Repair tools
Test and diagnose in your browser — results link straight to the fixes, guides and parts in the database.
Controller tester
Xbox, PlayStation and Switch controllers, steering wheels and pedals, flight sticks, arcade sticks, Guitar Hero and Rock Band guitars and drums, Buzz! buzzers, dance mats and Wii Remotes. Stick drift, buttons, worn pedal sensors, touchpad, motion and more — faults link to the device's board, parts and guides.
PlayStation UART error reader
PS5, PS4 and PS3: connect a USB-to-serial adapter to the console's UART pads and read its stored error log in the browser (the PS3's Syscon log too, including the yellow light of death). Every code links to its meaning, fixes, guides and the parts to check, with their datasheets. Clear the log and save read-outs to your repair log.
Xbox POST code reader
Xbox One and Series (Raspberry Pi Pico with PicoDurangoPOST) and Xbox 360 (Pico with our script, or POSTduino): see which start-up step fails, what it means and which parts to check.
UART serial monitor
Watch what an Xbox, PS4, Switch or any other board prints over UART. Pick the board and any of its known error codes are highlighted and explained as they appear. Download or save the capture.
