Question with RGB Addressable Lights.

I am looking to build proof-of-concept.

I will program a software application for the Raspberry Pi Zero 2 Wifi and manged the RGB Addressable Lights:

  1. Raspberry Pi Zero 2 W: using this platform.
  2. At least one each (or up to three of each) 1+ RED, 1+ YELLOW, and 1+ GREEN: need to better understand types of Addressable Lights for the control: off, on, blink, etc.
  3. Rechargeable Battery for the Zero 2 W: what size and type of battery for the unit?

Yes, I may need and have to create 3D print case for all of the components, small and compact as possible, wearable, water proof, dirt proof, etc.

Needing to know pros and cons with these lighting options, need to know what is programmable for compactness and simplest to implement.

SMD LED - RGB APA102C-5050
BlinkM - I2C Controlled RGB LED
SparkFun LED Driver Breakout - LP55231
SparkFun CBI Light Pipe for SMD LEDs 5mm - Right Angle (100pcs Bag)
APA102C-5050 SMD addressable RGB LED (Cut Tape)
SparkFun CBI Light Pipe for SMD LEDs 5mm - Right Angle (100pcs Bag)
SparkFun Qwiic LED Stick - APA102C
10 Segment LED Bar Graph - Red
10 Segment LED Bar Graph - Yellow
10 Segment LED Bar Graph - Green
14-Segment Alphanumeric Display - Red
14-Segment Alphanumeric Display - Green
14-Segment Alphanumeric Display - YELLOW ???
SparkFun Qwiic Alphanumeric Display Kit

First several prototypes and then bulk orders, etc.

Thank you,

SparkFun Qwiic LED Stick - APA102C - COM-18354 - SparkFun Electronics should be the easiest to get going/tested/working; you can run through the guide here to see how it works

This Qwiic Cable - Breadboard Jumper (4-pin) - PRT-14425 - SparkFun Electronics will probably simplify wiring too

One thing to note is you may need to enable the i2c/SPI bus on the Pi (via config menu)

Thank you TS-Russell for your feedback.

I will try the Qwiic LED Stick, however it is out of stock and not available at this time.

What other items do I need with the RGB Addressable CBI LED 5mm Right Angle?

Does this comes with 4 LEDs or those must be purchased separately from the board?

Which SparkFun battery attachment unit can be used with the Pi Zero 2 W board?

Is the small form Lithium Ion Battery - 400mAh sufficient and direct plug into for the Pi Zero 2 W?

Sparkfun doesn’t really have a battery for raspberry pi but a USB power bank from Amazon would work.

It should be back in-stock within a couple weeks.

I don’t recommend the one you’re asking about…it comes bare

You’d need a board to mount them, and a power supply…and write code to control them

For the Qwiic LED Stick you need the Pi + battery and can use the example code to easily control 1-10 of the LEDs

We do carry this battery bank Dual-Port Power Bank with Digital Display and Integrated Cables - 10AH - TOL-23322 - SparkFun Electronics

This might work for you. They are already in a strip and you can cut it to however long you need.

Is there example with Raspberry Pi for the Qwiic LED stick APA102C COM-18354.
And so, just follow the I2C Python method in the Arduino example?

These don’t use I2C.

Just google “raspberry pi APA102C” and you should get dozens of examples.
