I have an vehicle, that should be controlled via a M5Stack Fire.
For the 2 DC motors and the servos I want to use a GoPlus2 module with it's built-in Akku. (I had one in my collection :-) )
It's working, but I found the system in instable because of power supply.
I use a 7.4 V LIPO akku - connected to the GoPlus2 module - DC input. (If I use power from USB the motors are not propper working - they are 6V DC motors.)
I'm not sure if the akku of the GoPlus2 modul is loaded from that input. The green LED is on, but if I disconnect the LIPO akku the LED remains only about 5s on - then off and the connected M5Stack Fire is off.
What does the green LED indicates ?
Power or charging ?
