The SDRplay RSPduo is a high performance dual-tuner 14-bit SDR receiver. Housed in a high quality steel enclosure, each tuner can operate individually anywhere between 1 kHz and 2 GHz with up to 10 MHz of bandwidth or both tuners can operate simultaneously anywhere between 1 kHz and 2 GHz with up to 2 MHz of bandwidth per tuner.
A high stability reference along with external clocking features makes this device ideally suited to industrial, scientific & educational applications.

The SparkFun RP2350 Pro Micro provides a powerful development platform, built around the RP2350 microcontroller. This board uses the updated Pro Micro form factor. It includes a USB-C connector, Qwiic connector, WS2812B addressable RGB LED, Boot and Reset buttons, resettable PTC fuse, and PTH and castellated solder pads.
The RP2350 is a unique dual-core microcontroller with two ARM Cortex-M33 processors and two Hazard3 RISC-V processors, all running at up to 150 MHz! Now, this doesn't mean the RP2350 is a quad-core microcontroller. Instead, users can select which two processors to run on boot instead. You can run two processors of the same type or one of each. The RP2350 also features 520 kB SRAM in ten banks, a host of peripherals including two UARTs, two SPI and two I²C controllers, and a USB 1.1 controller for host and device support.
The Pro Micro also includes two expanded memory options: 16 MB of external Flash and 8 MB PSRAM connected to the RP2350's QSPI controller. The RP2350 Pro Micro works with C/C++ using the Pico SDK, MicroPython, and Arduino development environments.

What's with the silkscreen labels? They're all over the place. We decided to label the pins as they are assigned on the Apollo3 IC itself. This makes finding the pin with the function you desire a lot easier. Have a look at the full pin map from the Apollo3 datasheet. If you really need to test out the 4-bit SPI functionality of the Artemis, you're going to need to access pins 4, 22, 23, and 26. Need to try out the differential ADC port 1? Pins 14 and 15. The RedBoard Artemis ATP will allow you to flex the impressive capabilities of the Artemis module.
The RedBoard Artemis ATP has the improved power conditioning and USB to serial that we've refined over the years on our RedBoard line of products. A modern USB-C connector makes programming easy. A Qwiic connector makes I²C easy. The ATP is fully compatible with SparkFun's Arduino core and can be programmed easily under the Arduino IDE. We've exposed the JTAG connector for more advanced users who prefer to use the power and speed of professional tools. If you need a lot of a GPIO with a simple program, ready to go to the market module, the ATP is the fix you need. We've added a digital MEMS microphone for folks wanting to experiment with always-on voice commands with TensorFlow and machine learning. We've even added a convenient jumper to measure current consumption for low power testing.
With 1 MB flash and 384k RAM, you'll have plenty of room for your sketches. The Artemis module runs at 48 MHz with a 96 MHz turbo mode available and with Bluetooth to boot!

This kit includes iFixit's widest assortment of bits, complete with every driver head you’ll need to tackle any repair or DIY project. It includes standard bits like Phillips and Flathead in a full range of sizes to handle everything from precision electronics repair to home DIY projects. And it wouldn’t be an iFixit bit set if it didn’t include all the exotic bits from Pentalobes for Apple iPhone and MacBook repair to Gamebits for your vintage Nintendo consoles.
All of the next-gen bit sets have been re-designed in order to maximize convenience and usability. The bit set lid is held in place with magnets to increase product lifespan (no more broken hinges or clasps) and also mounts to the back of the bit set case to keep it out of the way while you do your work. If you need help keeping your screws and parts organized, you can use the lid’s integrated sorting tray. The 4 mm bits have been adjusted and have now a longer neck for a deeper and more precise reach.

Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.

This FeatherWing will make it easy to add data logging to any Feather Board you might have. You get both an I²C real-time clock (PCF8523) with 32 KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS).
Note: FeatherWing doesn't come with a microSD card.
A CR1220 coin cell is required to use the RTC battery-backup capabilities. If you're not using the RTC part of the FeatherWing, a battery is not required.
To talk to the microSD card socket Arduino's default SD library is recommended. Some light soldering is required to attach the headers onto the Wing.
Pinouts
Power pins
On the bottom row, the 3.3 V (second from left) and GND (fourth from left) pin are used to power the SD card and RTC (to take a load off the coin cell battery when main power is available)
RTC & I²C Pins
In the top right SDA (rightmost) and SCL (to the left of SDA) are used to talk to the RTC chip.
SCL - I²C clock pin to connect to your microcontroller's I2C clock line. This pin has a 10 kΩ pull-up resistor to 3.3 V
SDA - I²C data pin to connect to your microcontroller's I2C data line. This pin has a 10 kΩ pull-up resistor to 3.3 V
There's also a breakout for INT which is the output pin from the RTC. It can be used as an interrupt output or it could also be used to generate a square wave.
Note that this pin is an open drain - you must enable the internal pull-up on whatever digital pin it is connected to.
SD & SPI Pins
Starting from the left you've got
SPI Clock (SCK) - output from feather to wing
SPI Master Out Slave In (MOSI) - output from feather to wing
SPI Master In Slave Out (MISO) - input from wing to feather
These pins are in the same location on every Feather. They are used for communicating with the SD card. When the SD card is not inserted, these pins are completely free.

The Raspberry Pi A+ Case has been designed to fit both the Pi 3 Model A+ and the Pi 1 Model A+. The high-quality ABS construction consists of two parts. The base features cut-outs to allow access to the microSD Card and the the HDMI, audio/video and USB ports, as well as the power connector.
Plug a reader into the headers, use a Qwiic cable, scan your 125kHz ID tag, and the unique 32-bit ID will be shown on the screen. The unit comes with a read LED and buzzer, but don't worry, there is a jumper you can cut to disable the buzzer if you want. Utilizing SparkFun's handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins if you prefer to use a breadboard.
Utilizing the onboard ATtiny84A, the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card, attaches a timestamp to it, and puts it onto a stack that holds up to 20 unique RFID scans at a time. This information is easy to get at with some simple I²C commands.
Upgrade your Andonstar AD409, AD409 Pro, or AD409 Pro-ES to the Max model with this enhancement kit. The newly designed, oversized Max station provides ample workspace, making it perfect for larger projects and ideal for professional soldering tasks.

At the core of this module is ESP32-S2, an Xtensa 32-bit LX7 CPU that operates at up to 240 MHz. The chip has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring of peripherals. ESP32-S2 integrates a rich set of peripherals, ranging from SPI, I²S, UART, I²C, LED PWM, TWAITM, LCD, Camera interface, ADC, DAC, touch sensor, temperature sensor, as well as up to 43 GPIOs. It also includes a full-speed USB On-The-Go (OTG) interface to enable USB communication.
