Here is a drawing to show how to connect a PropPlug to my P8XBlade2.
You will need to also supply a regulated 5V to the P8XBlade2 since the PropPlug does not supply this. You can use any USB style power supply which outputs around 5V regulated. The on-board regulator will use this to provide 3V3 for the Propeller chip, plus some in reserve for your additional circuitry. While its a tiny regulator, you should be able to get at least 200mA provided you only supply 4-6VDC regulated input.
I've been so busy with other things etc that it's taken me way too long to build a couple more that I have had on order for ages. Sorry to those waiting
Building a few more over this w/e, so if anyone wants one please let me know here. A couple of parts are going to limit how many I can build this time around tho'.
Thought I would upload all the latest info in some zip files
P8X2B2jpg.zip contains board schematics etc
OSv114sd.zip should be unzipped and then all files copied to the SD Card root (root means home/base/top) directory
OSv114sc.zip has all the source files, the homespun compiler, and a bat file to compile them
BOOTv112.zip has all the source files for the EEPROM boot, the homespun compiler, and a bat file to compile them. The EEPROM file for the P8XBlade2 is BootP8X2.eeprom and has been programmed into your board(s)
Here are links to the Parallax Forums that you may find useful
Notes:
1. My P8XBlade uses a 12MHz crystal so it is safely overclocked to 96MHz. These zip files contain code specifically recompiled for the new speed.
2. To use any other P1 program/code, You will need to recompile the code with the top level using (change the existing _clkmode/_xinfreq/_clkfreq settings to
CON
_clkmode = xtal1 + pll8x '\\ for P8XBlade2
_xinfreq = 12_000_000 '''''''''' 12.00MHz '//
3. My P8XBlade supports either the PropPlug (or equivalent) or a "cheapie" USB-TTL Serial device to program the P8X2Blade's EEPROM using the normal tools such as PropTool etc. Note there is a link to select either PropPlug or "cheapie". This link either disables the on-board transistor reset circuit (for PropPlug) or enables it (marked QE for transistor enabled) for the "cheapie".
4. The USB-TTL CP2102 module on eBay from alice1101983 is known to work (see pic in the zip file for the correct image), and it's pinout matches my pcb so that you may power my board via the USB - you need to bend one pin - I have an on-board 3V3 regulator for regulating this supplied 5V. Note these USB-TTL while having a 3V3 pin, cannot provide sufficient power for normal propeller use.

This one uses my older CpuBlade but would be better suited to the P8XBlade2 since it has an on-board microSD socket.

This one uses my P8XBlade2.

Has the pricing changed much? I'm planning on ordering at least 2 (w/o SD) in a month or so.
I have updated my website clusos.com with more info.
I will send you a pm.
