Pin
Name
I/O
Description
1
GND
-
Power supply and signal ground. Connect to the host circuit board ground.
2
DIAG_TX
O
Diagnostic serial port output.
3
DIAG_RX
I
Diagnostic serial port input.
4
GPIO0
I/O
Configurable digital I/O port 0. An internal weak pull up is provided when configured as an input.
5
RADIO_TXD
O
Serial data output from the radio.
6
RADIO_RXD
I
Serial data input to the radio.
7
/HOST_CTS
O
UART/SPI flow control output. The module sets this line low to indicate it is ready to accept data from the host
on the RADIO_RXD or MOSI input. When the module sets this line high, the host must stop sending data.
8
/HOST_RTS
I
UART flow control input. The host sets this line low to allow data to flow from the module on the RADIO_TXD
pin. When the host sets this line high, the module will stop sending data to the host.
9
PWM0
O
16-bit pulse-width modulated output 0 with internal low-pass filter. Filter is first-order, with a 159 Hz 3 dB
bandwidth, 10K output resistance.
10
GPIO2
I/O
Configurable digital I/O port 2. An internal weak pull up is provided when configured as an input.
11
GPIO1
I/O
Configurable digital I/O port 1. An internal weak pull up is provided when configured as an input.
12
GPIO3
I/O
Configurable digital I/O port 3. An internal weak pull up is provided when configured as an input.
13
RSVD
-
Reserved pin. Leave unconnected.
14
VCC
I
Power supply input, +3.0 to +3.63 Vdc.
15
GND
-
Power supply and signal ground. Connect to the host circuit board ground.
16
GND
-
Power supply and signal ground. Connect to the host circuit board ground.
17
/RESET
I
Active low module hardware reset.
18
ADC0
I
10-bit ADC input 0. ADC full scale reading can be referenced to the module’s +1.8 V regulated supply.
19
ADC1
I
10-bit ADC input 1. ADC full scale reading can be referenced to the module’s +1.8 V regulated supply.
20
MISO
I/O
SPI master in, slave out function. This pin is an input when the module is operating as a master, and is an
output when the module is operating as a slave.
21
MOSI
I/O
SPI master out, slave in function. This pin is an output when the module is operating as a master, and is an
input when the module is operating as a slave.
22
/SS
I/O
SPI active low slave select. This pin is an output when the module is operating as a master, and an input
when it is operating as a slave.
23
SCLK
I/O
SPI clock signal. This pin is an output when operating as a master, and an input when operating as a slave.
24
3.3V_OUT
O
Module’s +3.3 V regulated supply, available to power external sensor circuits. Current drain on this output
should be no greater than 50 mA.
25
ADC_REF
O
Module’s +1.8 V regulated supply, used for ratiometric ADC readings. Current drain on this output should be
no greater than 10 mA.
26
WAKE_IN
I
Active high interrupt input to wake the module from timer sleep. Can be used to wake module on event, etc.
27
WAKE_OUT
O
Active high output asserted when module wakes from timer sleep. Can be used to wake an external device.
28
GND
-
Connect to the host circuit board ground plane.
29
RSVD
-
Reserved pin. Leave unconnected.
30
GND
-
Connect to the host circuit board ground plane.
