Does anyone know if this module (normally used for connection to an Arduino development board apparently) will work with the internal RS232 header on an Amiga 2000?
It looks like it has an RS232 header on it but I'm not sure and not finding much info about it. If it will work it appears to be loads cheaper than a normal Serial -> Bluetooth adapter.

Maybe I'm wrong, but I don't see that thing as possibly having enough pins to have hardware handshaking (CTS/RTS DTR/DSR) which will probably limit what you can do with it.
EDIT:
look at the under side.
Looks like you get an RX, a TX and a VCC and GND, so no hardware flow control... It still may work but not for Amiga Explorer and probably not PPP/SLIP.

I was thinking just for Amiga Explorer so I could use my laptop instead of setting up a second PC next to my Amiga 2000. I can get one for ~$5 on eBay. Might be worth a shot once my Indivision and keyboard adapter come in.

good luck, I think you'll also need a MAX3232 serial conversion circuit to go from 12V to 5v.
also. it absolutely will not work with Amiga Explorer

Oh, I read Indivision and got all excited... OK, the ECS :)
I forgot to mention, if you get that working, you may be able to use my program without flow control. I'd have to add that as an option.

Hello,
The seller uses 'RS232' and 'TTL' interchangeably, not enough data is provided to determine if it's a drop-in replacement (the signalling voltages of RS232 can be triple+ that of TTL) If it's designed to interface directly to a microcontroller or Arduino using TTL, you'll probably need to use an external level shifter (such as an ICL3232 or MAX232) to use it on your Amiga's RS232 port
Also, as bbond007 mentioned, there's no flow-control capability so you'll only be able to use it asynchronously

I found this application here where they say:
"Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer."

that means max232

Ehh. I'm better off just grabbing a normal bluetooth serial adapter. I didn't even think of the fact it might not use RS232 voltage and completely forgot about the flow control lines.
