Are you looking for a tiny Arduino-compatible board? Then check out this beetle board from PMD Way. It houses the ATmega32U4 - identical to the Arduino Leonardo - in an incredibly tiny 21x28mm PCB. And as you can see, the PCB has a USB plug on one corner, allowing for easy code uploading - or leaving it plugged into a PC. This is a neat board which along with the usual microcontroller-based projects, can be used as a keyboard or mouse emulator. Ideal for personal password devices, keeping PCs awake - or practical jokes! Inline header pins are included, but not soldered to the board. Specifications: Microcontroller - ATmega32u4 Clock Speed - 16 MHz Operating Voltage - 5V DC Digital I/O Pins - 10 PWM Channels - 4 Analog Input Channels - 5 UART - 1 I2C bus - 1 Flash Memory - 32 KB, of which 4KB used by bootloader SRAM 2.5 KB EEPROM 1 KB Don't forget to check out our full range of Arduino-compatible boards if this doesn't meet your needs.
