6.3 BMD-300 Series Footprint Compatibility and Migration
Figure 3 – BMD-340 and BMD-300/301 Footprint Comparison
The BMD-340 footprint has been designed to allow for backwards compatibility with the BMD-300 and BMD-301
modules with pins 1 through 47 of the BMD-340 directly mapping to the same pin numbers on the BMD-300/300.
This allows BMD-300 and BMD-301 modules to be placed directly onto the BMD-340 footprint for easy migration
and enabling tiered product design. Generally, all pin names and functions remain the same, except for some
differences noted below. Pins 48 through 68 of the BMD-340 footprint are new pads used for new features that
are not present on the BMD-300/301 modules, such as USB interface and additional GPIO and power connections.
