MK08 series Bluetooth module has two different models — MK08A & MK08B.
The diffenence between MK08A and MK08B is the antenna design.
MK08A integrates a high-performance high-performance PCB trace antenna.
MK08B uses a u.FL connector and requires an external 2.4Ghz antenna.
MOKO development team can assist customers in selecting high-performance antennas that suit your needs.
