I buy the PiCrawler and now one servomotor ist not working, idk is this a good product or not?
Which servo is broken? Please connect that servo to a different PWM pin, or connect a different servo to the same pin, to determine whether the issue is with the servo itself or with the Robot HAT.
Also, before moving the PiCrawler, calibration is essential. The PiCrawler requires coordinated movement of all four legs and twelve servos, so precise calibration is critical. If any leg is not properly calibrated, it may cause excessive strain on a servo, potentially leading to damage.
