Wiring & Info
The OpenLager is easy to connect via async serial. Wire it as per the diagram (an example of an OpenPilot-style connector is provided). Remember to attach the flight board's TX to Openlager's RX pin!
OpenLager has an onboard regulator and can be powered with 3.3 - 5.5V (the regulator dropout voltage is low enough for the SD card to work properly at 3.3V input).
SD CARD MUST BE FAT16 OR FAT32 FORMAT. FIRMWARE MUST BE UPDATED BEFORE USING:
{
'startupMorse' : '',
'useSPI' : false,
'baudRate' : 2000000,
'preallocBytes' : 104857600,
'preallocGrow' : false
}
The crucial field to adjust is baudRate -- set it to the serial speed you'll use for logging. dRonin supports 115200, 250000, 1500000, 2000000, and 2470000 bits per second. Cleanflight prefers 250000 bits per second, etc.
The green LED is on constantly when powered, and the red LED blinks during card writing. After 200ms of inactivity, the buffers on openLager will be flushed. If power is suddenly removed, the file may not be complete in the filesystem; this can be changed by setting preallocGrow to 'true', though there may be some garbage at the end of the file in this case.
The firmware for openlager can be updated by placing the appropriate lager.bin firmware image on the card.
The Airbot OpenLager MicroSD Blackbox is designed for drone enthusiasts who want to enhance their flying experience. It's perfect for those looking to tune their drone systems and troubleshoot any issues. This compact device, with dimensions of 20x15mm and weighing just 2g, can be easily integrated into your drone setup. It allows you to record valuable flight data, ensuring you can analyze and improve your flights.
