BC68&M66 Compatible Design
BC68&M66_Compatible_Design 24 / 31
The following figure shows the recommended compatible footprint of BC68 and M66.
Figure 16: Recommended Footprint of BC68/M66 (Unit: mm)
1. The modules should be kept about 3mm away from other components in the host PCB.
2. The circular test points with a radius of 1.4mm in the above recommended footprint should not be
designed in schematic and PCB decal, and these test points should be served as a keepout area.
3. The pin 52 of BC68 should not be designed in the recommended footprint for compatibility with M66
module.
