INTRODUCTIONMOD-BT is development board with female UEXT connector, which can beconnected directly to Olimex boards that have male UEXT connector can work asbluetooth serial port via RS232.

BOARD FEATURES– BGB203HS06 – combines the Bluetooth RF part, protocol stack, Link Controller

(LC), Link Manager (LM), and Host Controller Interface (HCI) firmware of theBluetooth system specification in one SiP with embedded software. Togetherwith an antenna and a reference clock this device forms a complete Bluetoothsolution. Note that the chip comes with SPP firmware described in the stackdocumentation.

– On-board antenna

– Three types of power supply – 1.8V, 2.8V and 3.3V

– PCB: FR-4, 1.5 mm (0.062"), red soldermask, white silkscreen component print

– Dimensions: (35.9 x 18.8)mm ~ (1.41 x 0.74)"

ELECTROSTATIC WARNING

The MOD-BT board is shipped in protective anti-static packaging. The board mustnot be subject to high electrostatic potentials. General practice for working withstatic sensitive devices should be applied when working with this board.

BOARD LAYOUT

POWER SUPPLY CIRCUITMOD-BT is typically power supplied by UEXT pin 1 and pin 2 with 3.3V.

There are two more power supplies – 2.8V for Radio and 1.8V for the core.

RESET CIRCUITMOD-BT reset circuit includes pin 6 of UEXT connector, pin 43 (RESET_N) of U1 and C15 (10nF).

CLOCK CIRCUITQuartz crystal 13 MHz is connected to BGB203 pin 20 (XTAL1_SYS) and pin 19 (XTAL2_SYS).

JUMPER DESCRIPTIONThere are no jumpers on this board.

INPUT/OUTPUT

Status led (yellow) with name STAT – this led shows that +3.3V is applied to the board.
