Micro Scisky: The 32bits Open Source Brushed Flight Controller

If you’re looking to upgrade the flight controller in your existing toy, or looking to build your own FPV quad with micro brushed motors, the Microsciky 32 board (STM32 32-bit ARM Cortex MCU)  is probably your best option. Really convenient FC, lightweight, powerful built-in brushed ESC’s, DSM2 and open-source Cleanflight support. Takes a little while to setup correctly, but them flies great.

These small brushed drones not requiere registration and meet legal standards in most countries. Micro drones are safer because of their small size and low weight is very difficult that you could hurt yourself or others. In the U.S. FAA registration rule, drones weighing less than 250g were considered low-risk and did not require registration.

Although there are a lot of cheap drones of this type ready to fly in the market, such as the excellent XK130, it is always more fun to build and configure your own flying machine tailored to your preferences using open source software.

Brushed Motor have only two wire control , are low cost , simple and inexpensive control electronics. Most all of the small toy-grade quadcopters are brush type.  The other type of motor is the brushless, way more powerful and the used one in professional drones, that does not mean that it is necessarily better. Brushless  are usually also larger and heavier so not available on micro and nano sized machines.

Toy grade quadcopter often have closed controller with very limited performance designed for kids and novice pilots. Would not it be great to have the advantages of  brushed motors in a real fast race drone? With Micro Scisky you could run open source Cleanflight (same as pro race drones) in a small but really capable quadcopter. Brushed quadcopters are fun to fly indoors with lightweight setups. Acrobatic indoor LOS flyers often use 6mm and 7mm brushed motors. The larger 8.5mm brushed motors are well suited for carrying FPV gear.

Micro Scisky is a small Naze32 with all the electronics to run bushed motors and ready to run Open Source Cleanflight ( https://github.com/cleanflight/cleanflight ) / Baseflight / Betaflight. Sporting a 32-bit ARM Cortex M3 processor board and has a micro USB connection, UART/I2C Bus, DSM2/DSMX compatible RX, integrated ESC and 5v DCDC voltage booster circuit to power external devices like FPV gear, GPS receiver o Bluetooth boards.  Here my last micro size quadcopter build, a very lightweight acrobatic LOS with 7mm motors.

Overall an afternoon worth of tinkering to get the Microsciscky flying. This works great! Much more power than expected using the cheap motors and props. Just add small video TX to turn into a nice indoor/outdoor FPV flyer.

J.Sheng  put a great video on youtube of very similar: off-the-shelf LKTR120 upgraded with micro-scisky setup.
