2.4 QN9080 Module
QN908x IC integrates a BLE radio, controller, protocol stack and profile software on a
single chip, which can provide a flexible and easy way to use BLE SoC solution. It also
includes a high performance MCU (32-bit ARM Cortex-M4F), on-chip memory, and
peripherals for users to develop a truly single chip wireless MCU solution.
Shown in Figure 4.
Figure 4 QN9080 Module Board
QN908x Module has MIFA antenna on front of board. So it can work without external
antenna. There is a RF connector that is with switch on RF front-end. You can easily do
RF test by connecting a RF cable to the RF connector.
2.5 GPIO and Arduino interface
On QN908x DK board, the connectors J4, J5, J6 and J7 provide all GPIO connection
output. And it is also compatible to Arduino board interface. The interface schematic is
shown in Figure 5.
