Neutrino 3.0: The 32-bit Arduino Zero compatible!

The Neutrino 3.0 is an inexpensive, open source, miniaturized version of the Arduino Zero! Featuring a 32-bit ARM processor running at 48MHz, and boasting 32K of ram, the Neutrino is far more capable than your typical Arduino. And because it has the same processor and pinout, all libraries written for the Zero will work on the Neutrino without any modification!

Technical Specs

  • Microcontroller: Atmel ATSAMD21G18 ARM Cortex M0+
  • Clock speed: 48 MHz
  • Operating voltage: 3.3V
  • I/O pin limits: 3.3V, 7 mA
  • Digital I/O pins: 14, with 12 PWM
  • Analog input pins: 6, 12-bit ADC channels
  • Analog output pins: 1, 10-bit DAC
  • Flash memory: 256 KB

  • Voltage regulator: 3.7-5.5V input / 3.3V, 300mA output
  • Dimensions: 1.4 x 0.7″ (36mm x 18mm)

The project is live on kickstarter and has 14 days to go.

Pixel 2.0, Arduino Zero-Like Board With Smart Display

The Pixel is an Arduino-compatible smart display, combining a 32-bit Cortex M0+ MCU with 32K of RAM, a 1.5″ 128×128 color OLED screen, and a microSD slot all in one package.

This is Rabid Prototypes’ second iteration of Pixel, which originally raised nearly $10,000 on Kickstarter back in 2015. The board offers a number of potential use cases, ranging from wearable devices, to sensor data monitors, to retro video game consoles.

The Pixel is compatible with Arduino’s SPI and SD libraries, as well as Adafruit’s graphics library, which provides functions for blitting images, drawing primitives like lines and circles, and even includes bitmapped font support.

Additionally, if you ever need to modify the fuses or bootloader, the Pixel features a standard SWD header that can be used with Microchip’s Atmel-ICE development tool.

Here are the technical specifications of Pixel:

  • Microcontroller: Atmel ATSAMD21G18 ARM Cortex M0+
  • Clock speed: 48 MHz
  • Operating voltage: 3.3V
  • I/O pin limits: 3.3V, 7 mA
  • Digital I/O pins: 14, with 12 PWM
  • Analog input pins: 6, 12-bit ADC channels
  • Analog output pins: 1, 10-bit DAC
  • Flash memory: 256 KB
  • SRAM: 32 KB
  • Voltage regulator: 3.7V – 5.5V input / 3.3V, 300mA output
  • PCB Dimensions: 1.8 x 1.8″ (46mm x 46mm)
  • Display : 128×128 16-bit color 1.5″ (38mm) OLED w/ SSD1351 driver

Pixel is now live on Kickstarter! you can get your own Pixel 2.0 for $75 or two for only $135. The campaign still has 12 days to go, check its video to know further details about Pixel 2.0:
