Pin definition:

Pin	function	description
1	TXD_DC	SELECT boot for high power, this pin function is string n TXD SELECT boot for low power, this pin function is IIC DD
2	RXD_DD	SELECT boot for high power, this pin function is string n RXD SELECT boot for low power, this pin function is IIC DC
3	CTS	The effectiveness of serial flow control
4	RTS	The effectiveness of serial flow control
5	NULL
6	NULL
7	roil	PWM supports UART, IIC, and APP control
8	PWM2	PWM supports UART, IIC, and APP control
9	PWM3	PWM supports UART, IIC, and APP control
10	PWM4	PWM supports UART, IIC, and APP control
11	RESET	Hardware reset pin
12	VCC	Power supply (1.8-3. 3V)
13	GND	Power supply
14	PWRC	Down wake-up, when the AT instruction is needed in the connection state, the AT instruction mode can be expressed by keeping this pin low level, and the pin is AT instruction mode at high and low levels in the rice connection state.
15	ALED	Broadcast scintillation, frequent connection after connection (master and slave effectiveness)
16	STAT	UAKT communication mode: unconnected low level, high level after connection. IIC communication mode: no connection level, connect, disconnect or receive data will work in interrupt mode, interrupt down edge hold time 200ms

17	SELECT	UART or IIC select pin boot low level: IIC communication mode boot high level: UART communication mode. The default SELECT is suspended to high level: UART communication mode. When the user needs IIC, the SELECT pin should be grounded.
18	103	High and low levels can be controlled by APP
19	102	High and low levels can be controlled by APP
20	101	High and low levels can be controlled by APP
21	NULL
22	NULL
23	NULL
24	NULL
25	NULL
