eb500 pins

Rob311

exactly what pins does the eb500 bluetooth module use?

the pin out specifies 123 5 and 7, but the programs use pin 6....

Jonathan

pin1 &2 = GND
3 = output
4 = input
5-6 Flow control, optional
7 = NC
8 = Connection status
9 = Mode control, data or command
10-19 = NC
20 = VDD

At a minimum, you need to use 2 Stamp pins connected to 3&4. Pin 6 would be used to tell the host to stop transmitting.

thank you very much Jonathan, i can probably decipher that into what i need, but just to confirm.
the pin out of the eb500 is as mentioned before. so if i plug my eb500 into my BOE, i can use pins... P7-P15 without confusing the eb500?

Jonathan

Not quite. Pin 9 will toggle the EB500 from command to data mode. Pin 8 will be high or low, depending on the connection status. You could bend or snip the pins. Pin 9 I never use, but pin 8 I use to make sure that I have a connection before I leave the init routine.

Ok, one more try then. i can use pins 10-15 (5 pins)?

Jonathan

Wait, I think we are missing a lil something here. I;ve been talking eb500 pinout. Using the appmod header on the BOE, pins 0-1 of the Stamp will be conected to pins 3-4 of the EB500. All the rest are offset the same.

So, with the Stamp, feel free to use:

2,3, if not using flow control
4,7-15
