shawly Posted June 3, 2020 Report Share Posted June 3, 2020 (edited) So a while back I had the plan of driving RGB LEDs from my Xboxes LPC header with the help of an ESP32. Because of reasons we haven't really worked on that project any further yet. In the meantime @Ryzee119 created the OpenXenium project, which effectively makes things waaay easier than before as we can use the OpenXenium's SPI for communication with the ESP32. Now the only question is, where is the best place on the Xbox to take 3.3V from for powering the ESP32 and two single LEDs (+ some headroom for leds on the controller ports maybe)? Would it be safe to power that many components though the OpenXenium's or rather the LPC's 3.3V line? Also where can I take 5V from for the 24 LED pixel ring I want to put under the jewel?

ttsgeb Posted June 3, 2020 Report Share Posted June 3, 2020 I would pull power straight from the power supply. Depending on the draw of that LED ring, you might risk burning traces, which would be a huge pain to fix. This is looking down on the motherboard with the bottom of the image being the front of the xbox. 1 Quote Link to comment Share on other sites More sharing options...

With the 3v3SB line I could technically even power the ESP32 when the Xbox is off, that would make it possible for me to turn it on via the ESP32, that's neat. Thanks for the pinout image!
