Nanoflite has launched an ultralight, small-footprint digital velocity controller (ESC) designed to be used with brushed motors in indoor remote-controlled plane: the nanoESC.
“Small brushed ESCs are laborious to come back by, and the small ones I examined simply didn’t work that good or have been too heavy,” Nanoflite’s Johan Van den Brande explains of the board’s creation. “This ESC weighs round 0.2 grams [around 0.007 oz] (my scale solely has 0.1 grams decision), and might drive a steady present of 3A.”
The compact velocity controller is predicated round a Microchip ATtiny4 microcontroller, operating a customized firmware Van den Brande wrote immediately in meeting — eschewing using a higher-level language. 278 phrases of the microcontroller’s flash are taken up by this firmware, which provides a five-bit decision — which means 32 steps to hurry management.
“The motor is pushed by a 4kHz software program PWM [Pulse Width Modulator],” Van den Brande provides, whereas the board can run at between 1.8-5.5V. In addition to its extraordinarily low weight, the NanoESC additionally boasts a compact footprint: 7.62mm (0.3″) on a facet.
“Its meant use is for indoor airplanes,” van den Brande explains — although with assist for a steady present draw of 3A, it could properly discover makes use of outdoors that area as properly.
The nanoESC boards are actually accessible fully-assembled from the Nanoflite Tindie retailer, priced at $28.
