Is the in put 5V ac or 23V dc?

Can this board run 2 independent motors and does it have a built in H bridge(motor controller or just motor driver) to reverse the direction of the motors ?

Is this board comparable with the NRF24L01 transceiver? If so how can it be connected?

Do I need to add a Bluetooth module to use the Goble app with Romeo V2?

My 2 Cents, The Impedance is too low with 2 motors in parallel, Hook em up in series and u SHOULD be A1! Inductive Loads are weird like that! Speakers are the same way, they overheat Amps if the resistance is too low across the coil! U have em hooked up in parallel (From the way it sounds), which cuts resistance in HALF, Series will DOUBLE Resistance, reducing how hot that H-Bridge gets! BTW, a heatsink is almost always a great idea!!!

Thank's for testing. I now will use the Romeo V2 with 23V and USB connection.
/* It's a pity that you don't want to tell the community about the problematic part of the RoMeo BLE circuitry. We could learn from it. And the warning in Romeo V2 Wiki still exist. So further questions will arise from other first time buyers. */

Hello, on your website you wrote, that supply >12V via M_VIN while debugging destroys the Romeo (V2.2). In the schematics I couldn't find a problematic circuitry. So please, can you explain what will be destroyed and why? I want to understand it because debugging without (high) V_MIN would be challenging in my application.

Hi, I'm on OSX but I don't see the port show in terminal after resetting the board. Thanks

Hi, My RomeoV2 isn't showing a serial port when connected via USB. I have reburned the bootloader using https://www.dfrobot.com/for... but still unable to detect a serial port at all. LED L1 is blinking as well as the red power LED is continuously on -is it bricked? Thanks

If anyone is interested here is a library to simplify the code for controlling the motors in PWM

Leonardo external interrupt pin is D0~D3, you can connect a button on those one directly.

Hi,
I have build two 2WD robot using Romeo V2 controller board. I also have XBee 2mW PCB Antenna - Series 2 on both of them.
Now I want to establish a master slave communication between both of them. I have configured the Xbee's also.
Can anyone suggest me with some idea.
And how Serial1.available() (leonardo) works in this case for Xbee communication. Pls help me asap.

Thank you

Hi, sorry for the late reply, This is Romeo BLE Link http://www.dfrobot.com/inde...
