im1WP | 1-Wire Interface Module with I2C bus, Lead Free. | CAD$12.95 In Stock |
|
Description
The im1WP is an electronic module with a I2C accessible 1-Wire interface, and press-fit connectors. It enables devices on a 1-Wire bus to be read and written to via an I2C serial bus. It has special circuitry to enable long distance communication on the 1-Wire bus. It uses the Dallas DS2482-100 I2C to 1-Wire Bridge chip. For details on DS2482-100, dowload it's datasheet from www.maxim-ic.com. The im1WP is part of the Modtronix Presto iMod product range.The im1WP has two rows of press-fit connectors on the bottom of the board. They can be pressed into 1.00mm holes on a 1.6mm thick (standard PCB thickness) target board. No special tool is required, they can be inserted by applying firm pressure to the connectors. Once fitted to the target board, the board is very secure, and can not be removed by hand any more. A screwdriver or similar tool can be used to remove the board if required. If the im1WP is to be soldered onto the target board, 1.10mm holes can be used. This will allow it to be inserted much easier than with 1.00mm holes. When using 1.10mm holes, the board can be removed by hand.

in28J60 | ENC28J60 Ethernet Module with SPI bus, PoE circuitry, 3.3V, Lead Free | CAD$24.95 In Stock |
|
Description
The in28J60 is a stand-alone Ethernet controller module with an industry standard Serial Peripheral Interface (SPI). It has a RJ45 connector with built in magnetics, LEDs and PoE circuitry. The module has press-fit connectors for easy integration onto a target board with no soldering required.The RJ45 connector allows power to be obtained via the network cable from either the two used pairs (pins 1,2,3 and 6), or the two unused pairs (4,5,7 and 8), as defined by the Power Over Ethernet (PoE) standard. Provision is also made for a custom, cheaper implementation of PoE by routing power from the unused network pairs (4,5,7 and 8), via a diode, to the Auxiliary power pin of the module. This Auxiliary power can be used to power the target board (board is mounted on). For details, download datasheet below.
For details on ENC28J60, dowload it's datasheet from www.microchip.com. The in28J60 is part of the Modtronix Presto iMod product range.
The in28J60 has two rows of press-fit connectors on the bottom of the board. They can be pressed into 1.00mm holes on a 1.6mm thick (standard PCB thickness) target board. No special tool is required, they can be inserted by applying firm pressure to the connectors. Once fitted to the target board, the board is very secure, and can not be removed by hand any more. A screwdriver or similar tool can be used to remove the board if required. If the in28J60 is to be soldered onto the target board, 1.10mm holes can be used. This will allow it to be inserted much easier than with 1.00mm holes. When using 1.10mm holes, the board can be removed by hand.

Power Over Ethernet
Official IEEE 802.3af PoE ImplementationThe official IEEE 802.3af Power over Ethernet standard provides 48 volts DC over two of the four available pairs of the network cable with a maximum current of 400 mA, for a maximum load power of 15.4 W. The circuit required to convert this to 5V or 3.3V (done on PD – Powered Device) is quite complex and expensive. It is not implemented by this module! All four signals, that is POE+1, POE-1, POE+2 and POE-2, are required to implement IEEE 802.3af. This is because the PSE (Power Sourcing Equipment, like a switch that provided PoE for example) can provide power on either POE-1 and POE+2, or POE-2 and POE+2 according to the standard. The X1U and X2U connectors have to be assembled to get access to these signals. They are not assembled by default, as can be seen in picture above.
Proprietary PoE Implementation
A cheap and simple alternative to the official IEEE 802.3af implementation is to use the spare pairs of the network cable (pins 4,5,7 and 8 of network connector) for power. There are many commercial products available that use this method. An injector is required to put the power (normally 12V or 24V) on the network cable. This injector is normally located at the switch, and will place power on all cables that require it. The PD (powered devices) on the other end of the cable can than use this module to access the supply voltage on the network cable.
The figure below shows the circuitry that extracts power from the spare cable pairs. The signals are marked POE+2 and POE-2 in the schematic. The POE-2 signal (pins 4 and 5 of network connector) is routed to ground via solder jumper J3. This solder jumper is made by default. The POE+2 signal is routed to the Vaux pin on the X1 press-fit connector, via a 40V, 1A Schottky diode. Power sent via the spare pair on the network cable can thus be obtained via the GND and Vaux pins of the X1 and X2 press-fit connectors.
