用Xilinx的Artix-7 FPGA开发板,有DDR3 RAM、支持开发PCIe
关键特性

NiteFury Features * Giant FPGA: NiteFury features the largest Artix-series part that Xilinx makes. It has six times the processing power of PicoEVB. It uses the Xilinx A200T FPGA at just under 1000 GMAC/s. * On-board RAM: The faster you process with an Artix-7, the more you may need to store. The on-board DDR3, 512MB (256 Mb x 16) RAM keeps data within arms reach and takes the burden off your computer. * Popular Form Factor: NiteFury fits in the M.2 M key slot, which is popular in laptops today. This slot features 4x PCIe for high bandwidth (2 GB/s). Why keep your FPGA on your desk when you can take it with you? * Affordable: Buying the Xilinx Artix-7 XC7A200T FPGA alone would generally cost around $250. By teaming up with another company, NiteFury gives you all that power with little additional cost (especially during the campaign). * Open Source: Because company is good to have, NiteFury is open source hardware. The board repository is at https://github.com/RHSResearchLLC/NiteFury. * Expandable: With twelve external I/O in total, four of which are selectable as either analog or digital, you aren’t just confined to interfacing via computer. The connectors used in the design are easy to find Pico-EZmates and a DF52. Using NiteFury NiteFury is designed for seriously fast PCIe design prototyping. But essentially, it’s an FPGA (with RAM) inside your computer. So anything you can do with an FPGA, you can do quickly with NiteFury. Just design for your need in Vivado. Some fun things you could do: * Encode or decode large amounts of data lightning-quick on the hardware level * Encryption co-processing for securing your data in an efficient and accessible way * Sensor data pre-processing using the I/O Manage external hardware via I/O Specifications * FPGA: Xilinx Artix XC7A200T-2FBG484E * GMAC/s: ~1000 * Logic cells: 215,360 * Slices: 33,650 * CLB flip-flops: 269,200 * DSP slices: 740 * RAM: DDR3, 512MB (256 Mb x 16) * Form Factor: M.2 (NGFF) 2280, keyed for M slot * Dimensions (without heatsink): 22 x 80 x 5.5 mm * Dimensions (with heatsink): 22 x 80 x 10 mm * Host Interface: PCIe 4x gen 2 (2 Gb/s) * Host Tools: Vivado * External I/O: via I/O connectors - 12 total, 4 selectable analog or digital - JTAG ready * External I/O via PCIe connector: 1 x 3.3 V digital I/O (LED), SMBus * User-controllable LEDs: 4 NiteFury is open source hardware: https://github.com/RHSResearchLLC/NiteFury

24/7 Power for your remote projects makerPower Solar is a combination intelligent solar battery charger and power supply for low- to medium-power devices freeing them from the outlet. It is designed to provide 24/7 power for a wide range of embedded systems and IoT gadgets. Features & Specifications * 12 V Operation * Uses commonly available and inexpensive 25-35 W 12 V solar panels and 7-18 Ah sealed AGM lead-acid batteries (UPS batteries). * Lead-acid batteries are ideal for outdoor solar applications because they are lower cost that other battery technologies, operate over a wider temperature range and are safe. * 35 W Maximum Power-Point Charging * Implements a MPPT algorithm to operate the solar panel at the point of maximum power generation to extract every bit of energy the panel is capable of producing. More efficient that PWM-style chargers and much more efficient than just attaching the panel to the battery. * Three-state charger for fast and safe battery charging (BULK, ABSORPTION, FLOAT). * Charge Temperature Compensation * Temperature sensor monitors battery temperature and adjusts charge parameters to optimally charge the battery while protecting it from life-shortening overcharge conditions. * 10 W 5 V Power Supply * Available from USB Type A socket for plug&play with many devices or from a 0.1” header for direct connection. * Capable of powering a Linux SBC and long-distance radio like a cellular modem or SatComm module. * Low Battery Shutdown and Restart * Five-volt output disabled when the battery is almost discharged with automatic restart when the battery is recharged. * Alert signal available to provide warning of impending power-off for controlled shutdown. Use it to protect the filesystem in Raspberry Pi applications. * Digital Interface * I²C interface provides full access to charger measurements, state and configuration values. * Status signals allow direct control for simple systems. * Night-Only Mode * Automatically enable the system only at night. * Watchdog * Ensure system reliability by power cycling when the attached system crashes or hangs.
