    Good quality board. Works great for development of software using open source tools and phlilips bootloader. Only thing that is missing is that the Boot select (BSL) is done by jumper. This means that you can not utilize the Phillips ISP utility to execute code after download. Need to add same circuit used for the Reset control to the BSL pin then this would be a perfect development board. I get tired of inserting and removing the BSL jumper. The Phillips ISP application is designed to control both RESET and BSL lines using rs232 control pins. This allows you to execute your application after downloading. I plan on building a little add on board to allow the phillips bootloader to control BSL pin also. This will speed up development cycle.
