STC Touch Button Demo Board EDA Version

STC Touch Button Demo Board EDA Version

This is a copy of the original design, with optimized layout and circuitry. It has been verified. It comes in a standard version and an extended Type-C version; the only difference is that the extended Type-C version has longer Type-C pads for easier soldering. I recommend using the extended Type-C version for prototyping. The test code is poorly written; I suggest replacing the U2 and SS8550 with MOSFETs like AO3401 during soldering.

Abstract
 

Robotic blimps, as lighter-than-air aerial systems, offer prolonged duration and enhanced safety in human-robot interactions due to their buoyant lift. However, robust flight against environmental airflow disturbances remains a significant challenge, limiting the broader application of these robots.
Drawing inspiration from the flight mechanics of birds and their ability to perch against natural wind, this article introduces RGBlimp-Q, a robotic gliding blimp equipped with a birdinspired continuum arm. This arm allows for flexible attitude adjustments through moving mass control to enhance disturbance resilience, while also enabling object capture by using claws to counteract environmental disturbances, similar to a bird. environments. To the best of the authors' knowledge, this is the first interdisciplinary design integrating continuum mechanisms onto robotic blimps. Experimental results from both indoor and outdoor settings validate the improved flight robustness against environmental disturbances offered by this novel design.
We have open-sourced the RGBlimp-Q hardware and code on GitHub.

TPS5430 outputs 12V

This is a power module that I personally find quite useful. It has a 36V input withstand voltage and outputs including 12V, 5V, and 3.3V. It also includes a reserved port for main control power supply. Feedback and discussion are welcome.

The main chips used are TPS5430 and AMS1117 (both versions 3.3 and 5) to implement a multi-purpose power supply module. Test holes are reserved in the lower part of the board. Soldering can be done as shown in the example diagram, with the terminals soldered to the back for improved aesthetics.

OpenMV4 - Four-layer board design

It has been verified to be usable and is an open-source OpenMV4 implementation I created for practice.

      This open-source project is based on the open-source four-layer OpenMV (OpenMV4-H7-four-layer-JALCIC EDA open-source hardware platform (oshwhub.com)) by author M., with a redesigned layout and routing. It uses Type-C and places all components on the surface layer (which can be soldered directly on a hot plate).
This is for personal DIY only; please do not use it for profit.
     The BOM is missing the main control chip, LEDs 1-6, the 24P-FPC socket, and several header pins. The chip can be either STM32H743VIT6 or STM32H750VBT6; the latter is much cheaper but has significantly less storage space. Both are usable. If the program is too large, it can be stored on an SD card. Purchase according to your needs. LEDs 5 and 6 are 1206-packaged 850nm infrared LEDs; the 24P FPC socket uses a flip-top, bottom-mounted 24P 0.5mm pitch design. (The camera stand is included with the purchase of the camera, but it's best to buy a few extra as spares.)
    This project uses an FPC 0.5mm pitch 24P ribbon cable camera, which supports 30W pixel OV7725 and 200W pixel OV2640 (I haven't tried the 50W pixel OV5640, so I don't know if it will work). The higher the pixel count, the lower the frame rate. I personally recommend the OV7725, which can run at 40+ frames per second. (Search FPC OV7725 on Taobao)
 
     Without further ado, here is a tutorial on burning firmware. There are many ways to burn firmware. Here is one of them:
1. Install and prepare the STM32CubeProgrammer software;
2. Use a TYPE-C cable and short-circuit RST and BOTO before powering on;
3. (1) Select the device connection interface (2) Select the USB connection mode (3) Search for the device (4) Click Connect Device;
4. (1) Select the firmware download interface (2) Select the directory path of the firmware to be downloaded (e.g., if openmvIDE is installed, you can find it in its installation directory D: openmvIDEshareqtcreatorfirmwareOPENMV4) (3) Click Download and wait for the download to complete;
5. After downloading the firmware, power off and then power on again. OpenMV will automatically perform a self-test. After the self-test passes, a virtual USB drive will be generated on your computer. At this time, you can test and run the program using OpenMVIED.
 
Finally, here is the flashing software:

///--------Update------------
2024-5-7: I found that the SD card could not be recognized after insertion. Now I have replaced it with another SD card slot, and the PCB has been tested and verified that the SD card can be recognized.
