More EVB002 Files Posted

PCBCOM is an instructional document used in the GreenArrays factory to guide the testing, commissioning, and packing of the EVB002; if a board ever needs to be set up “from scratch”, this tells how to do it. This document may be found on the Index of Downloads page, in the Hardware Designs section. Another new file in that same section is EVB002-Datasheets-r0h.zip which is a collection of the component data sheets relevant to the EVB002.
