nRF54L Arduino Core project brings Arduino support to Nordic Semi nRF54L wireless SoCs - CNX Software

nRF54L Arduino Core is an open-source project designed to bring Arduino support for Nordic Semiconductor nRF54L wireless SoCs, starting with Seeed Studio’s XIAO nRF54L15 (Sense) and XIAO nRF54LM20A (Sense) boards, as well as compatible Holyiot nRF54L15 modules.Since the launch of the nRF52840-based Arduino Nano 33 BLE board in 2019, Nordic nRF52 wireless microcontrollers have been officially supported by the Arduino IDE. However, it’s not quite the case for the newer nRF54L Cortex-M33 microcontrollers. Lolren has decided to change that with the unofficial nRF54 Arduino core project.nRF54L Arduino Core highlights:

Dual-core access – Use the 128 MHz Cortex-M33 application CPU and the VPR RISC-V coprocessor without adopting a vendor RTOS

Wireless

Bluetooth LE support – Peripheral, central, dual-role, GATT server/client, HID, BLE UART, PHY/DLE/MTU control, LE Secure Connections, bonding, OOB, Numeric Comparison, privacy/RPA, and CSRK signed writes

Experimental support for
