The Carrier Board is a re-wiring option which sits between a JeeNode and its plugs. It has exactly the right size to fit snugly in a compact ABS box, made of two identical plastic shells which click together.
The JeeNode (FTDI or USB) can be mounted with the connector facing either outwards or inwards. All four ports are re-routed to 11 different 6-pin header positions. This allows multiple I2C plugs to be connected to one port, for example, or to place all the ports on one side of the box. Simply populate the positions you need for your project. There’s also a spot for boards with two opposing headers, such as JeeLabs Room Board.
If the PWR/SER/I2C connector and the SPI/ISP connector are populated, then these too can be accessed from the other side of the Carrier Board. There’s a built-in FTDI compatible 6-pin interface, as alternative for the one on the JeeNode – or for the JeeSMD, which has none.
There is room for a standard AC or DC power jack, which can be connected as needed. By creating a slot in the top plastic shell, you end up with a power connection which is robustly secured to the Carrier Board. The power jack is not connected to the board, allowing maximum flexibility in connecting power.
For maximum expandability, all 19 I/O pins are brought out in a single row on one side of the Carrier Board. This lets you use this in combination with one or two larger boards. The JeeLabs Carrier Card is one such option, but you can also use plain perf-board for this purpose, since all connector pins are on a 0.1″ grid.
See this page for an overview of the numerous combinations possible with the Carrier Board.
The Board w/ Box option includes the Carrier Board, a set of Plug Headers, a 0.1 µF cap for FTDI, a 5.5/2.1 mm DC power jack and plug, and the grey plastic ABS box for which the Carrier Board was designed.
One small trace on the power jack pads has been cut – so you can ignore the details about the errant ground, in the docs, when hooking up the power jack. It might not be a bad idea to check again with a meter though to make sure the ground hasn’t been shorted when soldering.
The PCB only version contains just the board. No parts, no headers.
