Red Pitaya STEMlab Starter Kits are designed using LTC2145-14 Analog-to-Digital Converter (ADC), AD9767 Digital-to-Analog Converter (DAC), and LTC3615 step-down DC/DC converter. These kits contain an SD card (16GB, class 10), 1m Ethernet cable, and a 5V, 2A power supply. The STEMlab starter kits feature Dual-Core Arm Cortex-A9 MPCore processor, Xilinx Zynq (7020, 7010, and 7020) FPGAs, and 512MB (4Gb) RAM. These kits offer 1Gbit Ethernet connectivity, USB 2.0, and WiFi connectivity using a WiFi dongle. The STEMlab 125-14 Z7020 Starter Kit comes with Xilinx Zynq 7020 SoC and can be used in a variety of research and space applications. The STEMlab 125-14 Low Noise Starter Kit is designed to reduce RF inputs and outputs noise and consequently increase ENOB. The STEMlab 125-14 External Clock Starter Kit is designed for RF applications that operate at other frequencies, require better quality clock or clock synchronization.
