== Using with companion MCU chipset ==

When the module is planned to be controlled with external microcontroller chipset, then the UART connection will be used.

The mandatory module pins to connect to external companion MCU are:
*UART_TX : module pin 24
*UART_RX: module pin 23
*Wake up: module pin 25

Optional pin to connect to companion MCU is RESET (module pin 2). Reset is active at low level.

It is recommended to add a 100nF capacitor on Reset pin: this will avoid any untimely reset of the product due to ESD discharges.

The others I/O pins can be left not connected.

== Power supply ==

To supply the module, connect to VCC pin 27.
;Recommended : 3V level with a minimum of 2.7V and maximum of 3.3V.

Internal decoupling capacitors on power supply line inside the module are already placed with capacitors values of 4.7µF and 100nF.

No need to add external decoupling capacitor on VCC pin 27.

We recommend to place a ferrite bead on VCC line: recommended reference is MPZ1608D101B from TDK.

;Impact of power supply level on TX power

The TX power is sensitive to external power level on Vcc.

Measure of TX power level depending of voltage level, and current consumption associated:

VCC=3.3V: Measure of Tx power on antenna pin=14.2dBm, I=43.5mA
VCC=3V: Measure of Tx power on antenna pin=13.65dBm, I=40.1mA
VCC=2.7V: Measure of Tx power on antenna pin=12.85dBm, I=36.6mA
VCC=2.4V: Measure of Tx power on antenna pin=11.83dBm, I=32.3mA (absolute low voltage level)
VCC=1.8V: Measure of Tx power on antenna pin=7.73dBm, I=24.5mA (not recommended)

== Antenna connection ==

On antenna RF pin 17, we recommend to place a pi matching network in order to match the impedance presented by the antenna connected to the board and the impedance presented by module antenna output.

The module antenna output is already matched to 50ohms in the frequency region band chosen.

ESD protection can be added to antenna port if the antenna is external to the product case. We recommend to use ESD8472MUT5G from On Semiconductor.

= Application circuit =

== Using with companion MCU chipset ==

When the module is planned to be controlled with external microcontroller chipset, then the UART connection will be used.

The mandatory module pins to connect to external companion MCU are:
*UART_TX : module pin 24
*UART_RX: module pin 23
*Wake up: module pin 25

Optional pin to connect to companion MCU is RESET (module pin 2). Reset is active at low level.

The others I/O pins can be left not connected.

== Power supply ==

To supply the module, connect to VCC pin 27.
;Recommended : 3V level with a minimum of 2.7V and maximum of 3.3V.

Internal decoupling capacitors on power supply line inside the module are already placed with capacitors values of 4.7µF and 100nF.

No need to add external decoupling capacitor on VCC pin 27.

We recommend to place a ferrite bead on VCC line: recommended reference is MPZ1608D101B from TDK.

;Impact of power supply level on TX power

The TX power is sensitive to external power level on Vcc.

Measure of TX power level depending of voltage level, and current consumption associated:

VCC=3.3V: Measure of Tx power on antenna pin=14.2dBm, I=43.5mA
VCC=3V: Measure of Tx power on antenna pin=13.65dBm, I=40.1mA
VCC=2.7V: Measure of Tx power on antenna pin=12.85dBm, I=36.6mA
VCC=2.4V: Measure of Tx power on antenna pin=11.83dBm, I=32.3mA (absolute low voltage level)
VCC=1.8V: Measure of Tx power on antenna pin=7.73dBm, I=24.5mA (not recommended)

== Antenna connection ==

On antenna RF pin 17, we recommend to place a pi matching network in order to match the impedance presented by the antenna connected to the board and the impedance presented by module antenna output.

The module antenna output is already matched to 50ohms in the frequency region band chosen.

ESD protection can be added to antenna port if the antenna is external to the product case. We recommend to use ESD8472MUT5G from On Semiconductor.
