Cannot detect Javelin Stamp and it is Hot
Gosh!! can someone help me out? i just bought a Javelin Stamp module and inserted it onto Board-of-education, which i previously bought as a complete robot kit with Bs2sx module. After replacing the Bs2sx module with Javelin, i cant detect it through Javelin Stamp IDE and the module was v hot.
what am i suppose to do? do i really need to buy Javelin own stamp demo board?

Few things to check:
Is the javelin inserted in the right orientation?
Do you get 5V between javelin pins 21 (VDD) and 23 (VSS)? If not, the javelin
on-module regulator is defect.
In that case you can try powering the javelin with 5V from the BoE
to pin21 of the javelin. Be sure to disconnect javelin pin24 (VIN) from the DIL24 socket.
If you feel uncomfortable doing that,·contact Parallax support first.
Do you use a USB BoE? What USB2SER cable do you use?
Have you installed the latest usb drivers?
Have you read this thread:

If the javelin still is not recognized after checking the above,
contact Parallax support for replacement.

Yes i am using a usb to serial cable for the connection. The Board-Of-Education is Rev C as printed on the board itself. I think (/not v sure) i have the stamp in correct orientation too, ie the circular-shaped regulator is closer to Vin and Vss of BOE after inserting.
I have installed the drivers too. Prior to replacing Bs2sx with Javelin Stamp, i did a final comfirmation using Basic Stamp Editor to do Identify check, it can detect Bs2sx on it.
I had also checked between javelin pins 21 and 23 it shows 5 volts, however, i still cant detect the Javelin with Javelin IDE.
for the switching regulator and it is indeed located near VIN.
So it is correctly oriented.
You could try to power the javelin via its pin21 as described (pin24 disconnected).
That way the javelin gets a regulated 5V from the BoE.
If that still leaves the javelin unrecognized, contact Parallax support
for replacement.

insert the javelin in a DIL24 socket, from which pin24 is cut off.
Then insert this socket with the javelin into the BoE socket.

What does this mean?
and select tab Debugger.
Select the com port assigned to your usb cable.
Add the comport if it is not listed.
Then click ok to close the option window.
Try identifying again.

pin2 (SIN) and pin4 (VSS) of the DIL24 socket on the solderside of the BoE board?
Without it the javelin might not be recognized. The MUST-READ thread I posted
few posts back explains why.
If that doesn't resolve the issue, you·should contact Parallax support
for a replacement.

I hv attached pictures of my boe. Will Bs2sx module works with the soldered resistor if i wish to use back?

The javelin does get warmer than a BS2sx but that is normal.
If you can detect the javelin now, as you say, and you can download
programs to it, I think it will be ok. Conclusion must be that there was
a bad contact between javelin pins and socket pins, that is resolved
by the multiple chip insertions.

I have also gone into the global-->debugger tab to try and the com port. But·i am unable to input into the COM port textfield, nothing appear in the textfield for whatever things i hit on the keyboard.

Anyhow, here you can download the latest FTDI drivers
