In October last year, Digilent, an American company, launched the Arty Z7 development board, a new product aimed at makers and enthusiasts. This board is part of the Arty series, developed in collaboration with Xilinx to meet the growing demand for high-performance, scalable, and cost-effective FPGA development tools. The Arty Z7 continues the tradition of the Arty series—compact size, Arduino compatibility, and strong configuration. Earlier in the same series was the Arty A7, featuring the Xilinx Artix-7 FPGA. Recently, Digilent introduced new members to the Arty family, showcasing their enhanced features.
One of the latest additions is the Arty S7, based on the Xilinx Spartan-7 FPGA family. It comes in two versions: the Arty S7-25 priced at $89 and the Arty S7-50 at $109. The S7-50 version offers more resources compared to its predecessor. Below is a comparison of key specifications between the two boards:

Besides differing in FPGA chip size, both boards include 256MB DDR3L SDRAM, 128Mbit quad SPI flash, four Pmod ports, and an Arduino/chipKIT shield connector, maintaining the consistent design philosophy of the Arty series. The board also includes switches and LEDs, making it user-friendly for hobbyists.

The Arty S7 is the newest member of the Arty family, designed for makers and hobbyists. It leverages the latest Spartan-7 FPGAs, which offer greater flexibility in size and performance. These chips also incorporate Xilinx’s latest power-saving technology and are fully compatible with the Vivado Design Suite. This makes the Arty S7 highly versatile, offering numerous I/O options and expansion capabilities.
With two Arduino connectors, users can easily attach various shields or use Pmod ports to connect to existing Digilent IP blocks, enhancing the design experience. Additionally, the Arty S7 features a custom MicroBlaze processor, and developers can use the free Vivado Design Suite iebPack for development.

Overall, the Arty FPGA development boards from Digilent are thoughtfully designed to align with the habits and needs of developers. They offer a range of FPGA sizes to suit different resource requirements and integrate Arduino-compatible ports to lower the barrier for beginners. The support for Vivado and low-power development further expands their appeal. All these features are made possible by the advanced capabilities of the Spartan-7 FPGA. As Xilinx continues to innovate, we can expect even more powerful and useful development boards to emerge for the developer community.
Countdown Timer
FUNCTION DESCRIPTION
Countdown
socket has an AC outlet, the maximum can output 230 V16A of power,
there are two control modes, that is, countdown off and countdown on. It
is convenient to control the equipment which needs to switch off or
turn on AC. improve the safety of the use of some equipment and save
more energy.
SET Timer
1,Countdown
plug in the socket, all indicator lights red flash three times, at this
time the socket has no output, for the normal state, into the countdown
state. Click the button, the first red light up, the socket output
after an hour off, and then short press the button can set the socket
timing of 2 H.4H.6H.8H.10H.OFF.
2,Long
press button 3s, all indicator lights green flash three times, at this
time the socket has output, for the regular open state, into the
countdown on state. Click on the button, the first green light on, the
socket is closed an hour later, and then press the button to set the
socket countdown 2 H.4H.6H.8H.10H.OFF.
3,Press button 3 longer S, all indicator lights red light flash 3 times again into countdown mode.
4,Select
the required countdown time mode, the corresponding mode countdown
lights up, start countdown until the end of the countdown time. The
outlet that controls the output will start or stop the output.
5,After the countdown starts, the time indicator will change automatically from high to low until the countdown is over.
NOTE:
1,Check that the power connection is good.
2,Use only indoors and in dry places.
3,This product does not convert AC voltage.
4,Maximum load not exceeding 16A 3680W.
5,Grounding is required for safety.
6,Any questions, please contact the electrician.countdown timer socket, countdown timer plug, Countdown digital timer, Countdown socket, countdown switch socket
