The Graphics Board lets you create a compact assembly with a 64x128 graphic LCD capable of displaying a range of fonts and/or graphs with a JeeNode (or JeeNode USB, or SMD Kit). Ports 2 and 3 are brought out to attach a variety of additional plugs if needed.
The backlight resistor is chosen such that on 3.3V, this display draws ≈ 6 mA, and on 5V it draws ≈ 19 mA.
There is a solder jumper on the board which normally connects the backlight to the PWR line. When connected to the IRQ line instead, software control allows simple on/off control or full dimming using PWM.
The Kit - Light option uses a Graphics Board with dark blue dots on a light blue background, which can still be read even with the backlight off. The kit has the 64x128 graphic LCD and backlight, all necessary components, and 4 6-pin male headers to connect a JeeNode.
The Kit - Dark option is the same kit, but the LCD has light blue dots on a nearly black background. The contrast is a bit higher, but it can't really be used with the backlight off.
The PCB only version contains just the board. No parts, no headers.
