Goplus2 with M5Stack core -> Motor to slow
-
I have a issue with GoPlus2 and a RC Motor.
If i use the motor on a raspberry with L298N Motor driver the speed ist very fast.
On M5Stack core with GoPlus2 and Full Speed 100 (+127) the motor runs 1/3 of the speed from the L298N. What's the issue in M5 GoPlus2 ? Why the motor is too slow ?
If i connect on the GoPlus2 a external battery with 7.4V it makes no difference.
Has anyone a idea, how i can drive faster my dc motor with the GoPlus2 Modul ? It looks like the issue is "not" on motor or power voltage side. Must be on GoPlus2.

@thealphaghost The MotorWriteSpeed is an int, which could be at least 255.
Could you try a number greater than +127 and see if this hack works?

Hi @teastain
128 reverse the direction from forward to backward
-
@thealphaghost OK! thanks for trying!
Good luck! -
The voltage output from the go2 is only 5V
-
WHAT? Really?!
Then thats my problem! I cant find this information in the docs. It make no sense, if i can connect a external 12V Batterie…
-
@thealphaghost when I tried running a 12v loco off a 12v battery I was only getting 5v out
-
@thealphaghost You COULD connect the L298N using the GPIO on the side of the Core Basic?
Or if you NEED the GoPlus2 could you use three of the GroveB outputs? -
Hello @TheAlphaGhost
have a look at the schematic here. Input voltage goes through the IN Power Buck DC-DC and the output is 5 V, which is used for servos and DC motors.
Thanks
