2.4. Power consumption
The following power consumption data are based on a 3.3V power supply, ambient
temperature of 25°C and measured using an internal regulator.
• All measurements were completed without the SAW filter at the antenna
interface.
• All emission data were measured based on the TX_Burst_Test&RX_Burst_Test
mode

7. Design guidance
7.1. Module application circuit
Figure 10 Application circuit diagram
Note:
• Because the PB-03M does not have the reset pin, we can achieve the reduction by
power off, we can restore the module with a PMOS to achieve the reduction of
power off.
• TX&RX serial port line, 2 resistors are reserved, In series in the line. The 3.3V
voltage used to prevent the serial port affects the reset of the module.

7.2. Antenna layout requirements
• The installation position on the motherboard suggests the following 2 ways:
Scheme 1: Put the module on the edge of the motherboard, and the antenna area out
of the motherboard edge.
Scheme 2: Put the module on the edge of the motherboard, and empty an area along
the antenna position.
• To meet the performance of the on-board antenna, metal parts are not placed
around the antenna, away from the high-frequency device.

7.3. Power supply
• Recommended 3.3V voltage, peak current over 200mA.
• Power supply is recommend to use LDO; If the DC-DC is used, the ripple is
recommended to be controlled within 30mV.
• The DC-DC power supply circuit proposes to reserve the dynamic response
capacitance to optimize the output ripple with large load changes.
• 3.3V power interface it is recommended to add ESD devices.

7.4. GPIO
• Some IO ports are lead outside the module, if using, a proposed resistance of 10-
100 ohms on the IO port. This suppresses the overshoot and enables smoother
levels on both sides, helping for both EMI and ESD.
• The up and down of the special IO port should refer to the use instructions of the
specification, which will affect the start-up configuration of the module.
• The IO port of the module is 3.3V,if the main control does not match the IO port
level of the module, the level conversion circuit should be increased.
• If the IO port is directly connected to the peripheral interface, or terminals such
as pin header, it is recommended to reserve ESD devices at the IO port line near
the terminal.
