Gao Embedded Rolls Out Update for Ti Dsp Evaluation Board - Gao 2812evm - II

GAO Embedded Rolls Out Update for TI DSP Evaluation Board - GAO 2812EVM - II

Toronto, ON, Jan. 2008 – GAO Embedded Inc. has introduced an upgrade to its TI Evaluation board. The newly developed board, GAO 2812EVM-II, is specially optimized for driving motors and control systems that are based on TMS320F2812 series DSPs. In addition, it uses an independent power supply for AD sampling thus avoiding EMI from the CPU core.

The new features and improvements to the GAO 2812EVM-II will aid rapid development. Further more, it can even be used as a control unit in a system.

Features include:

• On-board TMS320F2812 DSP, 32-bit fix-point Flash DSP, operating at 150Mhz

• 128K*16 bits on-chip Flash program memory, Flash encryptable

• 18K*16 bits on-chip SRAM

• 256 K*16 bits extended SRAM (basic configuration) (upgradable to 512K*16 bits)

• 512K*16 bits extended SRAM as program/data RAM

• 4K * 16 BOOT ROM and 1K * 16 OTP ROM on-chip

• 10M ethernet interface, compatible with NE2000

• 9 independent push button switches

• Eight LEDs, convenient for learning

• Power on reset & manual reset

• 1 RS-232 interface for PC communication

• 1 RS-485 interface

• 1 CAN2.0 provide interface

• 16 A / D inputs(12bit ,0-3v,80nS)

• 4 A / D outputs(12bit ,0-3v,80nS)

• 1 USB DEVICE interface, the USB standard to facilitate communication with the PC USB

• Audio input

• 12864 Chinese graphic LCD interface

• 1 DC motor control interface

• 1 stepper motor control interface

• 2 extended unshielded interrupt inputs

• 5 extended shielded interrupt inputs

• 8 digital input, 8 digital output

• On-board VL-Bus, data/address/control access terminals

• Provide CLK, CS2, CS2, CS6, RD, WR, CS1571, RS1581, EVA, EVB, IN1 ~ IN8, OUT1 ~ OUT8 signal testing points and debugging points

• Power supply through the jumpers can choose external power supply or power supply via the USB interface

• 4 graphic LCD fixed mounting hole

• 4 fixed mounting hole

• Interface/Driver circuit for DC motor and Servomotor

• Physical size: 220 * 160 mm

I would like to know if this power supply is compatable with this mother board?

my power supply is-

Technially yes, since it has an 12v 4-pin and a 20+4 for your atx v2.x spec. However why would you combine a low quality unit with a high-end motherboard?

It is not likely this unit can handle a 575W load and likely rated for max/peak wattage and is perhaps only a 300W unit at best.

I would get a unit that has better voltage regulation and can stand up to its rated power stated on the label.

This would be a better choice

SeaSonic SS-300ES 300W http://www.newegg.com/Product/Product.aspx?Item=N82E16817151055
it can handle +12v@288w/24A http://c1.neweggimages.com/NeweggImage/productimage/17-151-055-04.jpg

compare to the alleged logisys' +12v@25A max http://c1.neweggimages.com/NeweggImage/productimage/17-170-017-17.jpg which will not be as stable as the Seasonic and likely to crash your system

The reason I focus on +12v max over total watts, both GPU and CPU need +12v power, and manufacturers are not as honest with their product (ahem - logisys...) and try to push off old ATXv1.3 units (that have unnecessary high +5v/+3.3v rails) as ATXv2.x - which is demonstrated with the 300w seasonic with +12v@288W compared to the logisys 575W with +12v@300w alleged max (and not likely handle it with stable volts)

cheers

Sugar Prices May Stabilize as Demand Outpaces Supply (Update1)
March 25 (Bloomberg) -- Sugar will probably stabilize, after plunging by almost half in two months, as import demand outpaces global supply, Thailand’s Office of the Cane and Sugar Board said.
