Warning! Before you attempt to install this booster kit, make sure you know what you are doing and are properly prepared. NEVER power on the devices without proper cooling or the antennae all being properly connected! Failing to connect all antennae to the booster boards or providing them with at least some passive cooling may severely damage the chips on the booster boards.

NLD Booster kit installation for DJI Mini 4 Pro

Tools needed:

    • Soldering iron with a fine tip
    • Solder with a low melting point
    • Flux
    • Torx and Philips screwdrivers
    • Hot glue

 

Step 1: Remove the battery and unscrew the 2 torx screws under in the battery compartment under the drone and the 2 torx screws under the front obstacle sensors (be careful not to damage the gimbal). You can now remove the top shell of the drone by carefully undoing the clips from the side.

Note: Watch a YouTube video if you want to see how that’s done.

Step 2: remove the remaining few screws (3 to 4 of them) on the top piece off of the motherboard, remove the air in-take grill and undo the clip-on connectors gently. You don’t have to undo anything on the side with the antennae.

Note: There’s hot glue on the connectors. You might want to warm up the glue a bit first so that it’s easier to remove. Be careful not to damage anything.

Step 3: once the motherboard is no longer connected on one side, you can lift it up gently to the other side so you’ll have a good view of the battery connector. Undo the 3 torx screws that holds that little board in place. You don’t have the remove them completely, just make sure you can pry the board far enough away from the plastic so that you have a good view of the pins.

Note: there’s a black sticker covering the back of the battery connector. You can pry that off with some tweezers.

Step 4: Now you’re going to have to solder 2 wires. Place your drone with the gimbal facing away from you. The red wire (+) gets soldered to the left most pin and the black wire (-) gets soldered to the right most pin on the back of the battery board. See the photo below.

Step 5: you can now screw the battery board back into place. Afterwards you can put the obstacle avoidance sensors back into place as well.

Step 6: put the step-down converter board on the middle of the obstacle sensor mount (see photo below). Solder the red wire (+) from the battery board to the “IN +” pad of the step-down converter board and the black wire (-) to the “IN-“ pad.

Step 7: Place the booster board designated for the drone right below the DC step-up board. Solder a red wire (+) from the step-up board’s “OUT+” pad to the booster board’s “5V” pad and soldering a black wire (-) from the step-up board’s “OUT-“ pad to the booster board’s “GND” pad.

Step 8: gently remove the “ANT0” antenna from its socket. Be careful; there’s a drop of hot glue on there. Once removed you can proceed to plug that white wire to the booster board’s ANT socket right next to the “GND” pad.

Step 9: plug the antenna wire that was included in the bag and connect one half to the remaining antenna socket on the booster board and the other half to the drone’s “ANT0” connector.

Step 10: Put a battery in the drone and turn it via that white button at the bottom like you’d usually do. If all’s connected properly the LEDs on the booster board should start flashing. If they are then turn off the drone, remove the battery and reassemble the drone again!

Note: it’s highly recommended that you place a drop of hot glue onto all your solder points and antennae so that they don’t come undone.
