I grabbed some dial calipers and measured that the outer diameter of the barrel power jack for the UDOO is 5.5mm. However, looking online to buy a new solder-able male barrel plug, I discovered that there are two inside diameters, 2.5mm and 2.1mm. I do not have access to my team's UDOO today, and I need to place an order. Which is compatible with the UDOO? I found a link to each type on digikey: http://www.digikey.com/product-detail/en/PP3-002BH/CP3-002BH-ND/2197312 http://www.digikey.com/product-detail/en/PP3-002AH/CP3-002AH-ND/2197311 Preemptive thanks for your help! hiddenhobbit
