Hi there I have just been looking at the Uno32 reference manual. I see it as a SPI port J8 like the arduino can that be used to burn the bootloader and program the chip with external programers or do I have to use the JP3 ICSP header I have a mircochip pickit3 programer but I would like to program it the other way with J8. If anyone can help me I would like to get one of these pcb's but not sure on the programing ports

J8 is purely for SPI. It is provided for compatibility with shields that require it.

Programming the chip directly requires a programmer like a PicKit3, ICD, etc.

There are bootloader update sketches available that will re-flash the bootloader "internally" with no extra hardware required. These are meant for upgrading the bootloader on an existing working board. If anything goes wrong with it you may well still need a hardware programmer to rescue the board.
