7-segment display modules

7-segment display modules are typically used to show radio frequencies (COM and NAV), autopilot values (HDG and SPD), and other numerical values from the simulator.

Modules using the MAX7219 driver chip are the most popular. MobiFlight also supports displays using the TM1637 driver.

Warning

Some 8-digit boards use the 74HC595 chip as the driver, particularly when ordered from AliExpress. These boards are not supported by MobiFlight. Pay close attention when ordering and only purchase boards that use the MAX7219 or TM1637 chip.
