JeeLabs LED Node v2 Kit


RGB LED Strips


Product Description

This product combines the JeeLabs LED Node with an RGB LED strip. For the LED Node alone, click here.

The LED Node v2 combines a JeeNode with 3 high-power (2A) mosfets. It is narrow (18 x 132 mm) form factor and has been designed as a good in-line fit for standard RGB LED strips.

The LED Node uses mostly through-hole parts, with the SMD MOSFET’s already soldered to the board, so it’s easy to assemble. It includes theATmega328, the RFM12B wireless module, 3 sensitive MOSFETs able to drive easily lengths of RGB LED strips (even types with 30 or 60 LEDs per meter).The MOSFET drive circuits are tied to I/O pins which support hardware PWM, providing independent flicker-free, dimming of each color. A 4-position heavy duty PCB termination matches the connections of standard RGB common-anode (common-positive) strips.

The LED Node takes its logic power from the required heavy duty supply (typically +12V regulated) which is passed on to the LED anodes. This design pays particular attention to handling relatively large currents effectively. There is provision for adding an optional thermistor for active monitoring of the MOSFET temperature, important when driving strips near the maximum (2A) recommended with high duty cycles. With more modest loading (lower maximum currents and/or duty cycle), the MOSFET’s typically stay just hand warm.

Read the ‘analog’ LED strip specification carefully. The series resistors embedded in the strip are there to limit the current draw of the individual series/parallel LED diodes. If in doubt, connect the strip directly to the power supply (that’s 100% duty cycle) and measure the current per color. The sum of these three currents must be less than the rating of the power supply and less than 3*2A, unless you add in the optional thermistor to detect and then limit excessive MOSFET temperatures. For extra long, single colour strips, the MOSFET outputs can safely wire in parallel.

Note that the LED Node does not have the full set of standard JeeNode’s “ports”. Two standard-wiring 6pin headers (Ports 1,4) are there in non-standard positions (board end and side).
