Centron Design’s CT1832 Real.Pi is a RealTek RTD1619B SBC that mainly follows the Raspberry Pi 3 Model B form factor and is designed for AIoT applications, vehicle-mounted central control, entertainment/game equipment, and digital signage.
It follows the RTD1619B-powered XpressReal T3 SBC based on a smaller form factor, which was introduced a few weeks ago by Fyde Innovations, with support for the Chromium-based FydeOS operating system. The CT1832 Real.Pi board is equipped with 4GB RAM, 16GB eMMC flash, an HDMI 2.0 port, a Gigabit Ethernet port with optional PoE, optional dual-band WiFi and Bluetooth 4.2 module, a 16-pin PCIe x1 connector, and a 40-pin GPIO header, among other features.

Centron mentions support for Ubuntu and Yocto, but I suppose FydeOS might also work on this board. The company also highlights AI acceleration leveraging the NPU for AI Vision tasks. Sadly, there’s no public documentation, and the company probably provides software and related resources once a customer has purchased a board.
While the ReaTek RTD1619B SoC has been around for a few years, notably in the TerrasMaster F2-212 NAS, I had never seen a proper block diagram for the SoC, so here is one…
Centron Design could not provide pricing information for the board. As a side note, they also offer the CT1831 SMARC module based on the RealTek RTD1619B SoC, so I assume the Raspberry Pi-inspired CT1832 Real.Pi SBC could be used for evaluation, and the CT1831 could be integrated into commercial AIoT products. The products page has limited information about a different CS1832 board with two Ethernet ports and the module (note: scrolling down is needed), but Centron informed CNX Software that they were currently rebuilding their website.

The description and the photo do not really match. The description implies 4 USB ports and 1 Ethernet, but the photo shows 2 USB3 and 2 RJ45. It’s possible they copy-pasted more data from another board’s spec. Also what looks like a CR2032 battery holder looks misplaced, I wonder if it’s possible to put an enclosure on top of this since it seems to extend outside of the board on the left.
I was super confused. Now I see the product on the website is called CS1832 (first photo, somehow with silkscreen reading “CT1832_LPDDR4…”), but the PDF documentation I was given is for the CS1832. I’ll ask for clarification.
So it’s the dual Ethernet version that’s the old one (removed from post now), and the new one is with one Ethernet, and four USB ports:
OK now that makes more sense. A perfect example of bad marketing by companies which try hard to make their products differ by a single digit or letter (like amlogic does) where in the end each time you see a new product, you first believe it’s the boring old one.
IR receiver present but no audio ?? – weird decision. No RTD1619 manual available in public which means no sense to even try it
Audio is available through HDMI.
Yep, only out. The chip itself contains as I2S as DAC for audio but nothing is routed externally. Only IR 😉
