PI REPEATER 2X

Our latest creation is the PI-REPEATER-2X, a full 2 channel repeater controller designed around the Raspberry Pi computer system. The PI-REPEATER-2X utilizes the 40 pin GPIO expansion header on the PI 2/3, using stackable headers so the pins that are left over are still available for your own custom expansion projects.

The PI-REPEATER-2X 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-2X 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 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.

BUYING OPTIONS

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.

PI-REPEATER-2X Controller Only

PI-REPEATER-2X

The PI-REPEATER-2X is a full duplex, 2 port repeater controller platform that mounts on your Raspberry Pi 2/3. INCLUDED: 1x 2-port controller board, 3x DB9 interface cables (2 ports and ADC), 1x DB15 interface cable (GPIO interface) REQUIRED ACCESSORIES: 1x Raspberry Pi 2/3 computer, 1x Ethernet Cable, 1x 2.5+A MicroUSB power source, 2X Cables to interface your radios OPTIONAL ACCESSORIES: 1x Enclosure (recommend metal, fully enclosed), 1x Sparkfun GPS module (See manual), 1x Sparkfun GPS antenna (See manual) IMPORTANT NOTE: During initial launch we are expecting a meaningful number of orders, but like with all things we have to balance inventory on hand vs predicted sales volume. To further complicate things, we are offering multiple kits that will all consume the controllers and accessories in varying quantities. To allow for this, we are going to allow the inventory to go negative and will order additional runs as we see the sales warrant. This may result in some back-orders, but rest assured we will be actively monitoring the situation to minimize the lead-times. Manuals are being developed so these are still incomplete, but feel free to browse what is provided so far to get a sense of the features of the platform

GPIO VOLTAGE LEVEL SHIFTER

Raspberry

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.
