Pin Assignments
Pin Descriptions
Pin Number Name I/O Description
1 VCC — Supply Voltage
2 RXD I
UART Receive Data Input. This is the input
line for the configuration commands as well
as data to be sent over the air.
3 TXD O
UART Transmit Data Output. This is the
output line for the configuration command
responses as well as the data received over
the air.
4 CTS O
UART Clear To Send, active low. This line
indicates to the host microcontroller when
the module is ready to accept data. When
CTS is high, the module is busy. When CTS
is low, the module is ready for data.
5 CMD I
Command Input. This line sets the serial
data as either command data to configure
the module or packet data to be sent over
the air. Pull low for command data; pull high
for packet data.
