Strato Pi
Strato Pi is a professional expansion board that enhances the Raspberry Pi with several hardware features to make it suitable for use in professional applications where reliability and service continuity are key requirements.

Strato Pi complies with CE directives for EMC, Electrical Safety, Emission and RoHS.

Strato Pi has two versions: Base and UPS

Features:


 * 9-28Vdc power supply, with surge and reverse polarity protection
 * Real time clock (RTC) with on-board lithium back-up battery
 * Standard RS-232 and RS-485 interfaces to the Raspberry Pi serial line, with opto-isolator and electrostatic discharge protection
 * On-board buzzer, connected to an I/O pin of the Raspberry Pi board, for acoustic feedback
 * On-board LEDs for power supply and serial line activity
 * Power supply and serial connections on a screw terminal block

The UPS version adds:


 * Integrated uninterruptible power supply, with external lead-acid 12V battery
 * Simple UPS status and control via the I/O pins of the Raspberry Pi board
 * On-board LED for battery operations status
 * Hardware watchdog implemented in the Strato Pi board, fully independent from the Raspberry Pi, controlled via the I/O pins of the Raspberry Pi board

RPI1 Passive 1-Wire Module
The RPI1 is a very simple board to allow easy use of the kernel/GPIO based 1-Wire Master on your Raspberry Pi. It is available assembled or as a kit of parts.

RPI2 Single Channel I2C to 1-Wire Master
The RPI2 is a DS2482-100 based I2C to 1-Wire Master. Fully supported by OWFS it allows you to access the full range of 1-Wire devices on your Raspberry Pi.

RPI3 Eight Channel I2C to 1-Wire Master
The RPI3 is a DS2482-800 based eight channel I2C to 1-Wire Master. Fully supported by OWFS it allows you to access the full range of 1-Wire devices on your Raspberry Pi. Having 8 separate 1-Wire channels it allows you to build a large 1-Wire network. It also optionally features a DS1307 I2C Real Time Clock IC ensuring accurate timing for your 1-Wire data even after a reboot.

Guzunty Programmable I/O Expansion Board
The Guzunty adds open source programmable hardware to the Raspberry Pi at an amazingly low price. The design contains a 72 macrocell programmable logic device, so the board functions like a 'virtual breadboard'. This board is ideal for those with many different projects in mind, because it is so flexible. It can be a simple IO expander, a 7 segment LED driver, provide servo and regular PWM outputs, or anything you can dream up that will fit into 1600 logic gates. The device is '5 volt tolerant' and so can be used to safely interface 5v logic devices (such as Arduino) to the 3.3v Raspberry Pi. The GitHub community site contains many ready made cores that you can download and use directly. You can design your own custom cores using industry standard languages such as VHDL or Verilog.
