This is a very basic PCB to put a Raspberry Pi Zero into an old sinclair spectrum 48k case...
Code is by a Mr P J Evans and is called ZX Scanner on Github, I've basically made a PCB of his work and added my own hardware parts!
There's a footprint for an RTC this will use generic Pi RTC code
There's a footprint for an Adafruit I2S amplifier board...i've only put this in for those that want to run...
The second version of the Cross-board for Raspberry Pi B +, 2, 3. The first version is located at [this] address
1. 8 digital inputs with opto-coupler;
2. 8 outputs with solid-state relays;
3. Communication interface RS485;
4. Real-time clock;
5. Conclusions of 1-Ware interfaces (with 3.3 volt power supply), I2C (with 3.3 and 5 volt power supply and matched levels);
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:
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]
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
- Add a way to redirect Ethernet d...
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.
This PCB is designed to drive five strips with WS2812B LEDs (or their variants) along with a Raspberry Pi (any version) from a single ATX power supply unit.
The five 5V ATX power rails are distributed to the five LED strips. While the data is forwarded between the strips.
The data path starts at the Raspberry Pi, which is connected to the first LED strip. From the end of the firs...
