Is there any basic stamp working at 3.3V (instead of 5V)?

Caleb

I have an accelerometer sensor working at 2.8~3.3V. I am not good to use Propellor chip which is working at 3.3V. So I would like to stick with basic stamp. Is there any basic stamp chip or modules which can work at 3.3V range? I become sick·to learn Propellor or translate 5V to 3.3V spending too much time. Please help me.

There are no Stamps that run at 3.3V. You could easily provide a 3.3V regulator for power for your sensor. It's pretty easy to interface 3.3V devices to 5V devices. Look in the Propeller forum at the "top" of the subject list. There's a thread on interfacing 5V to 3.3V devices (http://forums.parallax.com/showthread.php?p=667581).

I think (Phil, correct me if I am wrong) that the MOBO stamp can operate at either 3.3 volts or 5 volts.

Yes, the BASIC Stamp 2pe Motherboard (a.k.a. MoBoStamp-pe) has a jumper-selectable Vdd of either 3.3V or 5V.

Does this mean that the 2pe Motherboard can not only working ang providing Vdd at 3.3v, But also can communicate with 3.3V for clock and SDA signal in case of I2P communication? If yes, this would be what I am looking for. Please confirm me if correct. Thanks,

If you jumper it for 3.3V operation, then all the I/O is also at 3.3V including any I2C communication.
Sorry about my previous comments. It's still true that the Stamp modules are only 5V, but the BS2pe Motherboard
is a complete development / production system and is designed a little differently from the 24 / 40 pin DIP modules.

Mike,
Thaks a lot!
