Currently available Shimmer sensing units are the:
ECG: digital front-end optimized for measuring physiological signals like ECG.
EMG: digital front-end optimized for measuring physiological signals like EMG.
GSR+: analog front-end for the measurement of skin conductance, along with a 3.5mm jack
for analog or digital input from an external sensor such as the Optical Pulse Sensing Probe
from Shimmer.
Bridge Amplifier+: a bridge amplifier, excitation source, and connector enabling force
measurement with Shimmer, along with connector and amplifier for resistance
measurement.
PROTO3 Series: a series of prototyping boards for connecting external sensors to the
Shimmer3.
Please refer to the Shimmer website for more information about new releases.
3.4.2. Multi Charger
The primary function of the Multi Charger (see Figure 3-11) is to allow for the simultaneous charging
of up to six Shimmers. The Multi Charger also has a Reset Button which allows for synchronised reset
of multiple Shimmers.

For further information, please consult the Shimmer Multi Charger User Guide available in the folder,
\Documentation\Hardware User Guides, in the Shimmer User Resources distribution or available for
download from the Shimmer website.
3.4.3. Shimmer3 JTAG Adapter Board
The Shimmer3 JTAG Adapter Board, shown in Figure 3-12, can be used by firmware developers for
debug and programming purposes. It can also be used to provide input signals from analog sensors
or for peripheral prototyping. It installs in-line with Shimmer Dock to enable use of 3rd party JTAG
programming and debugging tools. The Shimmer3 connector, labelled in the figure, should be
inserted into the Shimmer3 external connector and the Dock connector should be connected directly
to the Shimmer Dock. Alternatively, the board can be powered directly via the USB power-only
connector, for use without a Shimmer Dock.
