TinyPICO – ESP32 Development Board – V2: The smallest, most feature-rich ESP32 dev board is here! TinyPICO has incredible processing power for a board that’s shorter than an alkaline battery.
Thanks to creator-maker Seon Rozenblum, you can tinker with a tiny, mighty, uncompromising board with 4MB extra RAM, on-board RGB LED, and a 700 mAh 3.3V regulator. MicroPython firmware is pre-loaded, and with support for Arduino IDE and Espressif IDF, you get the flexibility to code your way.
INA219 High Side DC Current Sensor Breakout – 26V ±3.2A Max – STEMMA QT: This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision.
Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter – it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels.
Pimoroni Mood Light – Pi Zero WH Project Kit – V2: Our Pimoroni pals have curated a beautifully modern Mood Light Kit that’ll look great on your bedside table, bookcase, or desk. It’s even internet-connected!
This kit has just-about-everything you’ll need: Pimoroni’s Unicorn pHAT board with 119 programmable RGB Neopixel LEDs, diffuser, power adapter, and a beautifully acrylic enclosure to make it look like a lamps. It even includes a Pi Zero WH. All you need is to add your own micro-SD card and USB power supply. It’ll take you around 30 minutes to assemble everything (check out Pimoroni’s assembly guide for details). With this new version, no soldering is required!
Set it to a single color, have it fade through all the colors of the rainbow, or harness the built-in wireless LAN on the Pi Zero WH.
Submersible 3V DC Water Pump with 1 Meter Wire – Horizontal Type: Make fountains or plant-watering projects with this submersible water pump. It’s great for beginner projects and super easy to use! The pump is basically a DC motor that is powered with 3V and draws 100mA. When powered, the pump sucks water in from the side of the plastic casing and pushes it out the tubing port. The pump must be primed by keeping it inside water at all times. Reversing the polarity does not turn it into a suction device, it will only pump water!
This isn’t for use with drinking water! We don’t have longevity rating for this pump, we’ve run it for a week and it seems OK but we would not recommend it for long term installations. It’s best used by students and artists who want something simple and inexpensive.
Flexible Magnetic Dry Erase Whiteboard – 21cm x 15cm: Use as an everyday whiteboard or as a background for your MagTag. At 21cm x 15cm, this is a great Goldilocks size, not too big, not too small, to decorate your refrigerator or similar magnetic surface. We included these in the MagTag AdaBox and got some extra for stocking since they’re so handy.
Use any dry-erase markers to decorate, not permanent markers like sharpies!
Crazy Circuits Bit Board Kit – Makes micro:bit Lego-Compatible: Welcome to the world of programming and automation with the BBC micro:bit. The Crazy Circuits Bit Board Kit from Brown Dog Gadgets sets you up with everything you need to start making in minutes!
The Bit Board lets makers combine micro:bit and bricks together to create all sorts of amazing projects. No soldering is required, it brings the ease and joy of crafting to electronics and micro:bit!
Like all Crazy Circuits components, the Bit Board snaps onto any LEGO-compatible component. Connect other Crazy Circuits components with the included Maker Tape. Use a ribbon cable to connect sensors, or plug a servo into the Bit Board. Use the built-in relay to control DC motors and devices.
Thanks to MakeCode support, micro:bit offers a much more visual way of working and programming with microcontrollers. The Bit Board Adapter was designed as a solution for teaching programming via micro:bit’s graphic interface without breadboards and jumper cables. The brick plate becomes the canvas for your electronic projects
Adafruit Sensirion SHT40 Temperature & Humidity Sensor – STEMMA QT / Qwiic: Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And finally, we have some that have a true I2C interface for easy reading. The SHT40 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT40 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C.
Unlike some earlier SHT sensors, this sensor has a true I2C interface for easy interfacing with only two wires (plus power and ground!). Thanks to the voltage regulator and level shifting circuitry we’ve included on the breakout It is also is 3V or 5V compliant, so you can power and communicate with it using any microcontroller or microcomputer.
