This is our take on an microcontroller with a RFM69HCW packet radio transceiver plus built in USB and battery charging. Its an Adafruit Feather M0 with a 900MHz radio module cooked in! We have other boards in the Feather family, check'em out. This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically.

This Japanese upgrade to the classic $5 solder sucker is a joy to use. Since the tip is rubbery soft silicone you don't have to worry about it melting. You also get a long tube in case it gets clogged or dirty.

The LEDs are individually addressable, so you can use it to display anything in a 9 x 14 grid. Scroll text, play games, display images, or anything else you want to do. This kit you will need to assembled/ solder it together.

We wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino!

We picked up this box because we like the machinable ABS plastic body and tough clear polycarbonate cover, the built in weatherproof gasket seal, and the easy-open screws that can be taken apart as many times as you wish without worrying about cracking or stripping.

The enclosure comes as 6 laser cut acrylic pieces, 4 plastic standoffs, 8 hex-nuts and 8 1/2" 4-40 screws. Assembly is easy, and requires only a Phillips screwdriver. Once assembled, the box has lovely engraved ends with cut-outs for the DC power, Ethernet, microSD card, USB host and USB debug ports.

Instead of a L293D darlington driver, we now have the TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.

PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you'll be able to keep your power-hungry project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects.

24 ultra bright smart LED NeoPixels are arranged in a circle with 2.58" (65.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim.

This is the LoRa 9x @ 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings.

The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).

This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.
