Supply +VCC pin with a voltage between 3.7 V and 12 V. The board is regulated to 3.3 V internally. Using more than 3.7 V supplies increases power consumption without any significant improvement in supply noise rejection.
Supply the photodetector with a maximum 2 mW optical power.
The analog output is available on the SMA connector
PD out
(50 Ω impedance). The TTL output is available on the SMA connectorTTL out
(50 Ω impedance).Adjust the detection threshold with the potentiometer (blue). The threshold can be monitored on the
MON
pin.
