Crazyflie 2.0: Radio range test

As you might already know we have added a 20dBm RF amplifier to the Crazyflie 2.0 as well as to the Crazyradio PA. We have had high hopes of getting a more stable link and much better range with this. We have done a lot of tests in the building we are sitting in and […]

Crazyflie 2.0: LED-ring expansion

A while ago we did a hack where we attached a NeoPixel ring to a Crazyflie. It was just a quick hack to show the concept, but we really liked the results. So we added some more firmware to easily be able to create new effects for the ring and also made it controllable using the Leap […]

Crazyflie 2.0: Qi inductive charging expansion

One of the boards that we have been working on is an inductive charging expansion for the Crazyflie 2.0. Some of you might remember way back when we did an inductive charging hack for the Crazyflie. It’s always been very compelling with wireless charging, we’re not sure why. Maybe it’s because it feels a bit magic For […]

New Crazyradio PA

As we said in previous post, with Crazyflie 2.0 one of the focus has been on enhancing the current Crazyflie platform. The radio range and power is one of these things that is good enough on the current Crazyflie but that could be made much better. So on Crazyflie 2.0 we added a +20dB power […]

Crazyflie 2.0 expansion port

One feature of the new Crazyflie 2.0 that we are especially happy about is the new expansion port. We have attached a lot of hardware to the current Crazyflie and we have also seen lots of users attaching their hardware, but it’s not very easy. The current connector is small, you will need to solder […]

Crazyflie 2.0 debug-adapter board

While designing the Crazyflie 2.0 one of our focuses has been enhancing the current Crazyflie functionality. As a flying development kit the current Crazyflie already has a JTAG debug port that allows to flash and debug the STM32F1 microcontroller. The design uses a standard ARM 10-pins cortex debug connector. The connector is shipped with the Crazyflie […]

Last week at Devoxx UK

Like we mentioned a couple of weeks ago we went to Devoxx UK last week exhibiting the Crazyflie. We got a chance to do lots of fun things, like flying the FPV quad in the keynote and also over the exhibition floor. The image is a bit faded, but we had the luck of having […]

Things happening in the community

It’s been a while since we summed up things happening in the community so here’s some of the things that are happening. There’s lots of more things, so if you think we are missing something, then post it in the comments below. Ralph has been doing some work on an semi-automatic flip feature in the […]

NeoPixel driver for the Crazyflie’s STM32

A couple of weeks ago we found the NeoPixel ring from Adafruit at a local shop, we had to attach this neat board to our copter and see what cool effect we could make with it. The ring has 16 RGB LEDs that can be driven independently with only one data wire. The LEDs the Neopixel […]

Brushless driver for the Crazyflie

A while ago I started working on a brushless motor control driver for the Crazyflie. I implemented most of it but did not really have time to test it. Recently we have gotten some request and questions about it so we took some time to do some further testing. Implementing a brushless motor control driver […]
