Adapter Brings M.2 WiFi Cards To The Pinebook Pro

April 27, 2020 by Tom Nardi 14 Comments

The Pinebook Pro is a considerably more capable machine than the $99 Pinebook released in 2017, but the open source laptop still isn’t exactly a powerhouse by modern standards. The system is intended to compete with mid-range Chromebooks, and to that end, few would argue it’s not worth the $199 price tag. But there’s still room for improvement, and at this price point that makes it a hardware hacker’s delight.

[TobleMiner] has recently released the design files for a drop-in adapter that allows you to install M.2 wireless cards like the Intel AX200 in the Pinebook Pro. With the latest-and-greatest WiFi 6 technology onboard, transfer rates as high as 600 Mbps have been demonstrated on this relatively low-cost Linux laptop. It sounds like there’s a possibility the adapter will be offered officially through the Pine store at some point in the future, but in the meantime, you can always spin up your own copy if you feel the need for speed on your Pinebook Pro.

The adapter takes the place of the official M.2 SSD upgrade board, which means users will need to choose between expanded storage and an upgraded wireless card. But [TobleMiner] hints that a version of the adapter with a second M.2 slot should be possible in the future. The design also features pads to install an optional voltage regulator, as testing has shown that the Pinebook Pro’s 3.3 V line can fluctuate a bit depending on battery level.

We took a close look at the original Pinebook when it was released, and came away cautiously optimistic. The Pro model appears to be an improvement in every way imaginable, and upgrades like this show just what’s possible when users are free to explore their hardware.

Tiny FPGA Board Fits In Your Laptop

There are a bunch of FPGA development boards to choose from, but how many will fit inside your laptop? The PicoEVB is a tiny board that connects to a M.2 slot and provides an evaluation platform for the Xilinx Artix-7 FPGA family.

This minimalist board sports a few LEDs, a PCIe interface, an integrated debugger, on-board EEPROM, and some external connectors for hooking up other bits and pieces. The M.2 connector provides the board with power, USB for debugging, and PCIe for user applications.

A major selling point of this board is the PCIe interface. Most FPGA boards with PCIe will cost over a grand, and will only fit in a large desktop computer. The lower priced options use older FPGAs. The PicoEVB is tiny and retails for $219. Not a bad deal when the FPGA on-board costs nearly $100.

The PicoEVB is also open source. Design files and sample projects can be found on Github.
