R3actor combines the power of an ARM® Cortex®-M0+ microprocessor with the ease of Arduino development tools, all in one convenient package. Its small size, low power consumption, and integrated Li-Po battery charger make R3actor perfect for compact and battery powered applications.

Take advantage of existing shield, hats, and breakout boards. R3actor was designed to be pin compatible with Adafruit Feather devices and electrically compatible with other 3.3V compliant expansion boards. In addition, R3actor includes a QWIIC compatible I2C connector which can be used with PlayingWithFusion and 3rd party QWIIC breakout boards. Nearly all microprocessor pins are broken out into through-hole connections, even the SD card signal lines.

With standard 100 mil (2.54mm) pin spacing and a narrow footprint, R3actor works great with breadboards for rapid prototyping and experimentation. Once a design is ready, mounting holes on all four corners provide a secure method to attach R3actor to project boxes or other enclosure.

Uncompromising design. Competing boards save money by not including all necessary decoupling capacitors and discrete components that support the SAMD21 micro. These boards may work fine on a breadboard only to experience glitches and instability in another environment. PlayingWithFusion thoroughly tests each board we produce (and we include all the decoupling caps) to ensure you have a stable base to build your next project
