Maximum current at Servo port + custom pins?
I'm thinking of all kinds of modifications. So, question 1: if I put a custom servo instead of the provided one, how much current can I draw from the Servo port?
Question 2: I'd like to request a firmware that would support using the free pins of the Atmega. For example, send 0's and 1's to few pins or use them as Serial/I2C port? The reason why is because I would like to try:
using few servos;
modify servos and use torque feedback;
Thank you so much!
infact , the newest firmware is using 99.99% of ATmega328P Rom space , so there is no space for I2C/Serial port function .
And , of course , you can use custom 9g servo , or 1 normal MG995 servo , our DC can provide 5V/3A current , so dont worry of current~
I've put a 20 kg torque servo... around 3A peak current. So better if I make a separate supply + driving mosfet.
99% used rom of 32KB is a pity, though, sounds familiar. I guess, I'll try sending information through PWM.
yeah , maybe you should use another power supply for your servo
cause if you use all 3A of 5V , you will dont have enough power for machine~
