Blumod BMD-200 Module for Bluetooth 4.0 LE

The blumod BMD-200 from Rigado is a powerful, highly flexible Bluetooth Smart module based on the
nRF51822 SoC from Nordic Semiconductor. With a ARM® Cortex™ M0 CPU, embedded 2.4GHz transceiver,
and on-module chip antenna, the BMD-200 provides a complete RF solution with no additional RF design,
allowing faster time to market. The BMD-200 provides full use of the nRF51822’s on-chip peripherals,
allowing for a wide range of applications without the need for an external host microcontroller; simplifying
designs and reducing BOM costs. With an internal DC-DC converter and a voltage supply range of 2.1V to 3.6V,
the BMD-200 can be powered directly from a coin cell or two AAA batteries with ultra-low power
consumption.

Clocks

The BMD-200 module requires two clocks, a high frequency clock and a low frequency clock.

The high frequency clock is provided internally by a high-accuracy 16-MHz crystal as required by the nRF51822
for radio operation.

The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock; or
externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption.
