Femto-ize it! There’s no gender bias with the Femtoduino; it’s just a really small Arduino Leonardo clone.
Ho-hum, another clone you say? Not so. The Femtoduino packs on board Bluetooth (BLE), accelerometer, altimeter and a USB port into a 34.54 mm (1.36 inches) wide PCB. At USD $75.00 a pop, it’s obviously more than the price of an Arduino. Or any super-powered MPU, for that matter. But with this kind of form factor, there’s no excuse for big ugly prototypes.
