Introduction[edit | edit source]
SBC Lynx can be populated with DWM WiFi/Bluetooth combo plugin to easily add wireless connectivity.
This application note describes how to enable these interfaces when working with XUELK 1.0.0
Limitations[edit | edit source]
DWM wireless module shares some signals with mezzanine board connector J53. Thus, when DWM module is used, the following signals must be left floating:
- J53.1 (UART2_RX_DATA)
- J53.2 (UART2_nRTS)
- J53.3 (UART2_TX_DATA)
- J53.4 (UART2_nCTS).
