Its a 2018-era laser mini board running Cluster firmware.
Hi Ray, asked this on twitter, but this might be a better way to reach you. Hope all is well in these weird times.
What’s the maximum sink current that the laser-fire pin can handle? I want to add a laser-fire indicator that will draw an additional 12-15ma. While I intend to put the indicator on the test-fire line, my PSU seems to cross connect them, so pulling low on laser-fire will also pull the test-fire pin low… but I don’t want to overload the laser-fire pin when that pin’s doing the pulling-low.
