PoE (Power over Ethernet) to USB 5V adapter.
Current use cases:
- Power micro controllers (Arduino's or Pbpi's)
PoE Switch --> **PoE to USB** --power--> Rbpi
Switch ------------Data----------------> Rbpi (There is still a second Ethernet cable needed for data over cable.)
- Charge your Phone or other USB devices
- Trying to support 802.3af

Inspired by N-O-D-E's (Not to be confused with the gaming channel) [Nano Server V2 PCB Bridge](https://n-o-d-e.net/nano_server2.html), my variant is designed to fit on Apple's 5W US Charger and now for the US IKEA Koppla USB charger with a 3D printed enclosure. The reason I designed this PCB is that Node's PCB only fits a specific charging adapter and a specific USB Type A Male plug that I believe...
A board to break out Raspberry PI GPIO into db9 Sega ports and gamecon supported devices
Gamecon and db9 driver rules apply. There's no magic here, just a simple breakout board.
The I2C port is only usable when using just the DB9 ports.
Circuit to drive the DHT22 temperature and humidity sensor via the SPI bus.
The advantage is, that it uses next to no CPU resources as everything runs in hardware on most platforms.
This allows a multitaking OS like Linux to reliably read the sensor without issues.
Interface a Raspberry Pi 3.5 inch TFT LCD to an STM32F103C8T6(blue pill). This LCD with resistive touch screen uses SPI to connect to the STM32. Can also be used to connect to Arduino Pro Mini by adjusting relevant SPI pins.
This is a shield prototype for a rover started in the University of Northern Colorado's Department of Physics and Astronomy for the Colorado Space Grant and Consortium's robotics competition. This shield serves as beginning platform for future student to build upon.
Any comments, suggestions, or anything else please contact the main designer: Brandon Williams -- [email protected]
This prototype board expands the GPIO pins of the Raspberry Pi to headers numbered like the software (Wiring Pi) uses this. Made for Educational purposes.
Great advantage is that students make less mistakes in the electronic circuit. When they do make a mistake, debugging is much easyer.
You can also use the prototype board in examples of Fritzing:
Level Shifter to run 5V NeoPixels (WS1812B) LEDs via a 3.3V SPI bus (e.g. Raspberry Pi).
The P-SPI header was designed in such a way, that the PCB can be plugged on top of the Raspberry without further cabeling.
The P-LED-DRIVE outputs the signal to the LEDs, while P-LED-SENSE _optionally_ connects to the output of the last LED in the chain.
Connecting P-LED-SENSE allows a software running on the...
Touch sensor using AT42QT1010 with power led indication.
For power led indication, use in conjunction with Delay Timer connected to GPIO14 (https://easyeda.com/lynxlabeling/delaytimer).
Note: this circuit is connected to an N-channel Fet, which pulls GPIO3 pin low when activated. Add 'dtoverlay=gpio-shutdown' to /boot/config.txt file to use. For info, see:
