XIAO nRF54L15 Sense board

Family: Pro boards · Languages: Arduino C++

Nordic’s nRF54L15 — a Cortex-M33 at 128 MHz with RRAM instead of flash — in the XIAO footprint, Sense variant, with a 6-axis IMU (LSM6DS3TR-C) on board. The in-browser engine boots the firmware the community nRF54 Arduino core produces; Serial reaches the monitor through the board’s own USB bridge.

The IMU is live: press Sensors on the canvas toolbar and drag the Tilt pad. As on the real board, the part only answers once the sketch has switched on its supply rail (IMU_MIC_PWR). The radio is not emulated.

  • Blink — the shortest check that the board and toolchain work.
  • OLED over I2C — an SSD1306 on the header pins.
  • Knob and button — analog in, digital in, an LED out.
