4.3.9 Headers
The MBLS1028A features a 40-pin and a 60-pin 100 mil header, which provide all unused signals and those which should be easy
to access. 1.8 V, 3.3 V, 5 V, and 12 V are available at both headers. The maximum current load of all four voltage rails is 3 A each.
Both headers share the total available power of the four respective voltage rails.
