最近买了一块AM335x Starter Kit开发板,硬件资料可以从官网下到,但是原理图的版本是1.2B,PCB布局图的版本是1.2A,BOM也是1.2B,而且硬件原理图和PCB合板时差了一个电阻,请问下,有没有1.2B版本的PCB布局图?

Note: revision numbers x.yz with the same x and y numbers are the same PCB. A change in the z alpha character is a change to documentation or a modification to the base x.y board. Changes to x or y denote a different PCB.
所以,1.2A和1.2B是一样的PCB。
