If you are interested in something more powerfull but still open, have a look at XuLA 2 board. It is a XuLA with steroids; based on a Xilinx Spartan 6 FPGA. XuLA 2 board is available as well on this website.
This book is a fundamental guide to develop the skills necessary to write powerful VHDL code. The approach taken by this book is to provide only what you need to know to get up and running quickly in VHDL. As with all learning, once you have obtained and applied some useful information, it is much easier to build on what you know as opposed to continually adding information that is not directly applicable to the subjects at hand.
This book was written with the intention of being freely available to everybody. To support our work, a paperback version can be purchased from our on-line store. Alternatively, please consider a donation.
VHDL is an extremely powerful tool. The more you understand as you work and study with VHDL, the more it will enhance your learning experience independently of your particular area of interest. The concept of using software to design hardware that is controlled by software will definitely provide you with endless hours of contemplation.
This DC/DC step-down voltage converter is based on the MP1584 and it converts an input voltage between 4.5V and 28V into 0.8V to 18V. This Voltage regulator is capable of driving up to a 3A load with excellent line and load regulation.
This DC/DC step-down voltage converter is based on the excellent Monolithic Power System MP1584,
The MP1584 offers a wide 4.5V to 28V input range that accommodates a variety of use for several applications. A 100μA operational quiescent current allows use in battery-powered applications.
High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.
The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 1.5MHz, the MP1584 is able to prevent EMI (Electromagnetic Interference) noise problems.
Teensy (ver. 3.1) is a complete USB-based microcontroller development system based on a 32bit 70MHz ARM (K20P64M72SF1) that measure only 30mmX18mm.
The Teensy comes pre-flashed with a curtom bootloader that allows you to program it using the on-board USB connector. No external programmer needed. You can develop code for the Teensy in your favourite program editor using C/C++ or you can use the Teensyduino, the Arduino IDE.
The Teensy unite the power of a 32bit ARM processor with the easyness of the Arduino IDE programming enviroment (Teensyduino). Teensy is equiped with 64 kB of RAM, 256KB of Flash, tons of analog inputs, CAN bus, SPI, I2C and USB port.
