Piksey – A Newcomer in the Battle of World’s Smallest Arduino Compatible Board

The World’s Smallest Arduino has been one of such title that is heavily contested by so many Arduino compatible boards. We have seen several boards that have claimed the title in one way or the other such as boards like pico, µduino, beetlenerdonic or even digispark. µduino seems to be the world smallest Arduino compatible board among all measuring at only 0.5″ by 0.5″.

So if µduino is the smallest, what is Piksey? Piksey is most likely the World’s Smallest Arduino 328 Clone measuring about 0.8 inches by 0.8 inches. Even though the Piksey board is slightly larger than the µduino version, it is still the true smallest Arduino clone. The Atmega 328P processor powers the Arduino Uno board and the same processor is what runs on Piksey, unlike µduino which is based around Atmega32U4 processor.

Just like the Arduino Uno, the Piksey extends all the 13 digital IO pins and all 5 analogue pins out; this will make the board fully working with all existing Arduino Uno based codes, libraries, and even shields. So yeah, the Piksey is the World Smallest Arduino 328 Clone.

The Piksey is a new Arduino compatible development board that is developed by BitsNBlobs and currently running a kickstart campaign. The new board is a tiny board as compared to the real Arduino Uno board and still pack similar features. The board is as small as a crown cap and yet powerful.

At the heart of the Piksey board is the all famous Atmega328P running at 16MHz, 32KB of Flash, 1KB of EEPROM, and 2KB of SRAM. Just like the Arduino Uno board, the Piksey board is also a 5V rated board. It is breadboard friendly and provides up to 16 pins for digital and analogue purposes.

The board is powered via a micoUSB port and can take in a max of 18V through the inbuilt voltage regulator. The board comes with an inbuilt USB-serial converter for programming the device.

Below are summarized the features of the board:

  • Size:  At 20x20mm, the Piksey core is smaller than a crown cap!
  • Processor: ATmega328P @ 16MHz, 32KB Flash, 1KB EEPROM, 2KB SRAM
  • Voltage Regulator:  18V DC wide range input voltage
  • Breadboard Compatible – 16 breadboard compatible pins, rest available on 1.27mm header
  • Connectivity: micro USB for programming and power
  • Others: Contains power and general purpose LED
  • Reset Switch: A Tactile switch for module reset
The Piksey board will find use in applications that need to work with tight spaces, and it even comes without any headers. The Piksey crowdfunding campaign is now active on Kickstarter with pledges starting from £8 to £20.

NanoPi K1 Plus – A New Open-spec SBC By FriendlyElec Powered By Allwinner H5 SoC

FriendlyElec has launched a $35 open-spec “NanoPi K1 Plus” SBC. The new NanoPi K1 Plus is a media-rich board, that switches from the Amlogic S905 SoC (found on the Odroid-C2) to an Allwinner H5 SoC, which is used in several other NanoPi boards. Both the SoCs have 4x Cortex-A53 cores and a Mali-450 GPU, but the H5 has a lower clock speed of 1.4GHz instead of 1.5GHz.

The new board has almost similar footprint to NanoPi K2, 85 x 56mm. It has an identical feature set and layout as the RPi 3 and Odroid-C2. FriendlyElec has swapped out the K2’s WiFi/Bluetooth module for a 2.4GHz WiFi-only chip and has reduced its HDMI 2.0 port to an HDMI 1.4 that has its 4K support only at 30fps max. The K1 Plus has also decreased one of the USB 2.0 host ports, leaving 3x USB 2.0 ports total along with a micro-USB OTG port with power input support. The previous DC-in jack has been removed.

On the better side, the K1 Plus add some multimedia features. There’s a new DVP camera interface, an onboard mic, and a 3.5mm audio jack that also outputs the CVBS signals. CVBS was previously available only via the continuing, Raspberry Pi-compatible 40-pin expansion connector.

There are 2GB RAM, a microSD slot, eMMC socket, and GbE port. Once again, you get an IR receiver, a heatsink, and a debug header, among other details. The open-spec board is available with schematics and other documentation, as well as images for Armbian and the Ubuntu Core based OS, FriendlyCore.

Spec list for the NanoPi K1 Plus:

  • Processor: Allwinner H5 (4x 64-bit Cortex-A53 cores @ 400MHz to 1.4GHz) with Mali-450 GPU
  • Memory/storage: 2GB DDR3 RAMMicroSD slot for up to 128GB (bootable)eMMC socket
  • Wireless: 2.4GHz 802.11b/g/n; PCB antenna
  • Networking: Gigabit Ethernet port (Realtek RTL8211E)
  • Media I/O:
    • HDMI 1.4 port (4K@30fps video and audio)
    • DVP camera 24-pin header
    • 3.5mm audio jack with CVBS output
    • Onboard Mic
    • I2S/PCM via 7-pin header
  • Other I/O:
    • 3x USB 2.0 host ports
    • Micro-USB 2.0 device/OTG port with power cable
    • Serial debug 4-pin header
    • 40-pin RPi 3 compatible expansion connector (I2C, GPIO, UART, PWM, SPDIF, SPI)
  • Other features: LEDs; IR receiver; GPIO button; heatsink; optional acrylic case
  • Power: 5V2A DC input via micro-USB; PMIC
  • Operating system: Images for Armbian and FriendlyCore (based on Ubuntu Core) with Linux 4.x

The NanoPi K1 Plus is available now for only $35. More information may be found on FriendlyElec’s NanoPi K1 Plus shopping and wiki pages.
