Description

The NULA Core board uses an 8-bit ATmega328P microcontroller operating at up to 16 MHz and maintains compatibility with the Arduino IDE and common libraries developed for the Arduino platform. The board provides 22 I/O pins, including 14 digital lines and 8 analog inputs, with A6 and A7 supporting analog input only. The microcontroller features 32 KB of Flash memory, 2 KB of SRAM, 1 KB of EEPROM, as well as UART, SPI, and I2C interfaces.

The integrated USB-C connector, Qwiic connector, and Li-ion battery charging circuit expand the board's capabilities in stationary and portable projects. NULA Core operates at 5 V and includes a 3.3 V regulator, an LED connected to pin 13, and an addressable WS2812 RGB LED. The version with female pin headers allows wires and modules to be connected directly to the board without soldering. Dimensions of 63 x 22 mm facilitate integration with breadboards and compact electronic assemblies.
