Hi!

You can connect the 5V to any free pin marked 5V on the bigquad deck. And the same with ground.

Thanks for the video, that clarifies it a lot. Did not think you had a Bolt at first, should have read the title better :oops: The ESC sound is as it should. The first three sounds are the startup sound and the two last are that they are receiving a signal. I would advice you to try the setup withou...

I checked the two Bolt's end they basically had the same problem. The STM32 was burnt and one of the mosfets that switch on the power to the ESC. My analyses it that the Bolt couldn't handle the current from the ESC and that is what burnt the mosfet. I don't really know why the STM32 broke though bu...

The FPGA on the lighthouse deck is a bit sensitive and we have managed to break some due to just applying 3.3V. So injecting any voltage above 3.2V on any pin seams dangerous. A possible solution would be to exchange the 3.0V regulator (U2, TLV70230) to a 3.3V one on the lighthouse deck if you are u...

Easiest is probably if you rewrite the ALT hold part and change it to Position hold. This mode is the hoverDecoder in crtp_commander_generic.c. You would have to scale the CPPM input properly. Without testing it, I think it would look something like this: if (extRxAltHold) { extrxSetpoint.thrust = 0...

Unfortunately we don't have those values either. There might be a chance of getting them from the sensor manufacturers. MPU9250: TDK (Invensense) VL53L0X: ST microelectronics PMW3901: Pixart For the motors pretty sure the manufacturer don't have any figure. My guess is that 10% of the motors would f...

Hi Tom, That is definitely strange. There are no HW differences between the two batches and it sounds a bit like the IMU (BMI088) is performing differently. You say they are jumping, is it mainly Z that looks affected and all four new quads show the same behavior? When flying manually the compliment...

Something has probably gone wrong during a flash update. Do a cold boot recovery: 1. Disconnect all power 2. Connect battery while holding power button until M2 starts to blink 3. M3 should also start to bling now and you are in cold boot bootloader mode. 4. Chose cold boot (recovery) tab. 5. Press ...

You need to adjust the VL53L1 timing budget as well. Check zranger2.c for an example. There is a trade-off in accuracy and range though. I suggest you to consult the VL53L1CX datasheet for more details. You can probably do this in multiranger.c (have not tested) // Init VL53 if (vl53l1xInit(pdev, I2...

We don't really have what you are asking for but from the schematics this shouldn't be to hard to figure out. The Flow deck sensor connects to the STM, which you guessed right.
