LimeSDR GPIO 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
