BitsyOSD is a full featured standalone OSD firmware with a modern design for the MinimOSD Hardware.
It was specifically created for Multirotors (FPV Racing), Aircrafts and Ground Vehicles.

Why another OSD?
There are plenty of OSD options out there but I needed an OSD that was easy to maintain but still had all the features that I wanted. That's why I created BitsyOSD - a minimal configuration OSD that works right of the "box" (yes, there is a box that you can print on your 3D printer).
The OSD itself has a fixed layout that provides all essential information and only requires configuration of the GPS.
BitsyOSD supports the standard NEMA GPS as well DJI's Naza protocol.
BitsyOSD also supports no GPS and displays GPS unrelated values - making BitsyOSD a all around solution.
Currently BitsyOSD implements the following values in a fixed layout that is configurable and can be easily adapted to your needs:
- Altitude (ASL, AGL)
- Heading (AGH, BGH)
- Simple Variometer
- Traveled Distance
- Home Heading Indicator
- Home Distance
- Flight Timer
- GPS Statuses
- GPS Coordinates
- Battery 1 Voltage Monitoring
- Battery 2 Voltage Monitoring
- Low Battery Alerts
- RSSI (*)
- New in 1.4: No GPS Mode - enables a super minimal OSD mode
Please be aware that BitsyOSD doesn't have any outside configuration possibilities and all setup needs to be done via the code base
You need a MinimOSD (duh!) and a GPS. Currently BitsyOSD supports any NEMA compatible GPS and the DJI Naza GPS.
I highly recommend to get the Micro MinimOSD Hardware which contains better filtering and additional inputs for Battery monitoring in a very compact size.
Get them from ReadyToFlyQuads (http://www.readytoflyquads.com/micro-minimosd).
If you have a DJI Naza Controller, you can use an Y-Cable to split the cable from the Naza GPS and directly connect it to the MinimOSD.
You don't need to be an code expert but I assume that you have the following things ready to go:
- Arduino IDE installed on your computer
- NodeJS installed
- GIT installed
- MinimOSD hardware
- USB FTDI TTL serial adapter
- GPS Module and connection cable
Next you need to download this project. Navigate to a directory where you want to keep the BitsyOSD code and clone the project via git.
git clone https://github.com/FPVTools/BitsyOSD
A quick hint: Connect the MinimOSD to a TV if you want to see whats going on with your MinimOSD during the setup process.
BitsyOSD is using several libraries that need to be installed to your Arduino IDE. Copy and paste all of the libraries found in
libraries/ to your Arduino's IDE libraries folder and restart the Arduino IDE.

Upload the font
BitsyOSD is using a custom font that needs to be uploaded to the MinimOSD. The entire font upload process is outside of the main code base to keep the size small.
Note: You need to redo this process if the font set changes in future firmware updates
Connect the MinimOSD via the USB FTDI TTL serial adapter to your computer and upload the file
font/fontupload/fontupload.ino via the Arduino IDE to the MinimOSD. If you have a screen connected, you should be able to see the current font set on it.
Open a command console and navigate to the folder
font/. Execute the following command and follow the on-screen instructions.
This process may take some time and you should see the new font set on your display if you have a screen connected.
Upload the firmware
Make sure the MinimOSD is connected to your computer via the USB FTDI TTL serial adapter. Open the file
BitsyOSD/BitsyOSD.ino and click
Upload in the Arduino IDE.
If you installed the libraries as well uploaded the font correctly, you now have a working MinimOSD with BitsyOSD.
This project also includes the break-out board schematics for Eagle. The break-out board follows the standard flight controller size of 32x32mm and routes all necessary hook up points to one header.
