• Connect the MODE_1 pin to the host controller to switch between command and
peripheral only mode.
6. (Optional) Status indication
Connect the BUSY, LED_1 and LED_2 pins to the host controller to allow easy indica-
tion of the status.
7. (Optional) UART flow control
Connect the /RTS and /CTS pins to the host controller in case the UART flow control
shall be used. This is mandatory for fast UART baud rates.
8. (Optional) Flash and debug interface
We recommend to additionally have the pins SWDIO and SWDCLK accessible in order
to support a fail-safe firmware update. A standard socket on the customer’s PCB for
connecting a flash adapter can be useful for debugging purposes (e.g. a JTAG 2*10
pin header with 2.54mm pin-to-pin distance).
If the module has to be connected to a PC, a converter (TTL to RS-232 or TTL to USB) has
to be used. See chapter
3
for details on all pins. Please refer to the Proteus-III-EV schemes
for a reference design.
The logic level of the module is based on 3V. A 5V logic level must not be
connected directly to the module.
4.2 Antenna connection
Proteus-III’s smart antenna configuration enables the user to choose between two antenna
options:
4.2.1 On-board PCB antenna
The Proteus-III has an on-board PCB antenna optimized for operation in the 2.4 GHz fre-
quency band. A simple short between the pins RF and ANT feeds the RF output of the
module to the on-board antenna of the Proteus-III. In this configuration, the module does not
require any additional RF circuitry.
4.2.2 External antenna
For applications that use an external antenna, the Proteus-III provides a 50Ω RF signal on
pin RF of the module. In this configuration, pin ANT of the module has to be connected to
ground and pin RF to the external antenna via 50Ω feed line. Refer to chapter
17
for further
information.
