PIC-80 Breakout Board
This is a breakout board designed to accommodate PIC micro controllers in TQFP-80 package. Supported parts include classic PIC18s, PIC18 J-series, dsPIC30F, dsPIC33F, and PIC24s. All power configurations are possible. This 2-sided board is routed mainly on the top side; bottom is served as a ground plane making it work well up to the maximum clock frequency.
In Europe, this board is distributed by lipoly.de. Check them out – for Europeans, shipping time (and possibly shipping price) should be much better!
PIC-80 Breakout Board for older PICs
This is a previous version of a PIC-80 breakout board. It was designed for “Classic” PICs – PIC18F6722, PIC18F8722 and such. There is no configuration jumpers and no power options. It is cheaper, too.
Arduino UNO, DIP
This is ever-popular Arduino UNO R2 open source electronics prototyping platform equipped with Atmega328P MCU in DIP package. Brand new in standard Arduino retail packaging – board, box, warranty card and stickers.
ADuM4160 USB Isolator board, populated
This board breaks electrical connection between USB host and peripheral while allowing data to pass. Design is based on Analog Devices ADuM4160 USB Isolator IC. Supports full/low speed USB 2.0 compatible operation and peripheral side power up to 600ma. A useful addition to any PC-based test instrument, USB audio device, as well as any other USB application where elimination of ground loop or power line pickup is desired.
Solarbotics sells my boards. If you are in Canada, you may want to check them out for better shipping time and rates.
If you live in Europe, this board is also distributed by lipoly.de. Check them out – for Europeans, shipping time (and possibly shipping price) should be much better!

USB Host Shield 2.0 for Arduino
This is revision 2.0 of USB Host Shield. Thanks to new interface layout it is now compatible with more Arduinos – not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play!
This shield is shipped as a kit, containing populated and tested board plus a set of stackable headers, which you need to solder on the board. Fully assembled shield is also available.
This shield will work with standard (dual 5/3.3V) and 3.3V-only (for example, Arduino Pro) boards.
Arduino clones with standard connector layout, including ICSP connector, should work, however only BlackWidow has been tested so far.
If your Arduino clone doesn’t follow classic layout, take a look at previous revision of the shield.
The following device classes are currently supported by the shield:
- HID devices, such as keyboards, mice, joysticks, etc.
- game controllers – Sony PS3, Nintendo Wii, Xbox360
- USB to serial converters – FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers
- ADK-capable Android phones and tables
- Digital cameras – Canon EOS, Powershot, Nikon DSLRs and P&S, as well as generic PTP
Support for more devices is currently in development.
The shield is shipped from the United States.
If you live in Europe, there are two places that distribute it. First, this board is distributed by lipoly.de. Check them out – for Europeans, shipping time (and possibly shipping price) should be much better!
Second, the TKJ Electronics carries them as well. They also offer header soldering service for a small fee. They’re also a major contributor to the USB Host library – check their blog often!

Stackable 2×3 header
This connector is used in production of USB Host Shield 2.0 to connect to Arduino ICSP connector. It can be used for similar purposes (for example, making a programmer cable) or anywhere else where 2×3 0.1″ spacing female connector is required.
A match on a product picture is placed for scale and may be included at no charge with your purchase if requested. Actual match may vary.
Tactile switch, 6x6mm, PCB Mount
Simple SPST tactile switch, Omron B3F or similar.
Switch mode DC-DC step-down converter kit
This is a kit of parts to build a switch mode DC-DC step-down (buck) converter with output voltage of 3.3V, 5V or 12V, output current of 1A typical and up to 1.3A under certain conditions. Designed around Linear Technology LT1376 controller. All through-hole parts, easy to put together following detailed Assembly Manual (link below).

120ma 5V/3.3V step-up/step-down converter
This charge pump DC-DC converter takes an input voltage from 2.0V to 5.5V and outputs jumper selectable 5V or 3.3V supplying up to 120ma. The input voltage can be higher than, lower than, or equal to the set output voltage – switching between step-down and step-up modes is automatic. The converter has over-temperature and overload protections as well as optional shutdown and power good signals.

USB Host Shield for Arduino Pro Mini
This is USB Host Shield designed to be easily combined with “Mini” variant of Arduino Board, specifically, Sparkfun 3.3V Arduino Pro Mini. It will also work with other 3.3V Arduinos. Also, due to its’ small size it can be used as general MAX3421E breakout board.
This shield is fully compatible and supported by USB Host Shield Library. Arduino Pro Mini is not included.

USB Host Shield for Arduino
!
This is legacy product to be used with older and other “not so compatible” Arduino boards. For most other cases, the latest revision of the board is recommended.
This shield adds USB Host capabilities to popular Arduino platform. Comes in four different configurations (details in the article). Software support for new devices is constantly added; at the moment, code for USB keyboard and PS3 controller are ready with Bluetooth and digital cameras in the works. To learn more about the project, browse USB Shield category on this site.
If you are planning to use this shield with one of the “Big” Arduinos, like Mega or 2560, SPI signals would have to be rerouted, i.e., pins 13,12,11 of the shield should be connected to pins 50,52,51 of the Mega.
