LED Display:

The LED display is composed of 7 LEDs, you chose the color of LEDs you want. By grounding pin 14 on the module you can chose between 2 display modes; wide range and narrow range. In wide range, each LED has a resolution of 1 AFR, the range of display is 11-16 AFR. In narrow range, each LED has a resolution of 0.5 AFR, the range of the display is 11-13.5 AFR.

Wide Range LED Output:

AFR	Lambda	LED1	LED2	LED3	LED4	LED5	LED6	LED7
AFR<11	Lambda<0.748	On	off	Off	Off	off	Off	off
11<AFR<12	0.748<Lambda<0.816	Off	On	Off	Off	off	Off	off
12<AFR<13	0.816<Lambda<0.884	Off	off	On	Off	off	Off	off
13<AFR<14	0.884<Lambda<0.952	Off	off	Off	On	off	Off	off
14<AFR<15	0.952<Lambda<1.020	Off	off	Off	Off	On	Off	off
15<AFR<16	1.020<Lambda<1.088	Off	off	Off	Off	off	On	off
16<AFR	1.088<Lambda	Off	off	Off	Off	off	Off	On

Narrow Range LED Output:

AFR	Lambda	LED1	LED2	LED3	LED4	LED5	LED6	LED7

13.5<AFR	0.918<Lambda	Off	off	Off	Off	Off	Off	On

Optional Temperature Display:

The module also supports 2 external LEDs to show the temperature of the Bosch LSU sensor. These LEDs are connected externally as there are no footprints on the PCB for them.

Heater Status LED 0	Heater Status LED 1	Sensor Temperature
On	Off	Cold
Off	On	Perfect
On	On	Too hot
