Seeed Studio Unveils Next-Gen Wireless Development Boards Built Around Nordic's nRF54LM20A
TECHWORLD ·
✦ AI Summary
Seeed Studio launched two ultra-compact wireless development boards aimed at battery-powered IoT applications, the XIAO nRF54LM20A Sense and the XIAO nRF54LM20A.
Both products share the Nordic Semiconductor nRF54LM20A SoC and nPM1300 PMIC, while the XIAO nRF54LM20A Sense adds a 6-axis IMU and a digital microphone.
Supported environments include the nRF Connect SDK, Zephyr RTOS, and PlatformIO, and Seeed Studio plans to add an XIAO nRF54LM20B version in the future.
Seeed Studio on the 1st launched two ultra-compact wireless development boards aimed at battery-powered IoT applications. The products are the "XIAO nRF54LM20A Sense" and the "XIAO nRF54LM20A."
The products target wearables, smart home, industrial IoT, and smart sensing applications. Both boards are built around Nordic Semiconductor's nRF54LM20A SoC and the nPM1300 PMIC.
This combines wireless connectivity, processing performance, battery charging, and power management in a single small form factor. Seeed Studio said it has introduced a configuration that integrates these functions for battery-powered IoT applications.
Among them, the XIAO nRF54LM20A Sense additionally includes a 6-axis IMU and a digital microphone. The product is designed for voice, audio, motion, and gesture applications, with the goal of enabling prototyping without extra hardware.
This configuration combines the nRF54LM20A's computing resources with multi-protocol wireless capabilities. The nRF54LM20A comes with a 128MHz Arm Cortex-M33 processor, 512KB RAM, and 2MB on-chip NVM, and it features a 128MHz RISC-V coprocessor. Its wireless functions are multi-protocol 2.4GHz, supporting Bluetooth LE, Bluetooth channel sounding, Bluetooth Mesh, Thread, Zigbee, and Matter. Its proprietary protocol supports up to 4Mbps over 2.4GHz.
On power management, the nPM1300 PMIC integrates battery charging, voltage regulation, power management, and Fuel Gauging functions. This reduces the number of separate power management components, enables efficient power delivery, and allows control over system power states.
By combining the nPM1300 with the nRF54LM20A's low-power architecture, the company focused on securing battery life for small always-connected devices.
Kevin Yang, Seeed Studio senior product manager and head of the maker team, said that after Seeed Studio previously developed XIAO products based on the nRF52840 and nRF54L15, it can advance its wireless lineup with the nRF54LM20A. He said the nRF54LM20A is the optimal choice for next-generation XIAO products because it offers improved processing performance, larger memory, better power efficiency, and advanced wireless features.
The two development boards also offer 28 GPIOs, USB Type-C, 8MB of external flash, NFC, and an external antenna interface. They also offer enhanced security features.
The nRF54LM20A SoC includes secure boot, secure firmware updates, secure storage, a TrustZone-based TEE, side-channel protection, cryptographic acceleration, and tamper detection. The company said these security features are intended to strengthen the security of IoT devices deployed in real-world environments.
Supported development environments include the nRF Connect SDK, Zephyr RTOS, and PlatformIO.
Kevin Yang said the engineering team was able to efficiently integrate the nRF54LM20A and nPM1300 into the 21x17.8mm XIAO form factor by using the nRF Connect SDK and Zephyr RTOS, the software frameworks supported by the engineering team, along with hardware technical documentation and reference designs.
Kevin Yang said the development boards make it easier for developers to move from proof-of-concept to finished prototypes, as they can use compatible expansion boards, accessories, tutorials, open-source examples, and the XIAO ecosystem.
Seeed Studio plans to expand the lineup by adding an XIAO nRF54LM20B version in the future, widening its options for developers of next-generation low-power edge AI devices.
