The Micro Minim OSD is a compact on-screen display module designed for FPV racing and multirotor platforms, integrating an ATmega328P microcontroller and MAX7456 chip for real-time telemetry overlay. It is compatible with MAVLink for ArduPilot and MultiWii Serial for Baseflight/Cleanflight, supporting dual battery voltage monitoring up to 4S.

Features

  • ATmega328P microcontroller with Arduino bootloader for flexible firmware programming.
  • MAX7456 monochrome OSD chip for crisp, real-time telemetry overlay on video feed.
  • Dual independent power sections with LED indicators, supporting up to 12V input.
  • Direct connection pads for dual 4S battery voltage, RSSI (analog/PWM), and current sensor.
  • Compact footprint (16mm x 15.6mm) and lightweight (4g) for space-constrained racing builds.

Description

The Micro Minim OSD represents a refined, miniaturized evolution of the classic MinimOSD, engineered to deliver robust telemetry overlay functionality without onboard DC/DC conversion to reduce thermal load. Its core architecture centers on an ATmega328P processor paired with a MAX7456 video overlay IC, providing a stable platform for custom firmware such as MAVLink for ArduCopter or MultiWii Serial for legacy flight controllers.

Electrical design incorporates two isolated power rails with solder jumpers for configuration, accepting input voltages from 5V to 12V via a 500mA regulator. The board exposes critical test points and connection pads for dual battery voltage monitoring (up to 4S each), analog or digital PWM RSSI input, and external current sensor integration, making it a versatile telemetry hub for FPV and autonomous UAV systems.

Key Features

  • ATmega328P 8-bit microcontroller pre-loaded with Arduino bootloader for easy firmware updates via FTDI.
  • MAX7456 monochrome on-screen display chip delivers reliable, flicker-free telemetry overlay.
  • Dual independent power sections with LED indicators and configurable solder jumpers for flexible power routing.
  • No onboard DC/DC converter minimizes heat generation during prolonged operation.
  • Exposed pads for direct connection of dual 4S batteries, analog/digital PWM RSSI, and current sensor.
  • FTDI-compatible programming pinout and standard 6-pin ISP header for direct firmware flashing.
  • Solder Jumper for PAL video standard selection, ensuring global compatibility.
  • Ultra-compact PCB footprint (16mm x 15.6mm) and 4g mass optimized for micro and mini racing quads.

Applications

  • FPV racing drones utilizing F3, Naze32, or Flip32 flight controllers requiring compact OSD telemetry.
  • Micro and mini quadcopters where space and weight are critical constraints.
  • ArduPilot-based autonomous UAVs and multirotors needing MAVLink-compatible OSD for ground station telemetry overlay.
  • Legacy MultiWii, Baseflight, or Cleanflight builds seeking serial-based OSD integration.
  • FPV platforms with dual-battery setups (e.g., separate flight and VTX batteries) requiring independent voltage monitoring.

Frequently Asked Questions

What flight controllers is the Micro Minim OSD compatible with?

The Micro Minim OSD is designed for standalone use or integration with APM, Flip, Flip32+, and racing-oriented controllers like the Naze32 and F3 series. It supports firmware for MAVLink protocol (used by ArduPilot/ArduCopter) and MultiWii Serial protocol (for Baseflight, Cleanflight, and legacy MultiWii). Ensure your flight controller's serial port is configured for OSD data output.

How do I power the Micro Minim OSD and what are its voltage limits?

The module includes a +5V 500mA regulator, accepting a supply input of up to 12V. It features two independent power sections with solder jumpers to combine them if needed. For dual battery monitoring, you can directly connect two battery packs up to 4S each to the dedicated pads, with the OSD itself regulated to 5V operation.

Does this OSD support RSSI and current sensor input?

Yes, the Micro Minim OSD provides exposed connection pads for both analog and digital PWM RSSI signals, allowing signal strength display. A separate pad is also included for connecting an external current sensor, enabling real-time current draw and mAh consumed telemetry on your video feed when used with compatible firmware.

Why does this version lack a DC/DC converter and what are the benefits?

This iteration of the MinimOSD omits the onboard DC/DC converter to reduce heat generation during operation, particularly when powered directly from a flight controller's regulated 5V rail. This design improves thermal reliability in enclosed builds and minimizes potential electrical noise interference with sensitive video signals.

How do I program or update the firmware on the Micro Minim OSD?

Programming is accomplished via an FTDI adapter using the FTDI-compatible pinout on the board. The module also includes a standard 6-pin ISP header for direct microcontroller programming. You can flash custom firmware like the MW-OSD or MAVLink OSD variants using the Arduino IDE or dedicated flashing tools after connecting the appropriate serial interface.
