actually we are cooperating the Microchip PICkit 2 team when we were designing the BB0703+ products.

We took many inputs from the original designers who cannot do it by themselves because of other reasons. We cooperate each other because this will benefit the end user, which is our common goal.

There are some unique features on our BB0703 family design and it helps some people to overcome the inconvenience when using PTG and provides best programming quality at all situation.

The original PICKit2 will work most of the time, no doubt on that. However there are many "experts" keep attacking the original PICkit2 design for not considering the USB voltage variation enough and leave some potential holes if the device is used for production purpose. The BB0703+ is designed to overcome that potential issue for production usage purpose. Plus the "BB0703+256K" now naturally support 256K EEPROM for PTG feature which is not available anywhere else.

Here is some feature compare list:

Basically, we don't directly compete with Microchip's PICKit2, we are the extension of their production line for customers who has special needs.

You are free to choose anything you like and express your thought/comments freely.

We have many BB0703 customers from Australia, please feel free to check out their reviews on the design and quality:

I'm actively against clones

Agree. clone will hurt the original designer and it is not a way to respect the original designer.

The BB0703 and BB0703+ are not as simple as clone, even people call them clones. smile.gif

And PICkit2 are open-source projects (actually we are working to modify some of the source code with the help of original designers) since the day it was born: full schematic, full source code are all available to the public. once you go with the open-source license, you can modify any thing you want, from the hardware to the software, just pick what you need.

The BB0703 was designed around Aug-2007, and enhanced feature are included, such as dedicated power supply for PTG, RJ12 Connector (makes it easily to be compatible with ICD2/ICD2/RealICE), etc. All components are SMD. With 20% of more components, our design team has made a PCB even smaller than Microchip's design, that's quite a challenge. Not even mention, our team designed the hardware in a more conservative way, so no "VDD pumping" is necessary on certain situation which are required on the Microchip design.

The BB0703+ was designed couple of month ago, it has all the features of BB0703, plus a buck/boost circuit which can secure +5V power supply at any normal USB voltage inputs (from 4.1V to 5.5V). the BB0703+256K naturally support 256K of EEPROM for PTG. Again, all components are SMD package, and there are 40% more components (60% of more components footprints) than Microchip PICKit2, and the size is still smaller than Microchip's design. Mission impossible, isn't it?

Everything is possible.

Enjoy your PICkit2 or BB0703/BB0703+. And have a nice day.

Just saw this Sticky Thread and wanted to add a tutorial site to it. The site below is the best one I have found for learning PIC microcontrollers for newbies. Start with the baseline PIC in assembly and work your way through. It is very detailed and you create simple programs that will come together to teach you the basics. The guy gives very good information on why to do things.
