The installation size is 30*30MM two-way brushless ESC, single-panel layout, convenient for DIY welding of small-sized and high-power brushless ESC for model aircraft
based on CW32 microcontroller .
4-way brushless motor drive can be realized through superposition. Standard hole position, can be installed on drones such as traversing machines and large four-axis drones
. It supports PWM. The D600 digital protocol will be expanded later, and the forward and reverse rotation can be adjusted for fast response. Connect a copper strip to the bottom to expand the current. The target is 20A single channel and strive for 30A, actual picture. Currently, the flashing light program can be run when connected to power. The motor code is still being modified and debugged.

This is modified based on the F411 fixed-wing flight control of the foggy guy.
The layout has been modified according to my habits
and has been tested as follows: 1. Normal flashing of firmware 2. Ground station identification. Serial ports 1 and 2 are normal. Receiver ELRS identification, GPS identification, barometer identification, 3. OSD normal display. Image transmission is normal 4. 1-6 pwm is normal, ESC and servo are working normally 5. Attitude is normal, no jitter
Supported but not tested function 1. ppm, sbus receiver 2. External compass 3. External galvanometer 4. Figure
Suggestions for making parameter-tuning soft serial ports:
Some friends may encounter difficulties in entering DFU mode. Can't flash firmware. The method of flashing the firmware is the same as that of the F405 flight controller, just search on Station B.
1. Check the welding to see if there are open circuits in 5V and 3.3v, and whether the 5v 3.3v voltage is normal
. 2. If you really cannot flash the firmware, it may be because the USB power supply is insufficient. You can solder the BEC that comes with the flight controller, and then press and hold the boot button on the flight controller. Finally, use battery power to enter dfu mode and connect to the computer to flash the firmware.
The flight control has been successfully tested. The board schematic diagram is drawn according to the domestic manufacturer's definition file.
Please note that there are some minor errors in the labeling of some sensor interfaces. The definition is correct, which is the difference between MOSI 1 and MOSI -1. It is recommended to build the board directly. You have to do it yourself. Check the schematic.
Functions that have been tested 1. No jitter during normal takeoff. The S1234 channel outputs normally and the orientation is normal. The gyroscope is stable and does not jitter. 2. OSD displays normally, camera and image transmission are normal 3. Voltage detection is normal 4. Serial ports 1, 4, 5 are used normally, connected to GPS, receiver is used normally 5. BB ring is enabled normally 6. LED light is normal 7. Compass, The barometer is recognized normally. IC2 interface is available.
8. BEC 5V is normal
. 9. Automatic return test is normal.
10. TX 4 serial port uses OSD parameter adjustment to
test normally. NG project
TX2 cannot be used when connected to OSD parameter adjustment
. The newly added 20-hole mini flight control cannot be used. Many group members have already made it successfully, so feel free to make it. If it is not recognized or successful, it must be a problem with your welding or chip.
After the hardware welding is completed, press and hold the BOOT button and use the USB cable to connect the bf and INAV ground stations. After entering the DFU mode, install the driver, and then click Burn Firmware. You do not need
downloaders such as STLINK or serial cables, just use the USB cable.
If you don’t understand, you can refer to the tutorial on Baidu to flash the F4 flight controller firmware
. This is purely a personal DIY communication. Please do not use it for commercial purposes. There are many imitations and references of open source solutions. If there is any infringement, please contact me to delete it. Thank you! !

【Collection】Happy little duck
Introduction: Based on Yuxin's YX-2.4G single-chip transceiver and bidirectional IO monitoring and frequency communication, it cooperates with 1818AM to realize 4-channel motor forward and reverse drive
The 4-channel remote control produced this time is simple to make, has the right level of difficulty, has a high success rate, and does not even require debugging. It can be completed very quickly and efficiently in some basic productions! Make your own model move! It is also
very happy to be able to personally experience the charm of wireless remote control and enrich your life during the summer vacation ! (๑><๑) Delicious!
Thank you Jialichuang EDA@Jialichuang!
Convenient and efficient board-making service support! Provide us with excellent circuit boards!
All merchants or stores that appear are not advertised! No advertising! No advertising! No advertising!
The first-person and third-person test videos of Duck@Car are in the attachment!
This time, a domestically produced 2.4G+MCU packaged chip is used. It is an integrated chip produced by Yuxin Microelectronics. It codes an 8-function remote control car IC and controls the forward and reverse rotation of 4 sets of motors at the same time.
Also used with 1818AM, each one has two H-bridges integrated inside, which can directly drive two DC motors. The average output current of 1.8 A is enough to satisfy this application scenario.
The main features are
low power consumption, convenient design, and saving hardware costs. The bottom layer of the chip has its own communication protocol, and the onboard micro-antenna can be used. As long as simple peripheral circuits are used, it can work normally.
This modification is very convenient.
A charge and discharge management TP4056 is added to the launch board, which saves you the trouble of finding a battery.
A small 200 mAh battery, thanks to its low power consumption, can also be played for an entire afternoon, but it still has a launch distance of 50 meters.
Note that
on the launch board, I merged the two channels into one group for forward and reverse, which can spread some power and reduce the heat of 1818AM. When
receiving
the second version of the board, the soldering pads were replaced with spring-type terminals, which made wiring more convenient and operation smoother!
The standard length of the antenna is 34mm!
The design logic
draws power from USB → boosts the charge to the battery through XL6019. Because it is a non-standard charging voltage, no special charging and discharging power management chip is used.
The recommended maximum charging voltage is 7.5V, and the maximum withstand voltage of 1818AM is 8V.
Welding recommendations for
C4 and C6 chip capacitors are best to put some solder paste on the pads, align them, and use a soldering iron to solder them.
Battery→Power distribution LDO chips
are AMS1117 and 78M05 respectively, which respectively supply the receiving power supply and the +3.3v required by 1818AM, and a set of 5V output power supply, which simultaneously supply power to the relay and also serve as an output to power the TF card player.
The water is clear and the bottom is crystal clear.
The positive VCC output power of the battery is set to 1818AM. Since the motor works underwater, it has greater power and can be provided with an appropriate heat sink. When the power voltage is ≥6v, a heat sink should also be provided.
In the binding method,
first turn on the power supply of the receiving board and then the transmitting board. When the frequency binding is successful, the receiving board indicator light is always off and the transmitting board indicator light is always on. There is a teaching video attached!
Notes on modification:
In order to save costs, a miniature water pump was used to modify the submersible motor with moderate power. Buy a horizontal type with 2 pairs of front and back blades.
Modify the motor and install it like this. It is recommended to use AB or hot melt glue when bonding, and 704 silicone rubber for waterproofing.
The three channels are used to control the entire duck, forward, backward, (turn left, turn right, use one channel)
, and the two-layer grip is more comfortable.
This channel of SW is used here to control the pause and start of the player.
For example, you can use it to light firecrackers wirelessly during the New Year, haha~
There is a first-person perspective video in the attachment.
At this point, our little duck has been modified. Let’s quickly call our friends to modify one! Come on
remote control car
! (๑><๑) Yummy!
