3.2. WS2118-00 module connections
The WS2118-00 dual band module (Figure 2: " WS2118E00 board components" –
region A) has 2 RF signal connector. One is for BLE (region B), another is for sub-1GHz
RF(region C).
The microcontroller of BlueNRG-1 is connected to various components such as
buttons, and LEDs. The following table describes the microcontroller pin functions.
