC: Radio frequency integrated circuit transmits MCU data robustly and reliably via fine-tuned electrical pathways.

  4. RF antenna is designed specifically for LIGHTSPEED for absolute minimum impedance and maximum signal strength.

  5. Nano receiver connects discretely via USB and is fully capable of transmitting at a report rate of  1,000 Hz (1 ms) to the PC.
