Data Sheet

1. 32K jumper:

Since P16,P17 are multiplex with external 32.768KHz oscillator, this jumper allows the

PRBMD02 to connected with the on board 32.768KHz oscillator.

2. LED & UART jumper:

This jumper allows the module to connected with on-board LED and the on-board

USB-UART chip. Connecting 5V allow PRBMD02 to be powered from USB.

Connecting 3V3 will provides a 3.3VDC to the rest of the board

3. TM Jumper

PRBMD02 goes into ﬁrmware programming mode if TM pin is connected to the 3V3 pin.

4. Reset button

Pressing this button to reset PRBMD02 module

5. USB-UART LED:

LEDs indicate UART trafﬁc, yellow LED represents TXD and green LED represents RXD

6. module LED:

LEDs connect to the LED & UART jumper, user can makes use of these LED by shorting the

jumper.

7. VBus pin:

The EVK can be powered by USB port, or a 5VDC can be applied to this pin to power up the

board.
