Pinout and detailed pin functionsEdit

DWM can be connected to the host board through the J1 connector. The following table reports the connector pinout:

Pin number	Name	Type	Description	Voltage	Note
1	BT_EN		Main power supply input	2.0 – 5.5V
2	WIFI_EN		Main power supply input	2.0 – 5.5V
3	UART2_RTSn		Backup power supply input (available on request)	1.8 – 5.5V	If not available, please leave unconnected.
4	WIFI_IRQ		Backup power supply input (available on request)	1.8 – 5.5V	If not available, please leave unconnected.
5	UART2_TXD		Ground
6	BT_F2		Ground
7	UART2_CTSn		Reserved for future use	-	Please leave unconnected.
8	WIFI_CLK_REQ(A)		Reserved for future use	-	Please leave unconnected.
9	UART2_RXD		Reserved for future use	-	Please leave unconnected.
10	NC	Open-drain output	Status indicator for backup power supply. Pulls down when power is drawn from VIN_AUX rail.		Can be left open or grounded when not used.
11	DGND	Open-drain output	Overcurrent/thermal warning indicator. Pulls down when either main power supply or backup power supply current exceeds its current limit (4A) or die temperature of internal switch (130°C) is close to thermal shutdown.
12	NC	Open-drain output	Status indicator for main power supply. Pulls down when power is drawn from VIN_AUX rail.		Can be left open or grounded when not used. When used, must be pulled-hi
