We have seen various SBCs being released since late 2020 to 2021, however, 10 of these SBCs will be summarized alphabetically below.
The Yún rev. 2 is a reboot of its original, MIPS-based Arduino Yun, with the power of a Linux based system that enables advanced network connections and applications. It offers a WiFi-enabled, 400MHz AR9331 SoC running OpenWrt Linux with an ATmega32U MCU that runs Arduino code. The board is also equipped with a microSD slot and USB host, micro-USB, and 10/100 Ethernet ports. Connecting to your WiFi or wired network is easy thanks to the Yún Web Panel and the dedicated ”YunFirstConfig” sketch. The Web panel enables you to manage your shield preferences and upload your sketch. The Yún rev. 2 utilizes the Bridge library and so extends the board capabilities by using the Linux processor. The board is also open source.
