“In all, there were ten different types of clouds: cumulus, stratos, cumulonimbus, stratocumulus, nimbostratus, altocumulus, altostratus, cirrocumulus, cirrostratus, and cirrus – each with their own personality: fluffy, detached, transparent, thin, continuous, gray, heavy, dense, semi-transparent, and layered, which I use to describe my own moods and feelings at any given time.” ― Sia Figiel
Can you believe CircuitPython is now in its sixth iteration? That’s right! Join us and Blinka as we soar higher and higher into the big, electronic sky of coding future.
Feature-wise, this stable latest release adds basic lower power support when in time.sleep() and initial ESP32-S2 support. The ESP32-S2 has native wireless WiFi support, which lets Blinka soar higher and higher!
Instead of being a single embedded functional module, Wio Terminal is more of a complete system equipped with Screen + Development Board + Input/Output Interface + Enclosure. Because it uses the SAMD51, it is compatible with Arduino and CircuitPython – using the same Arduino & CircuitPython core we have developed here at Adafruit!
Wio Terminal is an ATSAMD51-based microcontroller with wireless connectivity supported by Realtek RTL8720DN. Its CPU speed runs at 120MHz (boost up to 200MHz). Realtek RTL8720DN chip supports both Bluetooth and Wi-Fi providing the backbone for IoT projects. The Wio Terminal itself is equipped with a 2.4” LCD Screen, onboard accelerometer (LIS3DHTR), microphone, buzzer, microSD card slot, light sensor, and infrared emitter (IR 940nm). On top of that, it also has two x JST PH 4-pin STEMMA / Grove ports for Grove Ecosystem and 40-pin compatible GPIO for more Raspberry Pi add-ons.
Right Mecanum Wheel – 48mm Diameter – TT Motor or Cross Axle
If you’re unfamiliar with mecanum wheels, this 48mm Diameter Mecanum Wheel may resemble an everyday chunky wheel Frankenstein’d out of mini hair curler rollers. In reality, it’s a very cool, omnidirectional wheel with rollers which are supported by ball-bearings, allowing a four-wheeled robot rober to move in any direction. There are nine rubber beads around the perimeter of the wheel that lets it grip the floor when moving sideways.
Left Mecanum Wheel – 48mm Diameter – TT Motor or Cross Axle
These wheels have a little insert that lets them be used by LEGO-compatible cross-bar or low cost TT motors. They simply snap on.
This is the LEFT wheel, you can tell because there’s an L embossed on the hub. You will need at least 2 left and 2 right wheels in order to use all of the movement combinations.
ESP-PSRAM64H Chip – 64 Mbit Serial Pseudo SRAM – 3.3V 133 MHz
The ESP-PSRAM64H is a 64 Mbit (8 Megabyte) serial pseudo SRAM device, organized in 8 M x 8 bits and in a compact SOIC-8 package. It is fabricated using the high-performance and high-reliability CMOS technology and can operates at 3.3V and can support up to 133 MHz clock rate. Note, however, that burst operations which cross page boundaries have a lower max input clock frequency at 84 MHz.
The PSRAM device can be accessed via basic Serial Peripheral Interface (SPI) or faster Quad Peripheral Interface (QPI) is supported if the application needs faster data rates. Because it is RAM not FLASH or EEPROM, this device supports unlimited reads and writes to the memory array.
Clear Acrylic Enclosure + Hardware Kit for Adafruit CLUE
Here is a chic minimalist enclosure for your CLUE board! This case has been laser-cut specifically to accommodate the TFT display, tactile buttons, and capacitive pads.
And of course, we include mounting hardware so you can assemble it right onto your CLUE board. Takes less than five minutes to assemble, just find a nearby screwdriver.
Please note: It won’t work with the BBC micro:bit, only the Adafruit CLUE.
HDMI Input to USB 2.0 Video Capture Adapter
Here’s one of the easiest capture solutions for getting HDMI data into your computer or Raspberry Pi, really any system with a USB port..
Use this capture device to convert a video signal from a camera (or another device) into a digital format your computer can recognize. Its trivially easy to use: connect one end to an HDMI output up to 1080p. Connect the other end to a mainboard USB port.
This dongle doesn’t have the quality of $100 or $1000 converters, but for every day HDMI capture it works very well for the price! No drivers to install. Plug and play with Windows, Mac, Linux – shows up like a video source and a great option for streaming data from game consoles.
Adult PM2.5 Filtering Face Mask With 4 Filter Inserts – Black
This snazzy and smart Adult PM 2.5 Filtering Mask in Black looks great while keeping you covered! The outer layer is made of a tightly woven cotton that holds its shape. The inner layer is made of a soft brushed cotton layer. The inner layer has an overlapping slot that you can slip a PM 2.5 filter insert into. The mask comes with four (yes four!) filter pieces.
Adafruit TDK InvenSense ICM-20948 9-DoF IMU (MPU-9250 Upgrade) – STEMMA QT / Qwiic
When you want to sense orientation using inertial measurements, you need an Inertial Measurement Unit, and when it comes to IMUs, the more DoFs, the better! The ICM20948 from Invensense packs 9 Degrees of freedom into a teeny package, making it a one stop shop for all the DOFs you need! Within it’s svelte 3x3mm package there are not just one MEMS sensor die like your common sensors, but two sensor dies! The ICM20948 pair’s Invensense’s MEMS 3-axis accelerometer and gyro with the AK09916 3-axis magnetometer from Asahi Kasei Microdevices Corporation.
Strain Gauge Load Cell – 4 Wires – 20Kg
A strain gauge is a type of electronic sensor used to measure force or strain (big surprise there). They are made of an insulating flexible backing with a metallic foil pattern. The resistance of a strain gauge changes when force is applied and the object is deformed along with the foil and this change will give a different electrical output. However, these thin foils are very delicate and are easy to over-bend.
In this product, the gauge is attached with epoxy to a chunk of strong aluminum. The metal keeps the strain gauge from being damaged, and constrains the amount of movement. Attach one side to a fixed enclosure or ground, using the mounting holes, to keep them from moving. Then apply weight to the other side in the direction indicated on the side, either by gravity (so arrow pointing down) or by pulling (arrow facing up). The output resistance will change with the amount of deflection, and is measured with a precision ADC or Wheatstone bridge.
Monochrome 0.96″ 128×64 OLED Graphic Display – STEMMA QT
These displays are small, only about 1″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
This breakout can be used with either an SPI or I2C interface – selectable by cutting two jumpers on the back. The design is completely 5V-ready, with an onboard regulator and built in boost converter. It’s easier than ever to connect directly to your 3V or 5V microcontroller without needing any kind of level shifter!
Adafruit ST25DV16K I2C RFID EEPROM Breakout – STEMMA QT / Qwiic
This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C. The tag shows up as an ISO/IEC 15693 (13.56MHz) chip which is readable by phones and tablets. This could be interesting in situations where you want a tag that can be re-written dynamically when connected to a controller. For example, we did a test where we had a microcontroller write different URLs a few seconds apart, and the mobile phone detected the different URLs one after the other.
