Popcorn Computer’s Popstick may look like a USB flash drive, but it’s actually a USB computer running Linux on an Allwinner F1C200s ARM9 processor with 64MB RAM on-chip.
The PopStick support USB gadget mode so it can appear as all sort of USB devices such as a scriptable USB Keyboard and Mouse, a mass storage device, or even an Ethernet-connected computer using USB Ethernet which you can access with SSH.
- SoC – Allwinner F1C200s ARM926EJ-S (ARMv5TE) processor @ 533 MHz with 64 MB Embedded DDR1
- 128 MB SPI NAND Flash for OS
- Micro SD Card Slot
- Both storage devices are bootable
- 1x USB Type-A connector with support for USB Gadget mode, so the board can be seen as a USB Ethernet, Serial, Mass Storage, HID (keyboard/mouse), etc…
- 1x micro USB connector for serial Console
- Power Supply – 5V via USB Type-A port
- Dimensions – N/A
If Popcorn Computer rings a bell, it’s because it was Source Parts’ attempt to reproduce Next Things’ C.H.I.P board, and the company simply kept the name for the Popcorn Computer PopStick. Hardware and software documentation can be found on a dedicated website, and the PDF schematic also shows an FEL switch, a Reset switch, and a status LED, as well as a Qwiic connector that does not appear to be populated.
On the software side, the internal 128MB Flash is preloaded with a simple Linux environment that sets up a Gadget USB Ethernet and USB Serial device on boot to easily let you SSH to the board after connection to the host or access the console through the USB serial gadget. But you can also customize the Linux OS since Source Parts provide the PopStick Buildroot environment to help you create your own OS easily. If you’re not familiar with buildroot, tutorials explaining how to use it will soon be provided. As a side note, I found the PopStick in Linux 6.4 changelog, so mainline Linux might work but needs to be tested.
Source Parts is selling the PopStick for $29 on the Popcorn Computer shop. While the form factor is rather original, the price is quite higher than other F1C200s boards we’ve come across, such as the MangoPi R3 ($21.90) or the Lctech Pi F1C200s ($13.80).
