Our latest creations are the PI-REPEATER-nX family of controllers. The tiny PI-REPEATER-1X is a full 1-channel repeater controller. The bigger brother and original PI-REPEATER-2X is a full 2-channel controller, and coming soon is the PI-REPEATER-6X modular system that supports from 1-6 full channels and an additional 2x TX only channel. All of the PI-REPEATER-nX family of controllers are designed around the Raspberry Pi computer system.
The PI-REPEATER-nX controllers utilizes the 40 pin GPIO expansion header on the PI Zero/2/3, using stack-able headers (except the 1X) so the pins that are left over are still available for your own custom expansion projects.
The PI-REPEATER-nX family accepts radio level signals for COS/CTCSS and provides a mosfet driven PTT signal so you can control either modern radios with logic level controls, or radios with relays that require more drive capability with ease.
In addition to interfacing with the radios, there is also a GPIO expander that provides an additional 8 digital logic pins. For analog sensors, there is also 8 channels of analog sensing things like temperature sensors, wind sensors, voltage sensors, whatever you need that provides an analog output can be fitted (custom code may be requried to handle the data).
Since the PI-REPEATER-nX family of controllers only uses the GPIO and standard logic busses (I2C, SPI, I2S), the hardware is compatible with any operating system you want to use, and any controller software that can interface with the logic busses and GPIO pins. We have chosen SVXlink as our operating controller software, so we know the most about this platform, but certainly others will work with some configuration. For the audio, the Raspberry PI is known to have less than desirable audio, so we include a stereo codec to keep the sound input and output sounding great.
GPS has also been partitioned into the PI-REPEATER-2X design so you can have a cheap network independent time source. We have chosen an off the shelf module from Spark-Fun that utilizes an SMA interfaced antenna, so you can have the freedom to put the antenna where-ever suits your installation. Note that the hardware supports the GPS, but software has not enabled this feature in our provided images.
We offer starter images below; these are being updated regularly, with added new features that are not all part of the standard svxlink packages. Documentation is being developed for these new features, but are briefly described for reference, these new variables are by individual port.

Standard config options (note this page is not maintained, so not comprehensive of new features)
In addition to the config variables, new expansion "modules" are available and being developed as listed below. See modules config files and tcl files for more details.
A2D_MXP320x - a new module that reads from a MCP320x A2D chip, easily customized to your specific sensors
REMOTE_RELAY - Control relays (GPIO) through the DTMF touchpad
SITE_STATUS - passive module that monitors sensors every second, includes digital and analog inputs
We understand that many of you already have a Raspberry Pi computer laying around, so we are offering a few options to get you only what you need to get going. You can add items directly from this page, or click into each item for more details as needed.
The PI-REPEATER-1X is a full duplex, single port repeater controller platform that mounts on your Raspberry Pi (Zero/2/3). In addition to supporting the interface for your repeater, 8x GPIO and 8x Analog inputs are available through 1x10 headers, which can be used to connect to sensors, alarms, etc. Note for Pi Zero users: While the hardware is compatible with the Zero boards, ICS starter images are not compatible with the Pi Zero Hardware. This is a result of incompatible arm versions in the processor CPU. SVXLINK can run on the zeros, but you will need to compile from source.)

Want to build up a PI-REPEATER but already have a interface cable that doesn't match our premade cables? This kit will get you there quickly, the kit comes with a DB9 shroud kit, a female DB9 solder cup connector, and a pre-crimped 2x5 ribbon cable. All you need to supply is the wire strippers, soldering iron and shrink tubing/epoxy as you desire for insulation of the solder joints.
This kit come with a DB9 male solder cup connector and the shroud body so you can build up the radio interface cables specific to your setup.

Ever wanted to interface your Raspberry Pi to something that only uses +5V logic levels? As you quickly came to learn, the GPIO on the Pi are not 5V tolerant, so hooking up the device to your Pi would render the board(s) damaged. This board takes care of the issue by providing level shifting circuitry for ALL of the GPIO pins, while still allowing you access to the 3.3V logic level signals as well. With this board, you can work with 3.3V GPIO and 5V GPIO together at the same time, even on the same pins at the same time. This is great for things like the SPI and I2C bus interface.
