Modular Circuits Advanced Expansion Kit
012-16529B
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.
