Li-ion Power Pack/Charger – 2 Cell

The Li-ion Power Pack-Charger – 2

Cell is an integrated storage cell and charging system on a single 3” x 4” printed circuit board now available from Parallax. It’s compatible with most 18650-size Li-ion cells. Price is $49.99.

Features:

• PCB-mounted cell holders with on-board charging circuitry.

• Multiple power input/output options.

• On-board output fuse protection.

• Nominal 7. 4 VDC output; 8. 2 VDC maximum.

• Standard 3” x 4” PCB footprint integrates well with the Board of Education® (#28150), Propeller™ Proto Board (#32212), or any application needing a reliable power. supply with an integrated charging system.

• Automatic charge/discharge switching circuitry.

• Holds two rechargeable 3. 7 volt Li-ion 18650-size cells.

• Multiple LED indicators provide charge readiness information for each individual cell; status key for the LED indicators is printed on the board.

• Aggressive holders retain cells in any board orientation and in moderate shock environments, such as mobile robotic applications. Cells are not permanent and are easily replaced.

• Dedicated circuitry continuously monitors the charging process to ensure safety, efficiency, and to maximize the number of charge/discharge cycles of each cell.

NEXYS3

FPGS Board

Digilent, Inc., announces the launch of the NEXYS™ 3 board, the latest addition to their family of FPGA-based design kits. Featuring Xilinx’s newest Spartan6 FPGA, 48 Mbytes of external memory (including two non-volatile phase-change memories from Micron), USB and Ethernet ports, and other common I/O devices, the Nexys3 board is perfectly suited for academic and industrial design settings. Students and engineers alike can build circuits ranging from simple logic circuits, to CODECs and custom device controllers, to embedded processors without needing any other equipment and for less than the cost of a textbook.

The Nexys3’s high speed USB2 port provides board power, high speed FPGA programming, and user-data transfers at rates up to 38 Mbytes/sec. The USB2 port supports Digilent’s latest Adept programming software as well as all Xilinx tools, including the free WebPack™, Chipscope™, and EDK™ tools. In addition to FGPA and ROM programming, the Adept system offers automated board tests, a virtual I/O system that extends I/O capabilities using a PC-based interface panel, and simplified user-data transfers. The Adept application, an SDK, and reference materials are freely downloadable from the Digilent website.

A large collection of low cost peripheral boards — including more than 40 Pmods™ and several new Vmods™ — can add additional features to the Nexys3, including A/D and D/A converters, breadboards, motor drivers, displays, etc.

The Nexys3 board is priced at $119 for academic customers and $199 for all others. Volume discounts are available. Most orders ship the day they are received.
