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.

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.
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.
