New addition to my wearable LED accessories is A12. A12 is the same size as R48, uses the same microcontroller and battery, but with 12 full-color LEDs. A12 produces patterns similar to Aurora mini 18, but lighter and has a built-in battery holder in the back.
A12 comes with a non-rechargeable battery (CR2450) and a black cord (lanyard) to hang around the neck. The battery lasts for about 5 hours or more in continuous run.This is a kit version, which requires surface mount soldering, and PIC programming hardware such as PICKit3. If you dont have SMT soldering skill, or PIC programmer, there is a fully assembled version as well.
Features/Notes:
- 12 common-anode RGB LEDs.
- PIC24F08KL301 16 bit microcontroller @ 32 MHz.
- Each LED is PWM controlled in 128 gamma-corrected levels.
- Dimension: 1.9 inch diameter, 0.4 inch thick (including the battery)
- Powered by a coin cell battery (CR2450 or LIR2450).
- Battery will typically last about 5 hours continuously.
- 1x PIC24F08KL301 or 401 IC1
- 12x PLCC4 RGB LED (common-anode)
- 1x 10uF 10V MLCC C1
- 1x Tactile Switch SW1
- 1x Battery Retainer
- 1x CR2450 (Lithium) or LIR2450 (Rechargeable Li-ion) Battery
Firmware: A12-1.3.hex
