5.1. Electrical Characteristics
ATBTLC1000 Xplained Pro can be connected to several Xplained Pro MCU boards and manually
connected to other hardware. Xplained Pro MCU board(s) that does not have 3.3V as it's primary target
voltage will read all ID devices on connected extensions to check if they support the target voltage before
enabling it to the extension headers. The table below shows the static content written in the ID chip.
