Looking for the smallest Atmel microcontroller with built-on motor drivers? The BittyBot MEGABitty microcontroller features an Atmel ATMega8L, motor drivers, and voltage regulation in tidy 0.9" x 0.9" package!

Description [Hide]


Here's something really cool: A fully-functional, ATMega8L microcontroller board with motor drivers! Well, that in itself isn't new, but here's the kicker - it's only 0.9" x 0.9". It's smaller than it's thumbnail picture here on this webpage!

The original purpose of the MEGABitty was to drive 1 cubic inch-sized robots (tiny robots!), and it does so quite well! But people have been finding that tiny, full-featured microcontrollers are useful in many places. Like as controllers for aerial cameras. Or as compact LED sequencers. Or miniature submersibles. And of course, swarm-bots that communicate to each other. On the flip-side, we've seen them in use as controllers for much larger robots ("HEY! Are all these wires going to that tiny thing in the corner?").

The MEGABitty is a very well proven and solid microcontroller, and besides being the smallest, it's also still quite affordable!


  • It's a complete robot controller board and motor driver
  • Only 0.9" x 0.9" (23mm x 23mm)
  • Weights well under 0.1oz (2 grams)
  • 6-12V operation (great for two LiPoly cells!)
  • Drives two DC motors (up to 500mA each)
  • 500mA regulated 5V power available for sensors and peripherals
  • Atmel Mega8 AVR Microcontroller
    • 16MIPS (8-bit instructions)
    • 8K Flash; 1K SRAM; 512bytes EEPROM
    • SPI, TWI, UART
    • Eight 10bit Analog-to-digital converters
    • Analog comparator
    • 16bit timer/counter w/ two PWM channels
    • Two 8bit timer/counters
    • Hardware multiplier

Warning: This kit requires the assembly of extremely small "surface mount" components! Good soldering skills, fine-tip soldering equipment, and sharp eyes are definitely recommended!
