Hello Rongzhong, I have the issue that only one joint (13) of all joints is moving. The batteries are sufficiently charged and all motors are connected to the NyBoard, and I believe the wiring is correctly (even if it isn't more than one motor should move?). When I try to calibrate the servos no. 13 is the only one that rotates, same goes for when I type in a command. When I run Nybble.io I always get "FIFO overflow! Using last reading!" in the serial monitor. I also tried different settings on the onboard potentiometer. Thank you for your time and help!

Hello, I was wondering if anyone encountered the issue of having troubles to upload sketches to the board. I can't upload any sketch to the board without getting the following error message: avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x83 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x83 Error opening serial port 'COM3'.

I tried different USB cables and searched the internet but wasn't successful in solving the issue. I would greatly appreciate any ideas or help. Fox
