INTRODUCTION
MOD-BT
is development board with female UEXT connector, which can be
connected directly to Olimex boards that have male UEXT connector can work as
bluetooth 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 the
Bluetooth system specification in one SiP with embedded software. Together
with an antenna and a reference clock this device forms a complete Bluetooth
solution. Note that the chip comes with SPP firmware described in the stack
documentation.
UEXT female connector
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)"
