Description
The RFduino Single AAA Battery Shield is a compact power module designed to supply stable power to your RFduino board from a single AAA cell. Featuring an integrated step-up switching regulator, it maintains a steady 3.3V supply even as the battery depletes. This shield is ideal for makers and hobbyists building standalone, portable wireless prototypes.
Efficient voltage step-up
The shield incorporates a step-up switching regulator that boosts voltage from a single AAA battery to a reliable 3.3V rail. It allows the battery to be drained down to low voltage levels while continuing to supply stable power to the RFduino.
Current and power delivery
Engineered specifically for low-power microcontroller applications, the shield delivers an output current of up to 40mA at 3.3V. This provides sufficient regulated power for standalone RFduino operation.
Dimensions and physical layout
With a width of 22.86mm and a length of 75.69mm, this shield offers a streamlined profile. Its form factor allows for neat integration into compact enclosures and portable electronics projects.
