BeagleConnect Zepto brings a $1 microcontroller board to makers

The BeagleConnect Zepto is an upcoming developer board that, according to BeagleBoard, will cost just one dollar. However, the term “computer” should be taken loosely: the Zepto is not designed to run a desktop operating system, but targets smart home and maker projects instead.

At its core is a Texas Instruments MSPM0L1117 with a 32 MHz ARM Cortex-M0+ CPU, delivering performance comparable to entry-level Arduino boards (available on Amazon). The ultra-low price is made possible by a combination of factors, including the use of a low-cost microcontroller, a simple two-layer PCB, and a reduced set of interfaces—there is no native support for displays or cameras.

The board relies on the license-free mikroBUS standard for expansion, ensuring compatibility with a range of add-on modules while keeping costs down. It also features two QWIIC connectors for easy integration of sensors and actuators. Notably, the Zepto itself can act as a QWIIC device, effectively functioning as an expansion module. The platform is open, and developers are invited to contribute.
