Features
- Full IO set: all the GPIO and programming pins are present
- Compact design: the board is 16.4x25.3 mm with ≈4.8 mm of total height
- Ultra efficient: featuring TLV62569 with ≥92% efficiency at (almost) any load
- 1V8 pin can be used as both input (if VIN not connected) and output (up to 1.5A)
- 4 programmable LEDs (200 µA) that can be isolated to free the pins
- On-board "reset" switch and an additional general purpose button (High/High-Z)
- Impedance of (almost) all traces is close to 50Ω
- Board-to-board connector with programming, power and GPIO pins

Questions
How big is the Nrf54l module PCB?
It measures 16.4 × 25.3 mm and has 6 copper layers, 1.19 mm thick.
What parts does the Nrf54l module use?
134 parts, built around the NRF54L15-QFAA-R, TZ-P2-0402RTIA1-0.45T, MLG0603P2N7CT000 and BM28B0.6-10DS/2-0.35V(51). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Nrf54l module KiCad files?
From the efogdev/nrf54l15-module repository on GitHub, at the commit this page was made from: the board is nrf54l-module.kicad_pcb and its schematic companions/flex/usb-and-battery/usb-and-battery-companion/usb-and-battery-companion.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nrf54l module design in my own project?
Its repository states no licence, so its author keeps all rights: ask efogdev before reusing the design.
