The 52Pi NVdigi is another PCIe expansion board for the Raspberry Pi 5 which integrates HiFiBerry Digi+ to provide high-quality S/PDIF output. It also features an M.2 PCIe x1 slot that supports NVMe 2242/2230 SSDs. Furthermore, it offers an optical output (TOSLink) and an RCA output for versatile audio connections.
The HiFiBerry Digi+ is a high-quality S/PDIF output for the Raspberry Pi. It uses the I2S sound port that connects directly to the CPU without the need for an additional USB conversion. It supports sample rates up to 192kHz/24bit.
52Pi NVdigi Expansion Board Specification:
- HiFiBerry Digi+ Integration – Provides high-quality S/PDIF output for Raspberry Pi 5.
- Direct I2S Connection – Connects directly to the CPU via the I2S sound port for optimal audio.

Previously we’ve seen HATs for SSDs like the Mcuzone MPS2280 M.2 NVMe HAT, Mcuzone MP4GM 4G LTE HAT, and the Sixfab 5G Modem Kit along with HATs for Wi-Fi 7 and Google TPU. However, this is the first time we have seen a HAT that combines audio support with M.2 storage.
The company mentions that this device is perfect for those who love high-quality sound and need more storage for their Raspberry Pi 5 projects. Mostly, this little HAT targets those who want to build their own online media center. The company also provides a wiki page with further hardware details and instructions to enable it in Raspberry Pi Official OS.
The package includes one 52Pi NVDigi board, a 40-pin PC104 header, a 40mm PCIe FFC cable, four M2.5 x 15mm copper pillars, eight M2.5 x 4mm flat head screws, and an M2.5 screwdriver, providing all necessary components for setup. The 52Pi NVdigi Extension Adapter Board is priced at $39.99 and it’s available for pre-sale on the 52Pi online store.

Doing two things with one RPi 5 HAT like this seems like a good idea (disclaimer: only to the extent where using RPi 5 is a good idea at all).
no case – no joy
