9 Tiny Microcontroller Board Options to Complement Your Arduino Uno

The venerable Arduino Uno is the de facto standard in microcontroller development boards, but there are also other boards that can be hidden in a project to make it “smart.” Some even provide extra features like built-in Bluetooth or WiFi capabilities. While the Uno will certainly be used for years to come, due to its familiar form factor and available accessories, here are nine other options in even smaller form factors to hide in your project.

Arduino Nano

If you like the Arduino Uno, but just want it smaller, then the Arduino Nano provides very similar specs. While the Uno board measures 68.6 x 53.4mm at 25g, the Nano measures only 18 x 45mm at 7g. The Nano gets its size down by eliminating the DC power jack and utilizing Mini-B USB. (more…)

Particle Mesh – A Mesh-Enabled IoT Development Kits.

Particle, which has been known for its collection of  IoT focused development boards, and its Internet of Things (IoT) platform (Particle Cloud) has launched a new set of mesh network-enabled IoT development kits called Particle Mesh. Particle Mesh is expected to provide developers more insight into implementing mesh networking technology. They help to collect sensor data, exchange local messages, and share their connection to the cloud.

Particle Mesh features a new family of mesh-ready devices with Wi-Fi, BLE and LTE connectivity and also integrated with the Particle device cloud. Particle mesh consists of three main boards: The Argon, The Boron, and the Xenon. Each of these Particle Mesh boards has at least one form of outside connectivity option (LTE/3G/2G, Wi-Fi or Bluetooth) and an onboard mesh network hardware to facilitate setting up a mesh network for local communications between sensors and other particle mesh boards. All three devices are built around the Nordic nRF52840 MCU + BLE + mesh radio and follow the Adafruit Feather specification making it compatible with most Adafruit FeatherWing hardware accessories.

Paperino, The ePaper Display Shield

ePaper displays  (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle,  for their low power consumption due to the  to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is only required while updating the display with new information, otherwise there won’t be any power consumption.

Providing such revolutionary displays to your applications will be a professional approach. For this, a new crowdfunding campaign is providing Paperino, an easy-to-use, micro ePaper shield for the Particle & Arduino community. Paperino simplifies driving ePaper displays with clean, simple, and short script examples.

Thanks to the plug-and-play shield for particle family, Paperino can be used with the following boards: Photon, Electron, or Bluz without manual wiring. It can also be wired easily to be connected with Arduino and other compatible boards.

Paperino Features

Glass-free Display

Paperino is lightweight and thinner than other ePaper products because it uses a glass-free ePaper display from Plastic Logic. It weighs 1.2 grams and is only 0.5 mm thick.

Supports Four Gray Levels

Unlike many other ePaper products out there, Paperino can support four gray levels instead of two (black and white).

Fast, Partial Updates

You don’t have to wait for slow, full screen updates to load. With Paperino, you can quickly update only parts of the screen.

Accelerometer

The integrated accelerometer lets you interact with your Paperino in all sorts of ways, including tap sensing. Tap sensing capability can trigger screen updates or wake up your microcontroller.

Paperino Specifications

The Paperino breakout board can be used for manually wiring your favourite, Arduino-compatible microcontroller with 3.3 V and >4kb of free RAM.

  • Resolution: 148 x 70 px
  • Pixel density: 150 ppi
  • Grey levels: 4
  • Weight: 1.2 g
