The Kumquat is an Allwinner V3s board designed for industrial automation, home automation, IoT projects, robotics, and embedded system development. The Allwinner V3s features ARM Cortex-A7 cores with 64MB DDR2 RAM and 8MB SPI flash storage. Connectivity options include Ethernet, USB-C, isolated CAN-FD, and WiFi/Bluetooth via an ESP32 module.
Additionally, it has eight auto-detecting 12/24V IOs, four relays for controlling external devices, and a real-time clock with battery backup. The Kumquat runs on Buildroot Linux with a mainline kernel and can be programmed with various programming languages making it a great alternative to traditional PLCs.

At the time of writing, I could not find any more additional information about the product. I checked their documentation section for power specs and board dimensions but it’s not present on their docs.
NetCube Systems mentions that the Kumquat runs on Buildroot Linux with Mainline Linux kernel and U-Boot as bootloader, and it can also be programmed in C, C++, and Python 3.x. Additionally, other languages can also be used based on project requirements and developer preference.
The Kumquat Allwinner V3s embedded system board can be purchased for the NetCube Systems Tindie store where it costs around $140.49. Some additional information might also be found on their datasheet.
