Inchworm ICD is on RS232 please inform if there is a USB version and is this possible

Yes, the Inchworm+ can be mounted on a Unicorn which will turn it into a fast USB ICD2

Better yet build a Junebug (PICkit2) USB, fast and can program / debug most of the 16F & 18F chips.

But there is a difference ICD2 Programs more PIC than PK2 so if u remove MAX232 from Inchworm + and use USB then it will be a great combination.

and one more thing You have mentioned that Inchworm+ or PK2 doesnot support 3.5v devices so if we provide 3.5V power separately and take only
PGD, PGC and VPP out of ICD will it function. please tell
i want to use dsPIC with inchworm for programming only.

Added after 30 minutes:

How it could be done to make your ICD2 or PK2 3.3 volt .

Can u tell me the family, range or type of devices that are not supported by junebug( due to 3.3 volt).
you wrote all 18F series is programmable in Inchworm+ .

what about 3.3 volt ?

please tell

Both the genuine PICkit2 and ICD2 support 3.3v and 5v PICs, the extra parts required for the PICkit2 are in the schematic at the back of its manual. I left out the 3.3V as it would have increased the cost and complexity of the kit. funnynypd's PICkit2 clone has the 3.3v section.

Most of the 18Fxxxx PICs are 5v, there may be a couple of 3.3v only 18F but they are specialized ie Ethernet.
The 10F,12F,16F,18F & 33F are generally 5V PICs
24F & 30F are 3.3v only
Just read the specs in the PICs datasheet, some are only programmable at 5V but will run down to 3V.

What PIC did you have in mind?

Edit: I'm working on a 1.5A 5V / 3.3V power supply board (LM317) for the Junebug and Inchworm kits with level conversion.

Thanks,
I want to use dsPIC30F3014 in its data sheet ->electrical xtics

Voltage on VDD with respect to VSS ............................................... -0.3V to +5.5V
Voltage on MCLR with respect to VSS .............................................. 0V to +13.25V

can i use it without fear and also tell on which manual your's or microchip's that 3.3v section is present.

Is it means when i m programming it need 5V VDD when i put into real application then i require 3V.

The 30F3014 is fine at 5V, you can program at 5V some PICs even require it. The Inchworm can program and debug the 30F3014 the Junebug can only program it. (debugging may be added in a future release of MPLAB)

The 30F3014 runs fine at 5V.
