LimeSDR GPIO Board

LimeSDR GPIO Board board

The LimeSDR GPIO Board is an expansion board for the LimeSDR family that provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays.

  • Provides bi-directional level shifted IO for GPIO 0-7
    • 1.2-5.5V IO on J2
  • Each IO has a high voltage and power Darlington drive stage
    • Acceptable rating 30V 300mA (0-4) 200mA (5-7)
    • Suitable for inductive loads
  • Input/Output are individually switch-able
  • LimeSDR form factor
  • Individually pluggable relay connections
