Arduino / OLED display for Mavlink telemetry
video for russian users: https://youtu.be/RXbNGYmCdYs
Used Arduino Nano / Mini / Micro or other with h/w Serial and OLED i2c display 128x32 (SSD1306) or another. You may use any your display with your library, sketch very simple.
Arduino RX pin connected to LRS / RC controller telemetry output (TX), e.g., TX pin QCZEK LRS.
Device display current telemetry data: gps coords, battery data, heading, alt and other. Store last data to eeprom and display on powered, if no fresh telemetry data. If telemetry lost, display last data.
Build: connect OLED display to Arduino on gnd, vcc, scl, sda pins; install libs from used_libs.zip; upload sketch; connect GND and RX pin arduino to GND and TX pins rc/qczek telemetry output.
Power on device. Enjoy, this is easy way to see last telemetry data on crash / lost your aircraft.
