This shield extends the usability of Arduino Uno for neurobiological experiments. Digital IO can be routed to all five BNC connectors and three of them has an alternative function: one analog output for waveform generation and two analog inputs. Optional light intensity and temperature sensors.

Applications:

• Realtime behavioral experiment control
• Gated PMT control, trigger modulation for visual stimulation

These two pieces of hardware were a tiny contribution to the first detection of gravitational waves by Laser Interferometer Gravitational-Wave Observatory (LIGO).

The Timing Comparator extension board has seven 50 Ohm terminated input channels receive 1 PPS signals at TTL level and converts them to LVDS signal. Four channel generates 1 PPS signals from LVDS at TTL level with 50 Ohm driving capability.

Six layers were used for the PCB design of the Duotone expansion board. It two analog outputs for generating duotone signals. Eight clock outputs are available for driving 50 Ohm lines. Additionally two RS-485 ports, LCD interface and general purpose digital IOs can be utilized.
