Hello,
I am using the Makeblock MegaPi control card and want to work 6 servo motors(SG90) same time but it’s just working 4 servos. Only working A6, A7, A8 and A9. Is the card broken or the problem about the voltage source?
Thanks for any help.
Problem to control servos with MegaPi

Wireless communication interface – for adding Bluetooth module or 2.4G module (require corresponding communication module)
Port 1 – motor driver interface for driving DC motor, stepping motor and encoder motor (require corresponding driving module)
Port2 –motor driver interface for driving DC motor, stepping motor and encoder motor (require corresponding driving module)
Port3 – motor driver interface for driving DC motor, stepping motor and encoder motor (require corresponding driving module)
Port4 – motor driver interface for driving DC motor, stepping motor and encoder motor (require corresponding driving module)
Port5 – RJ25 communication module interface for adding Bluetooth or WIFI which requires RJ25 (require keyset for MegaPi’s transferring to RJ25)
Port6 – RJ25 dual-digital/analog interface for adding sensors or input/output RJ25 modules (require keyset for MegaPi’s transferring to RJ25)
Port7– RJ25 dual-digital/analog interface for adding sensors or input/output RJ25 modules (require keyset for MegaPi’s transferring to RJ25)
Port8– RJ25 dual-digital/analog interface for adding sensors or input/output RJ25 modules (require keyset for MegaPi’s transferring to RJ25)
With each RJ25 adapter, you can control two SG90 motors

The megapi already has builtin a large number of servo control pins see http://learn.makeblock.com/en/megapi/ so it doesn’t need a breakout board to be plugged into a RJ25 port

Hi,
Here is the details about Maker’s platform.
Please have a check.
