RFduino Dual AAA Battery Shield with 3.3V Step-Up Regulator, RFD22126

The RFduino Dual AAA Battery Shield is a dedicated power module designed to run your RFduino projects from two standard AAA batteries. It includes an onboard step-up switching regulator that maintains a steady 3.3V output even as the battery levels drop. This compact shield is ideal for students, hobbyists, and makers creating portable, untethered wireless devices.

Regulated 3.3V power delivery

Equipped with an integrated step-up switching regulator, this shield delivers a constant 3.3V supply at up to 100mA. It allows AAA batteries to be drained down to low voltages while ensuring the connected RFduino receives stable power.

Form factor and dimensions

The shield features a compact profile measuring 25.4mm (1.000 inch) in width and 77.47mm (3.050 inches) in length, neatly accommodating two AAA batteries.

Standalone portable power

Designed specifically for the RFduino ecosystem, this board provides an easy way to untether your hardware prototypes for field deployments and mobile robotics.
