Aeromax OSD
The AEROMAX is a MINIM compatible multi-function OSD built to a spec from the team behind MWOSD.
As a direct result of feedback from issues with overheating, reliability and noisy images on the genuine and
MinimOSD clones in popular use, they worked with one of the best suppliers in china to produce a new design to
not only significantly reduce these issue, but also to provide additional hardware support and expansion growth
for the future.
Recommended for use with BETAFLIGHT / CLEANFLIGHT / RACEFLIGHT and PX4/APM

There are many MinimOSD style clones out there – so why buy this one. What makes it worth the extra. Check
out why:

Key features:

•
•

It’s from the guys at MWOSD – probably the most popular OSD firmware in the world today
Far superior noise resistance from power fluctuations
Uses the newest AB7456 chip – generates far less heat and uses far less power than MAX7456 based
clones
Works down to less than 4v – VERY resilient to voltage fluctuations unlike normal MinimOSD clones
which lock up
Flat bottom form factor for easy mounting – Just some thick double sided tape
Standard 0.1” servo pins – Easy and simple to connect
Gold plated pin via – higher quality
Extra hardware support - protect your investment in the future
Direct hardware support for non-standard FRSKY RSSI such as d4R-ii

Updated MAX7456 compatible on-screen display IC
Flicker free screen updates
All the same features as the original – and more – and in a smaller package
35mm x 20mm size!
5V DC Supply that can tolerate up to 35v
Regulated and filtered supply – less probability of display noise from power
FTDI cable compatible pinout
Two LED indicators
Arduino bootloader – you can update this unlike some clones
Supports direct monitoring of 2 batteries up to 6s without modification.
Supports current sensor
Supports Analog or Digital PWM RSSI signal. Also FRSKY D4R-ii - unlike clones
Powered by Atmega 328P 16Mhz processor
3 wire camera / VTX connections – option to pass through power

BAT1 - Main battery voltage monitoring (0-28v)
BAT2 - Video battery voltage monitoring( 0-28v)
RST - Reset (connect to ground to reset)
CURR - Current sensor monitoring (0-5v)
RSSI - RX RSSI sensor monitoring (0-5v Analogue or PWM)
Vout - Video signal output to VTX
Vin - Video signal input from Camera
Vcam - Supply voltage between VTX and camera.
5V – Supply to / from board
GND – Ground
RX – Serial input to board
TX – Serial output from board
DTR – Serial reset for programming

Solder pad functions:
•

•

The FRSKY RSSI filter jumper pad enables the use of FRSKY high frequency RSSI signals from units
such as the D4R-II. Enabling this permanently is recommended. Standard 50hx PWM RSSI is
unaffected by this jumper. Additionally, Analogue RSSI usually benefits with smoother readings when
enabled.
VBAT1-VCAM jumper pad is used to link the main battery voltage connected from VBAT1 to the VCAM
connections for the video in and out. This can be used to reduce wiring in some installations. Ensure
connected items such as camera / VTX can operate on the full battery voltage if used.

Product notes:
•
•
•
•
•
•

This product is intended for DIY use
A level of technical expertise is required to assemble, install, configure and use
This is not a plug and play product
Soldering may be required
Not all cameras are compatible with OSD’s - check for suitability
No liabilities are assumed for its use, suitability of application or any consequence from its use of failure

WARNING

•
•
•

This OSD is designed to be powered by 5v only. It can sustain significantly more however connected
peripherals may not.
Any voltages greater than 5v should only be connected to BAT1 and BAT2 pins
The VCAM pins for video in and out are connected together. This is to enable pass-through voltage, if
required, to the camera. It does NOT reduce voltages to 5v or 12v.
