Launch of Ghost Edge AI Sticker: A Flexible Smart Sensor Node
The Ghost Edge AI Sticker, a flexible smart sensor node, utilizes Nordic Semiconductor's nRF54L15 SoC and integrates a 6-axis IMU and PDM microphone. Open-source resources including KiCad files and firmware are available on GitHub, although a design flaw with the microphone's footprint may impact audio validation.

The Ghost Edge AI Sticker, launched on June 20, 2026, features a lightweight design centered around the Nordic Semiconductor nRF54L15 wireless SoC. It employs a dual-core architecture consisting of an ARM Cortex-M33 and a RISC-V FLPR remote core for efficient sensor data handling and BLE communication.
Open-source resources including KiCad schematics, Gerber files, and firmware are available, facilitating small-batch prototyping. However, a noted 180-degree footprint rotation error on the PDM microphone has hindered audio feature validation, prompting caution for manufacturers in verifying component datasheets. The project, supported by the NextPCB accelerator, may influence future wearable AI applications but highlights the necessity of thorough design checks.
