Romeo v2.0 burnt

the Romeo, after being repeatedly used to drive 4 dc motors with this battery :

suddenly got damaged. The atmega32u4 gets instantly hot after switching the power on, and the board is no longer recognised as a usb device.
Would could have been the reasons? How to prevent this from happening in the future?
Any questions for clarification are welcome.

How do you drive the Romeo V2 power supply?
Though the M_VIN? Did you connect the power cable with other pins? Grey.CC

Grey.CC 2014-03-21 17:18:17 The red one is a bluetooth mate gold.
The code for the uno is something like:
[code]
#include <SoftwareSerial.h>
int pin1 = 4;
int pin2 = 5;
int pin3 = 6;
int bluetoothTx = 2; // TX-O pin of bluetooth mate, Arduino D2
int bluetoothRx = 3; // RX-I pin of bluetooth mate, Arduino D3
int i;
char command;
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
void setup() {
for(i=pin1;i<=pin3;i++){
pinMode(i, OUTPUT);
digitalWrite(i, LOW);
}
Serial.begin(9600);
bluetooth.begin(115200); // The Bluetooth Mate defaults to 115200bps
bluetooth.print("$"); // Print three times individually
bluetooth.print("$");
bluetooth.print("$"); // Enter command mode
delay(100); // Short delay, wait for the Mate to send back CMD
bluetooth.println("U,9600,N"); // Temporarily Change the baudrate to 9600, no parity
// 115200 can be too fast at times for NewSoftSerial to relay the data reliably
bluetooth.begin(9600); // Start bluetooth serial at 9600*/
}
void loop()
{
if(bluetooth.available()){
command = bluetooth.read();
bluetooth.println(command,DEC);
if(command == '0')
for(i=pin1;i<=pin3;i++)
digitalWrite(i, LOW);
if(command == '1')
for(i=pin1;i<=pin3;i++)
digitalWrite(i, HIGH);
if(command == '2'){
digitalWrite(pin3, HIGH);
for(i=pin1;i<=pin2;i++)
digitalWrite(i, LOW);
}
if(command == '3'){
digitalWrite(pin1, HIGH);
for(i=pin2;i<=pin3;i++)
digitalWrite(i, LOW);
}
if(command == '4'){
digitalWrite(pin1, LOW);
digitalWrite(pin2, HIGH);
digitalWrite(pin3, LOW);
}
}
}
[/code]
And the Romeo code is something like:
[code] int E1 = 5; //M1 Speed Control
int E2 = 6; //M2 Speed Control
int M1 = 4; //M1 Direction Control
int M2 = 7; //M1 Direction Control
void stop(void) //Stop
{
digitalWrite(E1,0);
digitalWrite(M1,LOW);
digitalWrite(E2,0);
digitalWrite(M2,LOW);
}
void advance(char a,char b) //Move forward
{
analogWrite (E1,a); //PWM Speed Control
digitalWrite(M1,HIGH);
analogWrite (E2,b);
digitalWrite(M2,HIGH);
}
void back_off (char a,char b) //Move backward
{
analogWrite (E1,a);
digitalWrite(M1,LOW);
analogWrite (E2,b);
digitalWrite(M2,LOW);
}
void turn_L (char a,char b) //Turn Left
{
analogWrite (E1,a);
digitalWrite(M1,LOW);
analogWrite (E2,b);
digitalWrite(M2,HIGH);
}
void turn_R (char a,char b) //Turn Right
{
analogWrite (E1,a);
digitalWrite(M1,HIGH);
analogWrite (E2,b);
digitalWrite(M2,LOW);
}
void setup(void)
{
int i;
for(i=4;i<=7;i++)
pinMode(i, OUTPUT);
Serial.begin(9600); //Set Baud Rate
Serial.println("Run keyboard control");
digitalWrite(E1,LOW);
digitalWrite(E2,LOW);
pinMode(2,INPUT);
pinMode(3,INPUT);
}
//String Buttons[17] = {
// "J2","J1",NULL,"S2","S1","UP","LEFT","DOWN","RIGHT","1","4","2","3","RZ1","RZ2","LZ1","LZ2"};
// // Buttons Nmes
void loop(void)
{
if(Serial.available()){
// String n = Buttons();
char n=Serial.read();
if(n != -1)
{
switch(n)
{
case '6'://Move Forward
advance (255,255); //move forward in max speed
break;
case '8'://Move Backward
back_off (255,255); //move back in max speed
break;
case '7'://Turn Left
turn_L (100,100);
break;
case '9'://Turn Right

Adam 2014-02-14 18:18:17 Hello Adam,
Sorry for the late reply,
The red one is a wireless?
You want to use UNO to make the remote communication receiver?
How do you drive these 4 motor? Grey.CC

Grey.CC 2014-01-29 04:33:54 Here are the pictures. The breakdown occurred after we put the boards together on top of each other. The lipo was connected to the boards via a breakout cable
Do you need a more accurate description? Adam

It looks like the MCU has been broken.
Could you attach a photo about your hardware connection?
It will help us know what was happened? Grey.CC
