A new open source Espressif ESP32-based board offering a form factor similar to popular single board computers such as the Raspberry Pi has been launched via the Crowd Supply website this month and takes the form of the Obsidian ESP32. Pledges are available from $35 which includes free shipping throughout the United States, with international shipping also available for an extra $10 if required.
The Obsidian ESP32 offer is a footprint compatible with Raspberry Pi cases and can be used with ready-made Raspberry Pi peripherals as well as supporting Arduino IDE, Espressif IDF, or MicroPython and is “leveraging the strong open source software community around the ESP32”.
“Obsidian ESP32 consumes significantly lower power than typical Linux single-board computers because it uses a microcontroller running either user code on bare hardware or via a real-time operating system. This allows for a longer battery life and reduced operating energy footprint overall. It shares the form-factor with the popular Raspberry Pi and countless other single board computers, so the end-user can rest easy knowing their project has the flexibility to be easily ported to or from a Linux SBC as the need arises.”
