Class 2 Bluetooth module - F2M03C2
Datasheet
The terminal marked USB_ON can be any free PIO pin. The PIO pin selected must be registered by
settings in firmware (contact Free2move) to the corresponding pin number.
6.2.5 Bus-Powered Mode
In bus-powered mode the application circuit draws its current from the 5V VBUS supply on the USB cable.
F2M03 negotiates with the PC during the USB enumeration stage about power consumption.
When selecting a regulator, be aware that VBUS may go as low as 4.4V. The inrush current (when charging
reservoir and supply decoupling capacitors) is limited by the USB specification (see USB 1.1 specification,
section 7.2.4.1). Some applications may require soft-start circuitry to limit inrush current if more than 10μF
is present between VBUS and GND.
The 5V VBUS line emerging from a PC is often electrically noisy. As well as regulation down to 3.3V and
1.8V, applications should include careful filtering of the 5V line to attenuate noise that is above the voltage
regulator’s bandwidth. Excessive noise on the 1.8V supply to the supply pins of F2M03 may result in
reduced receive sensitivity and a distorted transmit signal.
