I am fascinated by constructing one of these drones to test Bluetooth 5. Nevertheless, I am being put off by the minimum order numbers required by most prototype PCB makers. Are you looking to sell a spare printed slope circuit board (PCB) from your build?

What is the max working range of this quadcopter?

I want to link the quadcopter source code with the website, but the bluetooth pairing does not work well
what should I do?

is this design for quadcopter is still valid or we need to make changes in the design or components for better performance. and how much better performance we can get with the current design. as I check the video on https://www.youtube.com/watch?v=ySj3hlKUGd0. can we improve its performance than this video's performance. and any more suggestion are welcome. Thanks.

Hi, I'd really like to build one of these drones to experiment with Bluetooth 5. However, the min order quantities of most prototype pcb manufacturers is putting me off. Do you have a spare PCB from your build you'd be willing to sell?

I'm interested about your project,Thank you very much you can share it , but I have some problems, in the source code you provide. in main.c

static void services_init(void)

{

uint32_t       err_code;
ble_nus_init_t nus_init;

memset(&nus_init, 0, sizeof(nus_init));

nus_init.data_handler    = nus_data_handler;
nus_init.data_handler_ex = control_char_write_handler;

err_code = ble_nus_init(&m_nus, &nus_init,pre_defined_reg_data);
APP_ERROR_CHECK(err_code);

}

the ble_nus_init_t structure, there is only one element,but there are two elements in the code." nus_init.data_handler_ex = control_char_write_handler"

ble_nus_init() function is also more than a parameter.

Excuse me, what I need to do?

My English is not good Please forgive me

@jantore I saw your commit yesterday, thanks for making them open-source !

STL and STEP files for the 3D-printed parts are now added to the GitHub repository.

Hi Christopher,

Nice to see that you're interested in the project! We used the parts for the Crazyflie 1.0, which is now called Craziflie Nano it seems. Those parts work fine for 6mm motors. I think the battery for Crazyflie 2.0 is a better choice, as they are tested with more powerful 7mm motors. The same goes for the motor mounts, that are also designed for 2.0s 7mm motors. We switched to a 320mAh, 25C LiPo battery when increasing motor size, so that's also an option.

Hopefully I can to upload the step files within a couple of days, I'll let you know when they are on GitHub. Please be aware that these parts, depending on which plastic is printed, will not tolerate crashes as well as the Crazyflie parts do and might break quite easily. Because of that, you would maybe consider buying motor mounts from crazyflie.

This is an interesting an funny project. Thanks for open source it on Github ! Like you said, the powerful nRF52 can now replace my CC3D and NAZE32 boards with ease ;)

Do you use the DC motors, motor mounts, battery and propellers from the Crazyflie 1.0 or from the Crazyflie 2.0 ? Could you also provide the step file of the 3D-printed pieces ? Thanks !
