Module Descriptions
DC Buzzer
The DC buzzer module produces sound when a DC
voltage is applied to the terminals. The buzzer is polarized
and will only produce a sound when a positive voltage is
applied to the positive terminal. When 2-3 V is applied, the
buzzer will produce a sound with a frequency of
2300 ± 400 Hz.
Speaker
The speaker module produces sound when an AC voltage
is applied to the terminals. The frequency of sound
produced is determined by the frequency of the AC
waveform. The speaker has an 8 Ωimpedance and is
connected in series with a 10 Ω resistor for protection.
Diode
The diode module contains a PN junction diode that
allows current to flow in only one direction. Current will
flow when a negative voltage is applied to the side of the
diode marked with the grey ring. The arrow on the diode
symbol indicates the direction of conventional current.
Solar Cell
The solar cell module outputs a voltage when light shines
on the solar cell. The solar cell works best when using the
sun or an incandescent lamp as a light source. The solar
cell has a rated voltage of 5 V and a rated current of
90 mA.
NOTE
•Do not place an incandescent bulb too close to
the solar cell as it is possible to melt the case.
•
Do not connect the solar cell to a power
source. This will permanently damage the
solar cell making it non-functional.

Two Terminal
The two terminal module allows an external power supply
or signal generator to be used as a voltage source. The
module contains a fuse that will trip when the output
current is greater than 2 A. The fuse will automatically
reset after a few seconds.
NOTE
The fuse only provides overcurrent protection. It does
not provide overvoltage protection. Set the voltage limit
of your power supply to 3 V to prevent damage to the
Modular Circuits components.
Bipolar Junction Transistor
The Bipolar Junction Transistor (BJT) module contains a
3-pin connector to insert a BJT transistor. The module
identifies the location of the emitter (E), base (B), and
collector (C) pins and which direction the flat side of the
transistor faces.
The kit includes two NPN (2N3904) and two PNP
(2N4403) BJT transistors, though any standard transistor
can be used with the module. Make sure to check the
pinouts on the datasheet when using other transistors.
MOSFET
The MOSFET module contains a 3-pin connector to insert
a MOSFET. The module identifies the location of the
source (S), gate (G), and drain (D) pins and which
direction the flat side of the MOSFET faces.
The kit includes two N-channel (2N7000) and two
P-channel (TP2104) MOSFETs. Any standard MOSFET
can be used with the module. Make sure to check the
pinouts on the datasheet when using other MOSFETs.
Experimental Setup
To connect to a module
Connecting a module to other modules requires a
physical and electrical connection (Figure 1):
1. Physically connect the module by slipping the peg
and notch on one edge of the module onto the
notch and peg of another module.
2. Electrically connect the module by inserting a
jumper clip into the clip holders.

with a jumper clip inserted.
