TicTacLights Nano Colour is the RGB version of TicTacLights Nano, which also fits into a mini TicTac box. Just like the monochrome version, it uses a lithium polymer battery, alternatively it can be powered from USB. The LEDs are square and only 1 x 1 mm large.

This project uses the BlinkenPlus firmware on an ATmega162 controller.


The hardware is split onto two stacked PCBs, the main board and the power/data board. The main board (4 layers with blind vias) contains the LEDs, the microcontroller, the shift register ICs and the associated transistors and passives. It also contains the Micro-USB connector for mechanical reasons. The power/data board (2 layers) contains the USB to UART bridge IC, a switching converter (to generate the 5 V supply required for the RGB LEDs when using battery power) and battery charger IC as well as the MicroSD card slot. The two boards are connected through a 1.5 mm high fine-pitch connector.

Only the solder paste stencils changed for Rev. 1.1.
