They are both based on our most reputable and best-selling board [STEMlab 125-14](https://redpitaya.com/stemlab-125-14/)and customized to even better fit your needs.  ![splosen-jpg](https://content.redpitaya.com/hs-fs/hubfs/splosen-jpg.jpeg?width=577&name=splosen-jpg.jpeg)   [STEMlab 125-14 Low Noise](https://redpitaya.com/product/stemlab-125-14-low-noise-starter-kit/) The new STEMlab 125-14 low noise is a STEMlab 125-14 board that is populated with additional linear analog power for analog power supplies to reduce RF inputs and outputs noise and consequently increase ENOB. To find out more about technical and mechanical specifications, schematics and the performance of the STEMlab 125-14 Low Noise read our extensive [documentation](https://redpitaya.readthedocs.io/en/latest/developerGuide/hardware/125-14_LN/top.html).  [STEMlab 125-14 Z7020](https://redpitaya.com/product/stemlab-125-14-z7020-low-noise-starter-kit/) STEMlab 125-14-Z7020 is a standard STEMlab 125-14 board that comes with Zynq 7020 (instead of Zynq 7010) that besides 3 times more FPGA logic provides also more digital IOs on the E2 connector (for more information refer to [board schematics](https://downloads.redpitaya.com/doc/User-DOC_STEMlab_125-14_V1.1%28STEMlab%20125-14%20Z7020%20LN%29.PDF)). It also has populated additional linear analog power for analog power supplies to reduce RF inputs and outputs noise and consequently increase ENOB. To find out more about the performance of STEMlab 125-14 with DC analog power supplies, refer to Leonhard Neuhaus’s blog [Red Pitaya DAC performance](https://ln1985blog.wordpress.com/2016/02/07/red-pitaya-dac-performance/).
