I received the <a href=\"http:\/\/41j.com\/blog\/2015\/10\/photodiode-amplifiers-transimpedance\/\">photodiode array<\/a> boards today and decided to have a quick play around. With a 10M feedback resistor they&#8217;re only outputting about a volt, this will work but the OpAmps have 12v rails so I might change the feedback resistor at some point. Too quickly test the board I soldered 4 of the Opamps in and wired the output directly to some LEDs, later I&#8217;ll look at acquisition options, including the 8 channel <a href=\"http:\/\/41j.com\/blog\/2015\/08\/ltc1859-8-channel-100ksps-10v-16bit-adc-arduino-shield-layout\/\">ADC board I&#8217;ve made<\/a>.
