This IDE version has been converted to a 100% through-hole component design.   Designed to be used with the 838-RTC module or an original BQ4847 RTC.

Features:

• Support for 2 physical IDE devices (Primary and Slave)
• Each device can have 4 partitions of 260mb each.
• Support for standard 40-pin IDE connector
• Support for Standard 44-pin IDE connector
  • 44-pin has power and ground already wired into the connector.
• 5v power and Ground via (This can be used to power a IDE2CF Card or IDE2SD Card)
  • 2-pin header
  • 4-pin 3.5 type Molex connector
• DC/DC 5v converter replaced standard LM7805 voltage regulator
  • This upgrade allows the card to run substantially cooler, an average of 40-50 degrees Fahrenheit cooler than the standard 1.5amp LM7805 with heatsink.
• Can use an existing 5v 838-RTC Module or original BQ4847 RTC.

Please note when connecting devices to the card you must choose either 40-pin IDE or 44-pin IDE.  Do not use both at the same time.

Packages:

• Assembled and Tested - includes a complete board assembled and tested (buyer must choose IC socket type and clock module type during the purchase process).

IC Sockets:

• Standard Dual-Wipe (which are spring or pressure type sockets for IC's)
• Machined Round Sockets

Real Time Clocks available (if in stock will display in options):

• 838-RTC Module IF AVAILABLE (Includes an assembled/tested 838-RTC with CR2032 installed)
• Original BQ4847 (IF AVAILABLE) by Texas Instruments or other manufacturers - Internal battery has passed voltage test.

CF Card Adapter:

• Single CF Card Adapter currently, plugs directly into the 40-pin IDE connector, does require power to be supplied by a Molex power cable (purchased as an option) or a standard 2 pin jumper wires.  This adapter will give IDE1-4 with each partition being 260mb.
• Dual CF Card Adapter.  This adapter plugs directly into the 40 pin IDE connector, requires power supply by the Molex power cable (purchased as an option) or a standard 2 pin jumper wires.  This adapter will give IDE1-4 on the Primary CF Card and IDE5-8 on the Slave CF Card, each partition being 260mb.

Power Cable:

• Female to Female 4-pin Molex (only 5v and Ground is connected) - This power cable will connect directly to a device that supports a 3.5 standard type of Molex connector.  Note - this power only supports 5v and is perfect for the CF Card adapter or SD Card Adapter.

Selected System:
This option is just to let me know what to configure the card for before shipping.
