I have been looking to the diagrams for the uno32 and it dosnt say what type diodes are on the pcb it says in the manual that d4 to d7 are clamp diodes d2 looks like a sot-23 type d3 not sure is that a zener diode x4way? Dose anyone know that values or type of diodes these are.

If you download http://www.digilentinc.com/Data/Products/CHIPKIT-UNO32/chipKIT_Uno32_bysa_c.zip It contains a file chipKIT_Uno32.bom which you can open in wordpad. It contains a list of all the parts. Most of the diodes are schottky type. You can look them up on Digikey.com and get spec sheets for each.

This is a copy of the diodes used. D1 B220A DIODESMA SMA Diode
D2 BAV99W BAV99W SOT-323 BAV99W Dual Surface Mount Switching Diode
D3 NSQA6V8 NSQA6V8 SOT-323-5 Low Capacitance Quad ESD Protection Array
D4 BAV70S BAV70S SOT-363 High Speed Switching Diode Array
D5 BAV70S BAV70S SOT-363 High Speed Switching Diode Array
D6 BAV70S BAV70S SOT-363 High Speed Switching Diode Array
D7 BAV70S BAV70S SOT-363 High Speed Switching Diode Array
