 +===== Sparrow v4.2 =====
 +
 +This Sparrow board variant does not include any sensor, but it is size and pin-compatible with the Arduino Micro format. Also, it can run out of a single 1.5V AA battery or a single 1.2V AA NiCD or NiMH rechargeable battery. The board has a charging circuit that can deliver a steady charging voltage from a renewable power source, such as a solar panel.
