I think that my Arduino Mega R3 board may be bad. While searching Amazon website for new board, I found Keystone Mega Plus board shown at Amazon.com: KEYESTUDIO Mega Plus 2560 R3 Board for Arduino with Type-C USB Cable, 1.5A Output, More Powerful MCU Contoller Board : Electronics Is this board good?
good for what? the differences can cause problems
I wish to make a robot that uses servos to move arms and hands. I thought that the Keystone board is better for servos.
I have one in a mechanical arm, works great for servos, just put 6.5V to the barrel jack.
Edit: Just be aware that it provides 5V to the servo pins.
