PAN1780 Bluetooth Module
4 Reference Design
The reference design, shown in the block diagram below, gives an example of how to use the
PAN1780, to get a J-Link SWD and an FTDI UART connection on just one USB Port (X2).
The reference design of the evaluation board, including the provided peripherals is inspired by
the design of the nRF52840 Development Kit from Nordic Semiconductors.
