All of the PI-REPEATER-X family of controllers are designed around the Raspberry Pi computer system. The PI-REPEATER-X controllers utilize the 40 pin GPIO expansion header on the Raspberry Pi< Zero/2/3> as the interface to the computer.  This leaves the USB ports, HDMI interface, etc all still available for your own expansion ideas.  Additionally, by using stackable headers (except the single channel unit, the PI-REPEATER-1X) the header pins that are left over, and the expansion buses like I2C and SPI<1> are still available for your own custom expansion projects.

The PI-REPEATER-X family accepts radio level signals for COS/CTCSS and provides a 2A rated MOSFET driven PTT signal so you can control either modern radios with digital 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, very useful for measuring things like temperature sensors, wind sensors, voltage sensors, whatever you need that provides an analog output can be fitted (custom code may be required to handle the data).

Since the PI-REPEATER-X family of controllers only uses the GPIO and standard logic buses (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 buses and GPIO pins.

We have chosen SVXlink as our operating controller software, so we know the most aboutthis platform, but certainly others will work with some configuration. For the audio, the Raspberry PI is known to have less than desirable audio, so included is an on-board stereo codec to keep the sound input and output sounding great.

GPS support has also been built into the PI-REPEATER-2X design so you can have a precise time source. We have chosen an off the shelf GPS 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 yet in available images.

Raspberry Pi Software

We encourage users of the PI-REPEATER Family to visit our friends over at OpenRepeater.com, who build a Raspberry Pi image preconfigured with a web interface that goes over SVXlink, that has built in support for our controllers with a quick setup option in the settings wizard.


Direct Radio Integrations

We have developed a few boards, and work will work on more as the requests and development time allows, that allow you to directly mate the PI-REPEATER directly to your radio without cables.  These are very compact solutions that are designed to mate directly to you radio where possible, utilizing the existing infrastructure for power, audio access, and etc where available.

Daniels/Codan MT3 Chassis

Currently there are 2 versions of the PI-REPEATER that will mate directly to your Daniels MT3 chassis.  We have the PI-REPEATER-1X-MT3 and the PI-REPEATER-2X-MT3, which offer single port integration and dual port integration respectively.  To learn more about these, hop over to the Daniels page, https://ics-ctrl.com/daniels-codan/.

Pi-Repeater-2x-MT3 installed











We are currently prototyping a design that mates to the MTR2000 natively.  This design is still in early prototyping, and will be available as soon as we can work out the details to get it all up and running and secure sourcing for the Raspberry Pi Zero computer boards. To learn more about these, hop over to the MTR2000 page, https://ics-ctrl.com/mtr2000/
