Smallest Developments Boards

By Harshvardhan Mishra Feb 11, 2020 #Boards

In this article we discuss some Smallest Developments Boards. In 2019, it’s unsurprising that at least one company, namely Nionics, made a small Arduino compatible board called Atto. But somebody must have forgotten to do a web search, as BitsNBlobs Electronics created their own tiny Arduino compatible board, also named Piksey Atto. What is Atto ? – Atto is a unit prefix in the metric system denoting a factor of 10−18. A Random list of Smallest Developments Boards is given below.


Smallest Developments Boards


Nionics Atto

According to nionics.com Atto is the world’s smallest Arduino compatible board! It is based on the ATmega32U4 microcontroller and comes with reset push-button as well as an RGB (rainbow) LED controlled by 3 PWM channels.

Atto’s tiny profile allows it to fit into any miniature projects! Perfect for wearables and portable devices. There are also available two different types of breadboard friendly expansion boards and all products from nionics.com are available for pre-order. According to website, Additional accessories and add-ons, such as battery power shields, will be coming soon!

ATTO board specifications:

  • MCU – Microchip (Atmel) ATmega32U4 8-bit AVR microcontroller @ 16 MHz with 32KB flash pre-loaded with Arduino Leonardo bootloader (~4KB footprint), 2.5KB SRAM, 1KB EEPROM
  • Expansion – 2x 8-pin 1.27mm pitch through holes for 12 digital I/Os, 4x PWM, and 4x analog input channels. UART, SPI, I2C/TWI, and ISP interfaces are also supported
  • USB – Micro USB port for power and programming
  • Misc – RGB LED via 3x PWM, Reset push-button
  • Power Supply – Input: 4-13V DC via Vin, 5V via micro USB port; 3.3V operating voltage
  • Dimensions – 11.5mm x 10.4 mm
  • Weight – 0.68 grams

Now 2020, I have no information about shipping.

Piksey Atto

The Piksey Atto from BitsNBlobs Electronics is a particularly compact developer board, which according to the manufacturer is compatible with the extremely popular Arduino system. Piksey Atto is cost-effective. Specially, This tiny USB dev. board is designed for makers. It can be soldered onto PCBs, used with a breadboard or by itself. Piksey Atto, and based on the same Microchip ATmega32U4 8-bit AVR MCU.

The company also provides demo projects for the board. According to the manufacturer, the Atto is compatible with Arduino IDE 1.0+ upon delivery, which means that the tried and tested tools can be used. The lean board is currently being financed as part of a crowdfunding campaign, and delivery is scheduled for May.

Piksey Atto specifications:

  • Core: ATmega32U4 microcontroller running at 16MHz
  • Memory: 32KB Flash, 2.5KB SRAM, 1KB EEPROM
  • Digital I/O: 11
  • Analog Input: 4
  • PWM Channels: 4 (+ more with software)
  • Communication: USART/SPI/I2C (TWI)
  • Operating Voltage: 5V
  • Dimensions:  0.5″x0.8″ (12.70mmx20.32mm)
  • Weight: 1.3g (0.04oz)
  • Software: Works out of the box with the Arduino IDE 1.0+ (Win/OSX/Linux)

Piksey Atto is about twice the size and weight of Nionics Atto, lacks LEDs, and a reset button, but offers breadboard compatibility and castellated holes that make it easier to solder to your own baseboard or a protoboard.

Beetle

Beetle is another tiny Development Board. Actually it is minimalized version of Arduino Leonardo, and has same powerful functionalities as Leonardo. It derives its core notion from minimalism without compromising functionality. Beetle can use in DIY Arduino Projects and and wearable projects etc. Some features of this board are given below:

  • 20mm X 22mm compact size
  • Direct downloading and testing via Micro USB
  • V-shaped large-size gold-plated IO ports make it convenient for the user to twist wires upon, and can also be directly sewn on clothes with conductive thread.
  • Two honeycomb shape gold-plated power interface
  • Magic light blue soft BLINK indicator

It comes with Atmel AtMega32u4 (datasheet) @16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins and 4 pwn pins and a microUSB connector. Beetle Board aims to solve problems of low-cost controllers, ease-of-using properly, and to provide a low cost solution for disposable projects, such as DIY projects, workshops and educational. For students and makers who can not afford too much on hardware purchasing, Beetle can be a great solution for them.

Specifications

  • Microcontroller: ATmega32u4
  • Clock Speed: 16 MHz
  • Operating Voltage: 5V DC
  • Digital I/O Pins: 10
  • PWM Channels: 4
  • Analog Input Channels: 5
  • UART: 1
  • I2C: 1
  • Micro USB: 1
  • Power Ports: 2
  • Flash Memory:  32 KB of which 4KB used by bootloader
  • SRAM:  2.5 KB
  • EEPROM:  1 KB

Arduino PICO

The company says that Arduino PICO is the smallest Arduino compatible board ever, since it is 0.6″ x 0.6″ inch sized (~15mm squared). This tiny fully-fledged arduino-compatible board has a Leonardo-compatible 16MHz ATMEGA32U4 chip and a micro-USB port.

Size matters! PICO is making big dreams of making small things a reality. A mini fully-fledged arduino-compatible has been a dream for many enthusiast hardcore DIY-ers, and with the size of only 0.6”x0.6”, the PICO shouts to be your best new friend around. Can you imagine the possibilities already? pico

The 16MHz ATMEGA32U4 integrates 2.5KB SRAM and 32KB flash, 4KB of which the bootloader uses. The 1.1-gram PICO has 8x digital I/O pins, 3x analog inputs, a PWM channel, and a reset button. In addition, the board has a 7-12V power with 5V operating voltage, where each I/O pin uses 40mA.
