2.3 BMD-300 series footprint compatibility and migration
Figure 3: BMD-340/341 and BMD-300/301/330/360 Footprint comparison
The BMD-341 footprint is identical to the BMD-340 and has been designed to allow for backwards
compatibility with the BMD-300, BMD-301, BMD-330, and BMD-360 modules with pins 1 through 47
of the BMD-341 directly mapping to the same pin numbers on the BMD-300/301/330/360. This allows
BMD-300, BMD-301, BMD-330, and BMD-360 modules to be placed directly onto the BMD-341
footprint for easy migration and enabling tiered product design. Care should be taken to follow ground
plane and keep-out areas if designing for modules with an integrated antenna.
Generally, all pin names and functions remain the same, except for some differences noted below.
Pins 48 through 68 of the BMD-341 footprint are new pads used for new features that are not present
on the BMD-300/301/330/360 modules, such as USB interface and additional GPIO and power
connections.
