Description

The device NULA Core by Soldered is a compact development board based on the 8-bit ATmega328P microcontroller running at up to 16MHz. It is the successor to the Dasduino CORE board and remains compatible with the Arduino ecosystem and Arduino IDE. Product variant 333379 is supplied without pin headers, allowing the user to choose the preferred mounting and connection method.

The board provides 22 I/O pins: 14 digital and 8 analog, with A6 and A7 operating only as analog inputs. Six PWM channels and UART, SPI and I2C communication interfaces are available. The microcontroller includes 32KB of Flash memory, 2KB of SRAM and 1KB of EEPROM. Programming, serial communication and power can be provided through the modern USB-C connector.

NULA Core also features a Qwiic connector for convenient connection of I2C devices, a 3.3V voltage regulator and a connector for a 3.7V Li-Ion/Li-Poly battery with an onboard charging circuit. The board includes a standard LED connected to pin 13 and a programmable WS2812 RGB LED. Its compact dimensions of only 63 × 22mm make it suitable for both breadboard prototyping and compact final projects.
