Short Description

The idea behind this "device" is to create a common software and hardware design, to enable the advanced user to build a custom LED-Dimmer.

Soldering and PCB will be limited to Breadboard, so everyone who knows which side of the soldering iron will get hot can build it.

It will support a range of 1 up to 12 channels using the 16bit timer/pwm of the atmega µControllers.

Depending on the number of channels, it can be built into a REG-Case for central usage or into module case for decentral usage.

It will support CV (constant voltage) LED up to 24V and CC (constant current) LED.

Maybe for some configurations I (or someone else) will design a pcb.


While the current prototype runs on a Mega2560 Board, I plan switiching to SAMD21 on a ItsyBitsyM0 Board with MicroBCU and a PCA9685 I2C PWM Driver. With this setup 24 channels in a 9TE casing seem to be possible.
