Boards can be build as Gen 1 to 1.7 now
Generation 1 High/low capability but then LEDs dim to about 50% between full and empty battery
Generation 1.2 LEDs are voltage stabilized High/low does not work, no LVP
Generation 1.5 unregulated LED voltage + LVP
Generation 1.7 stabilized with LDO + LVP
- version with LDO → High/low not possible
- version with LVP → High/low not possible
→ flash #define INDICATOR_LED_SKIP_LOW setting as well
LDO → constant brightness and color mix over full battery voltage
LVP → shuts down when battery low (2.93V without MCU, 3.3V with MCU used)
.
LVP chip shuts down at 2.93V voltage,
if the MCU is used for Aux control also the reverse polarity protection diode counts in with about 0.35V
- above 3.3V all LEDs on and below 3.3V all LEDs off

Production board and stencil ready
any color combinations are possible each LED could have a different color
.
LEDs as you wish colors and patterns
450nm blue, pink, red, orange, yellow, green, ice blue, WW, CW (the yellowish green is too inefficient)
new LED batch cooperator boards for 3 brightness levels made
[LED colors] (top are most efficient, bottom inefficient)
LED color and each single LED current based on my “medium 0.5mA” brightness level
green 19.1uA
blue 21.2uA
ice blue 25.2uA
pink 30.7uA
CW 38.7uA
WW 40.2uA
red 50.9uA
orange 124uA
yellow 206uA
my LED brightness scale is based on my Rainbow+WW boards total current while LEDs seem same brightness
basically I have 5 levels “1mA”, “0.75mA”, “0.5mA”, “0.3mA” and “0.15mA”
this does only reflect on rainbow boards with WW the total current drawn
on the boards the total current depends on used colors and brightness level (“0.15-1mA”)
.
I can also build a board with a current consumption you want
for example, you can order a “0.3mA” pink/green all 12 LEDs equipped
