Prototype Expansion Board

[Jen Ondrey]

Thats called a "prototype shield" It really doesn't do much. It's essentially just a way to mount a solderless breadboard (the white plastic thing) on top of your Arduino. Solderless breadboards make it very easy to prototype circuits by poking leaded components, modules, and jumper wires into the holes in the breadboard. Inside the breadboard are spring contacts that connect all the holes on each row on one side or the other of the breadboard together. There is a break down the center of the breadboard so the contacts on either side are not connected. There is also a small section of the prototype shield where you can solder components to form a permanent circuit. There is a SOT footprint for soldering a surface mount IC.

In spite of the markings on the board, I kept mixing the 5V and Gnd on those 5 hole headers, so I stuck some red (for +ve) insulation tape on and near the 5V ones so I can tell at a glance.

This shield is used to build prototype circuits can be directly soldered components on the board, you can also connect the circuit through the above mini breadboard. Between breadboard and the board through the double-sided adhesive connection, when sold breadboard and the board are separate.

The UNO Proto Shield prototype expansion board with SYB-170 mini breadboard makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard to quickly test circuit ideas without having to solder.

The schematics have been finished kinda, The PCB has been made (see photos below), and the chassis has been 3D printed. Just note that this is an early prototype version of a scroll wheel expansion card (roPlug V0.0.1a), and requires a USB-C to USB-A adapter to work. Update: fixed the circuitry and now works without problems!

Depending on your operating system, take a dive through this wonderfully written instruction on setting up QMK on your computer. The link should get you setup and ready to run QMK on roPlug; however, I recommend reading through other sections to get familiar with QMK.

Once roPlug is in bootloader mode, it will then wait for QMK to load and flash the custom key map created in the configuration. Once QMK finishes flashing roPlug, you can place the board back into the chassis, and start using it like a champ!

why do you need the usb A adapter? does it physically fit?

i noticed on the schematic you have two 22 ohm resistors on CC and VCONN- this is wrong, you should have one 5.1k resistor on CC. might explain it

One way I think you could do a quadrature encoder in a really thin space would be kind of like this thing from polulu- sot-23 hall sensors (they detect magnets) on one side of the pcb, 90 degrees apart, and a magnet wheel on the other side. The resolution depends on the number of magnets in the wheel, as shown by this guy quite nicely.

The Keyestudio Pico IO prototype expansion board works with the Raspberry pico board. It can expand IO ports of the pico board. There are two IIC ports, a serial communication interface , three analog ports and six digital ports.This sensor board simplifies the circuit and makes it easy to connect with commonly used sensors. You can stack a Raspberry Pi pico board onto this shield.

Add a prototyping area to your Crazyflie 2.X and lift your electronicsinto the air. Just solder directly on the expansion deck and plug itinto the expansion port. Maybe try to add a few LEDs or a new sensor to detectproperties of the world around the Crazyflie?

If you want your prototype deck to be detected automatically by the Crazyflie, for example to activate your driver code when the deck is connected, you can solder a one-wire memory DS28E05 in the pads near P1 pin 10.

The X-CUBE-MATTER expansion package provides software components running on different STM32 microcontrollers development platforms based on Arm cores. A development platform consists of a set of hardware: a single board or a combination of two boards. The choice of the platform mainly depends on the target transport technology (Thread, Ethernet, Wi-Fi) and the target type of Matter device (Matter end device, Matter bridge). Binaries are provided for a quick demo.

The STM32 SoC embeds most of the hardware blocks (Flash, crypto engine, RNG, RTC). The different connectivity technologies can be embedded in a standalone SoC or a chipset. Thread, Bluetooth Low Energy, Wi-Fi, and Ethernet technologies are supported along with STM32 microcontroller families. The supported technologies are detailed in this wiki.

The project stores the device credentials and keys in the STM32 embedded flash memory or an external flash memory for which X-CUBE-MATTER provides a driver. The project offers infrastructure from partners for provisioning DAC private key into STM32 secure storage (CKS). It also provides a related driver for operational network. Once provisioned, the security-sensitive data and operations remain in a secure partition, where they are not exposed to the user application. The secure boot process acts as a Root of Trust for the application before launching it. It takes care of the secure firmware update once a new image has been downloaded by the user application.

OpenThread stack, Bluetooth Low Energy stack, and IP stack can be located on the application MCU in the case of chipset solution or on the dedicated wireless stack coprocessor. The software partitioning for each target platform is detailed in this wiki.

The delivered application examples as part of the project are provided with compiled binary for an out-of-the-box experience. Source codes are also provided and can be compiled with supported IDEs. Finally, the project can be modified and regenerated using STM32CubeIDE. For features supported with this version of X-CUBE-MATTER (Matter SDK version, supported applications and their list of features), refer to the release note.

The Drivers folder contains the HAL drivers, the board-specific drivers for each supported board or hardware platform (including the onboard components), and the CMSIS vendor-independent hardware abstraction layer. These are STM32Cube firmware components.

The .zip file in the APK subfolder contains the CHIPTool application used as commissioner and controller in STM or RPi ecosystems. This CHIPTool has been generated using source code from CSA GitHub. It is provided for convenience. Be aware that it does not run on every Android platform as it has been built for Arm54 CPU based devices and Android 8 or later is required.

The OTA_Tools subfolder contains scripts provided with X-CUBE-MATTER for OTA firmware update over Matter. The subfolder chip within OTA_Tools contains functions coming from connectedhomeip\src\controller\python\chip\tlv and used by these scripts.
