Hello, I have read that I can connect two mpu-6050 without requiering a multiplexer if they have differnet addresses, and for that I need to change the value of A0. A0 seems soldered to the ground on the Sparkfun breakout board, but right before this soldering there is a hole that I think is called solder jump. Does this mean that if I want to connect A0 to VDD, I just have to connect this wire to VDD ? Or do I have to unsolder A0 first ?
