2.0 Appendix 2: Cheapstat Information
General Instructions for building a CheapStat portable potentiostat.
1// Circuit Board
Send the Gerber files to a printed circuit board manufacturer, and order one or more of the CheapStat
printed circuit boards. The gerber files are available as supporting information, and updated versions
may be found on our website.
2// Parts List
Order the parts from a vendor such as digikey or Mouser electronics. See table S1 for a full list of parts.
Some of these components may be substituted or omitted. For instance, this device can function with a
wide variety of different flash chips.
3// Soldering
Solder all of the components onto the printed circuit board as indicated in figure S1. You can zoom in on
this schematic, or look at the gerber files and the photos below (S2 and S3) for further clarification. If
you do not have the appropraite soldering equipment, contract circuit assembly firms such as Sandberg
Industries (Santa Ana, California) can do it for you for a reasonable fee. Be sure to wear an antistatic
wrist strap when handling the components.
4// Mounting the board.
You will need to cut several holes in the enclosure (Fig S2 and S7) to handle the LCD display, USB port,
and control switch. This can be done with a dremmel rotary tool.
5// Programming the microcontroller.
On the circuit board, there are a set of six pins that can be plugged into a microcontroller programmer.
First, attach the cheapstat to a USB power source. Then, attach the microcontroller programmer. Finally,
upload the firmware files to the microcontroller (available in supporting information). This process
should take a few minutes. This is the final step of the assembly process.
6// Using the cheapstat
With the CheapStat plugged into the USB port of a computer, start the control software program. Use
the four way switch on the CheapStat to select an experiment mode such as Square Wave Voltammetry,
change the parameters, and run an experiment. Be sure that the control software is set to the correct
COM port.
7// Handling Data
Data from the cheapstat can be copied directly into Microsoft Excel, Open Office, or other spreadsheet
programs.

Figure S1 – Board layout. An Atmel XMEGA microcontroller containing a DAC and an ADC with precision
sufficient for voltage waveform generation and current quantification. An RS-232 chip provides an
interface between this microcontroller and a data analysis computer via a USB port. An op amp
feedback system sets the voltage across the electrochemical cell and supplies the voltage needed to
drive the electrochemical reaction.
54
Two and Three Electrode Potentiostat Appendix
Figure S2 – The front side of the circuit board has a mix of surface mount and through-hole solder
connections. Many of the components have a fine pitch, meaning that the electrical contacts are very
close together. Nevertheless, all of the components were placed by hand and soldered without the
assistance of a reflow oven.
55

Figure S3 – The reverse of the circuit board supports a three-line LCD display and a joystick, which is
used to select an experiment protocol, change its parameters, and initiate experiments.

Figure S7 – Key features of the device. The red wire should be attached to a counter electrode. The
green wire can be attached to a working electrode. The white wire can be attached to a reference. The
device is controlled with a four way switch, and there is a USB port on the side, which supplies power
and an interface with any netbook, laptop, or desktop computer.

PCB Assembly
Order PCB
Blank PCBs were ordered from PCBexpress.com. After registering, select the quantity of boards desired,
with two layer fabrication, and upload the Gerber files that are included in the Cheapstat zip file. For
prototyping, a leaded solder mask was selected, however if the boards will be assembled by students
with little training in soldering technique and safety, a ROHS compliant PCB would be desired and
recommended.
Assemble PCB
EagleCAD can be used to display the schematic and layout (.SCH and .BRD files, respectively). Using
these two views, determine part placement on the PCB, it is also helpful to toggle PCB layers in
EagleCAD to make part placement and values easier to determine. See below for reference.
The Below view was generated by showing only the Top, Dimension, tPlace, tNames, and tValues layers.
The prototype PCB was built using leaded solder and flux, however for student assembly, lead free
(ROHS compliant) solder and flux is recommended.

To program the circuit, first connect the AVRIPS mkII programmer to the PC via USB 2.0 port; do not
connect the leads from the programmer to the Cheapstat yet. Install two standard AA batteries in the
battery holder. On the power supply jumper on the Cheapstat PCB, select battery power by attaching a
jumper across the ‘BAT’ AND ‘VCC’ pins. To proceed with programing of a Cheapstat PCB, open AVR
Studio 5, click Tools, and select AVR Programming
78

Figure 18 - Click Tools and Select AVR Programming
NOTE: When a factory new AVRISP mkII is used for the first time it will require a firmware update, and
will prompt the user when the user attempts to use it for the first time.
After all firmware updates are performed, the user can select the correct programmer that is connect to
the PC via the “Tool” dropdown box, as pictured below. The serial number of the programmer should
also be listed as another means to verify the correct unit being selected, in the even that multiple
programmers are connected to the same PC.
After the correct programmer is selected, the device dropdown box will allow the user to select the
micro that they desire to program. Select ATXMEGA32A4 from the list
