When it comes to low-power single board computers, Raspberry Pi Zero is one of the cheapest minicomputers priced at $5. For an additional $5, you can get in-built Wi-Fi and Bluetooth by purchasing Raspberry Pi Zero W. However, to set it up and running, you need accessories like a display, a keyboard, and a mouse.
What about a standalone accessory that turns Raspberry Pi Zero W into a portable Linux PC? Here is the SnapOnAir Raspberry PI ZERO PCB available on Tindie that allows you to add a 2.8 Color ILI9341 TFT display and a TCA8418 I2C chip based keyboard.
You can also connect a buzzer, a mono-audio source or a digital microphone in the 3.5mm audio port provided. Also, the SnapOnAir Raspberry PI ZERO PCB is compatible with nRF24 trx sub-boards.
As a cherry on top, the PCB is available at a dirt cheap price of $10.
Watch this video to see the PCB in action:
A recent update has hinted that the PCB could also support an 1800 mAh battery which makes it further useful in making DIY projects like handheld pagers and other IoT devices.
Next steps are: moving the rpi board to the edge of the main pcb to let people use the micro usb plugs and prepare room for the 1800 mAh battery. Move the 4056 usb charging unit to free some space also. Make a RFM95 variant. pic.twitter.com/Xl3NuLjoIk

A word of caution — there is a lot of DIY involved as it is but a standalone PCB and you need to attach additional accessories to make a functional handheld Linux PC. Nonetheless, the board looks exciting and is a must-buy for DIY enthusiasts.
