Red Pitaya STEMlab 125-14 Low Noise Bare OEM SBC/FPGA Test-And-Measurement Board

Red Pitaya’s STEMlab 125-14 Low Noise Bare OEM board presents Red Pitaya’s low-cost, open-source platform without the connectors pre-attached, enabling its deployment in the most compact form factors with direct soldering for permanent, more robust installation – four SMA and two extension connectors are included should your project require them. As standard, this easy-to-integrate board measures at 14 x 10 x 4.5 cm.

In addition to increasing design flexibility, with users now able to use application-matched connectors and orientations over the default SMA I/Os, this connector-less version of Red Pitaya’s flagship board reduces mass, which is particularly useful for airborne and space applications.

As with other STEMlab 125-14 boards, the Low Noise Bare OEM board allows remote connection to a range of free, web-based measurement tools to support your application, without the requirement for installing proprietary software, though an internet connection is not required to use these tools offline once they have been deployed to the hardware. These tools include:

  • Oscilloscope & signal generator
  • Spectrum analyser
  • LCR meter
  • Bode analyser
  • Logic analyser
  • Vector network analyser

Users can also develop their own tools to support their desired use case.

The STEMlab 125-14 Low Noise Bare OEM board features 2-input, 2-output RF connectivity with both running 125 Msps at 14-bit resolution with a bandwidth from DC to 60 MHz. The full-scale input of the device is ±1 V and ±20 V at 1 MΩ. The device can output at ±1 V (50 Ω) with a slew rate of 2 V / 10 ns.

The Red Pitaya board can be controlled remotely over LAN (1 Gbit ethernet) or wireless networks (requires Wi-Fi dongle) using familiar research-level languages such as Python, MATLAB, and LabVIEW. The open-source nature of Red Pitaya also allows users to turn this pocket-sized multi-instrument device into a DSP development board, DAQ card, or FPGA development board, enabling its use in countless applications.

For those looking to program their own functionality, the STEMlab 125-14 boards also serve as a Linux single-board computer powered by a dual-core Arm Cortex-A9 processor supported by 512 MB RAM. System memory is provided through a micro-SD card with up to 32 GB storage, and Red Pitaya provides a lifetime license to Jupyter Notebook and a list of C code functions to enable users to access full control of the board. Free code is also available on Github for programming the on-board Xilinx Zynq 7020 FPGA.

Other interfaces include 16 digital I/Os, 4 analogue inputs (0-3.5 V, 12 bit), 4 analogue outputs (0-1.8 V, 12 bit), and other standard interfaces. These boards can also be daisy-chained over SATA connection (up to 500 Mbps) for more-demanding workloads.

If you’ve got a commercial project that requires on-the-go signal analysis, Red Pitaya has the solution, so fill out the form below, and ipXchange will get you connected. A range of application-specific variants of this board with the connectors in place are also available, including a 4-input version with a larger FPGA, so get a chat going, and Red Pitaya will direct you to their best board(s) for your project.
