The BIGTREETECH Pi 2 is a single-board computer with a 1.8 GHz Rockchip RK3566 quad-core ARM Cortex-A55 processor. While it looks a bit like a Raspberry Pi Model B, this little has a few things that Raspberry Pi’s computers lack including support for up to three storage devices (eMMC, SD card, and M.2 2242 PCIe 2.1 SSD) without the need for any add-on boards.
BIGTREETECH’s new CB2, meanwhile, is a Compute Module with the same basic features in a more compact design (but you’ll need to pair it with a carrier board if you want full-sized ports). The new BIGREETECH Pi 2 is available now for $50, while the BIGTREETECH CB2 sells for $40.
The company is positioning these new systems as upgrades over BIGTREETECH’s first-gen models, which launched a few years ago with 1.5 GHz Allwinner H616 quad-core ARM Cortex-A53 procesors.
Not only do the new models have more processing power, but they also gain support for USB 3.0, Gigabit Ethernet, and dual-band WiFi, among other improvements (the previous-gen topped out at USB 2.0, 2.4 GHz WiFi, and 10/100 Mbps wired networking).
At the moment the only versions of the boards that are available for purchase feature 2GB of LPDDR4 memory and 32GB of eMMC storage. But with an onboard microSD card reader and M.2 2242 slot, you should be able to upgrade the storage on the BIGTREETECH Pi 2 pretty easily.
The company’s spec sheet also indicates that the systems are configurable with anywhere from 1GB to 8GB of RAM, and 8GB to 128GB (or more) of eMMC storage. But there’s no option to actually buy any other configurations at the moment.
Here’s a run-down of some key features for the new boards:

Another Chinanother Chinese company that is careful not to show it too much. China, a country whose avowed goal is to wage economic war against the West. We are like a bunch of idiots, we give them our money!ese company
Just get a Radxa Zero 3W for half the price… micro SD works just fine… or splurge for the on-board emmc. Not sure who this board is for.
These are for 3D printers. The CB2 plugs into their Manta M8P (and similar) boards. It makes it a perfect pairing for running Klipper. The full board has 12-24v input to match common 3D printer builds.
Thx… makes sense that this would be part of some other system.
