Description。This 4-pin， ATX， right angle connector mates up to the standard 4-pin computer peripheral port often found on ATX power supplies. This connector will also serve as a replacement to that found in the SparkFun ATX Power Connector Breakout Kit.。Features。Works with 12V 5V devices.

Description。This is the Antenna Kit for the Raspberry Pi 4 Compute Module wireless variants. The "duck" style antenna adds range to the wireless radio on the wireless enabled Compute Modules. Something quite desirable if you're working in industrial environments or other places a Compute Module would be used and the potential for signal interference is present. The antenna connects to the board via the press-fit U.FL connector on board the compute module(see photos for more details).。This kit contains an antenna， bulkhead fixture， and SMA to U.FL Cable.。Features。Frequency range：2400-2500/5100-5800 MHz。Bandwidth：100-700MHz。VSWR：≦ 2.0。Gain：2 dBi。Impedance：50 ohm。Polarisation：Vertical。Radiation：Omnidirectional。Maximum power：10W。Antenna dimensions：108 mm×10 mm

5V/3.3V breadboard power supply designed by SeeedStudio. It can directly takes power from DC wall wart and outputs both 5V and 3.3V regulated voltage. Compare to other breadboard power supply designs、this one provided micro-USB port、you can use both 5V and 3.3V regulated voltage. The 5V/3.3V breadboard power supply includes micro-USB port and power jack port. This power supply fits the breadboard which is 5.3cm wide like Bread board Clear - 8.2×5.3cm、and it can fit the 5.5cm wide breadboard too Basic Bread board - 16.55.5 cm、but just a little tight.。Features：Dual lane outpu。Dual power port input。5V/3.3V regulated voltage。Maximun output current is 400mA。Part list：5V/3.3V Breadboard Power Supply Board 1。Specification：Input voltage：7V 15V。Output Voltage：3.3V Channel：3.267V - 3.333V。5V Channel：4.9V 5.1V。Output current 400mA

。SDLogger is a simple serial logger based on SparkFun/Nathan Seidle's OpenLog. It is using an ATmega644P processor running at 14.7456MHz and logs to full-size SD cards. It supports both standard SD cards(FAT16)and SDHC cards(FAT32). SDLogger ships with OpenLog firmware 1.61 installed(compiled with SDHC/FAT32 support and large 2048 character input buffer)together with an Arduino-compatible bootloader for easy program update.。Features。Simple to configure and use。Automatically logs data received on the serial input port。Can be configured using a config file on the SD card。Supports 2400、4800、9600、19200、38400、57600、115200 and 230400 serial baud rates at 8-N-1.。Supports both standard SD cards up to 2GB(FAT16)and SDHC cards up to 16GB(FAT32)。Large input buffer(2048 characters)。Full-size SD card form factor。14.7456 MHz crystal oscillator for precise baud rate generation。Input voltage range：3.3 to 12V。Arduino-compatible bootloader installed for easy program update。Full Arduino environment support - can be used as an inexpensive Arduino board for program development。I/O ports supported in Arduino environment(in addition to the main serial port)：4 analog inputs、second serial port、I2C port。Simple SDLogger original firmware restore procedure using the Arduino environment。SDLogger hardware/firmware designed by Saanlima/Magnus Karlsson and released under CC BY-SA v3 license。Design files、Arduino code and other ported code available on GitHub

Description。Jump-start your IoT development with the Omega2+ Starter Kit. This kit includes everything you need to create eight different circuits that will teach you how to control LEDs， read inputs， control and read external sensors and displays， learn Python， and more. Step-by-step instructions for building each circuit with the included parts can be found in the online Starter Kit Guide under the "Documents" tab.。Each Starter Kit includes an Onion Omega2+ IoT Computer， an Expansion Dock and a variety of electronics components that belong in the collection of every student of Internet of Things. This collection includes resistors， LEDs， jumper wires， switches， a 7-segment display and an LCD screen， to name a few. All kit components are nicely packed up in a handy plastic carrying case.。The Onion Omega parts we carry are separated into three different categories：Mainboard， Dock and Expansion Board. With the parts in this kit you will be able to plug the Omega2+ into the Expansion Dock and add any Expansion Board! For a kit that includes all of the parts in the Starter Kit plus the Expansion Boards， check out the Omega2+ Maker Kit.。Examples。Blinking an LED --- Learn the basics of programming the Omega by turning an LED on and off.。Blinking Multiple LEDs --- Learn some more programming concepts by controlling multiple LEDs at once.。Fading an LED --- Create a cool LED fading effect using the Pulse Width Modulation(PWM)technique.。Reading a Switch --- Use a physical switch to control an LED through the Omega.。Using a Shift Register --- Use a shift register chip to control eight LEDs using only a few GPIOs.。Controlling a 7-Segment Display --- Add a 7-segment display to the previous circuit to display numbers.。Reading a 1-Wire Temperature Sensor --- Use a 1-wire temperature sensor to read the ambient temperature.。Controlling an LCD Screen --- Use the I2C protocol to control an LCD screen attached to the previous circuit.
