Integrated 500-mA boost and 1-A buck converters and automatic power switching circuitry.

Powered via USB or externally (3.3V to 5V).FLASH: 256 kB (248 kB due to integrated bootloader).CPU: 32-bit Cortex M0+ ATSAMD21-series running at 48 MHz (Arduino Zero Compatible).We worked hard, to optimize everything, and our result is uChip! Dimensions Breadboard compatible, with a narrow DIP footprint (0.3” spacing).Capable of providing an external programmable (3.3V or 5V) high-current power supply, when powered by USB.With integrated buck and boost power supplies.Capable of acting both as an USB host and Device.With a powerful microcontroller with plenty of RAM and FLASH.USB based, capable of being programmed without requiring expensive external programmers, just like Arduino and many other dev boards.Then we came up with our idea! We wanted a dev board: We wanted a device that solved all these problems without compromises. And finally, some boards are not breadboard compatible, and, to date no Cortex M0+ board features 0.3” spacing between rows, wasting precious breadboard space.Other boards use microcontrollers with limited memory, pin count or peripheral set, which make them unsuitable for more complex applications.In other cases, linear regulators are used, making them unsuitable for low power applications or when you need to provide a decent amount of current for the external circuitry. In other words, the developer has to implement it externally, reducing the benefits of low cost and small size. Some cheap boards, while being small enough, lack of a proper integrated power supply.However, in our opinion this has not come without compromises. Several Arduino-compatible boards came out in the past years, to increase the versatility or to reduce the size of the original Arduino boards.

The Arduino ecosystem provides an invaluable resource of hardware and software, which allows quick development of a myriad of projects thanks to its fruitful community. A very small narrow-DIP-sized, Arduino Zero compatible USB dev board (OTG enabled), with integrated buck and boost power supplies!
