====== Luma Nodes ======
Luma nodes are serially-addressable high-power RGBW lights. They are networked on a RS485 bus, so modules can easily be daisy-chained and controlled.


===== Current Models =====
==== Luma-1L-R4.1 ====
{{:luma:luma4.1.jpg?600|}}

Current model with onboard 1 10W RGBW LED and integrated heatsink.
==== Luma-3L-R4.1 [PRE-PRODUCTION] ====

{{:luma:luma-3l-4.1_sneak-peak.png?500|}}

Current model with 3 onboard 10W RGBW LEDs and integrated heatsink.
==== Luma-S-4.0 [PRE-PRODUCTION] ====
Current model for driving high-power RGB LED strips

===== Obsolete Models =====

==== Luma-1L-4.0 ====
Initial 10W RGBW LED model with RJ45 and screw terminal connectors mounted on the top of the board (current models have these components on the bottom). This model adds 4 constant-current buck drivers for each LED channel, an on-board led, an on-board heatsink, a temperature sensor, and a crystal for clocking at 16MHz.
==== Luma-1L-3.0 ====
{{:luma:9nodes.jpg?600|}}

Luma board with an off-board LED driven with discrete transistors and surface-mount current-limiting resistors. This model adds reverse voltage protection, a transistor-controlled fan output, and better heat dissipation for current-limiting resistors.
==== Luma-1L-2.0 ====

{{:luma:luma2.0.jpg?600|}}

The first Luma board to communicate over RS485. Uses current-limiting resistors and transistors to drive an off-board LED.
==== Luma-1L-1.0 ====

{{:luma:tinyrgb-bottom1.jpg?500|}}

Intial Luma prototype, also known as TinyRGB. Communication over I2C using Cyz_RGB, an alternate firmware for BlinkM modules.
