7 segment displays The seven-segment display LD1 must have a common anode. Via R1 the brightness of the LEDs can be set, it should be noted, that the maximum current with direct control by the SPK2101.01 is 40 mA. Possible displays For big displays SA08-11SRWA in red, SA08-11YWA in yellow, and for small displays SA52-11SRWA in red, SA52-11YWA in yellow by Kingbright. - Page 15 StefPro - www.stefpro.biz - info@stefpro.biz - SPK2101.01 25.12.2022 Figure 14: Differences of display readability brightness level 25 The displays in figure 13 and 14 are from left to right: SA52-11SRWA SA52-11EWA SA52-11YWA SA52-11GWA SA52-11QBWA-D Figure 15: SA08-11SRWA left without and right with contrast pane with back light.
