The Mosquino is a new Arduino variant, designed to work with much lower-capacity power supplies than the standard USB/7805 5 volts, such as those delivered by solar cells or small batteries. While it isn’t physically shield compatible with the Arduino, it does boast some unique and useful features, such as:
- compatibility with the Arduino toolchain and portable IDE
- power supply shields — effectively giving you multiple, easy-to-swap PSUs while keeping your program and digital circuit hardware intact.
- uses an ATMega644, which provides twice as much program memory as the ‘328.
- 3 (three!) Mosquino-compatible shields can be connected at once without stacking, due to redundant pinouts.
- prioritization of power supply (USB > battery).
- FTDI operates from isolated power line, so no draw on circuit when the computer isn’t connected.
- hardware real-time clock and 3 interrupt lines, to encourage event-driven operation and programming.
- 0.1″-grid pinout for shields so you can develop on perfboard.
- still fits in an Altoids tin.
Mosquino is based on the Sanguino design using the Atmel Atmega644PA and family microcontrollers. It turns out the name Sanguino literally translates as “bleeding”! In keeping with the theme, this parasitically-powered board is a “little bloodsucker”. Don’t worry, it doesn’t drink much. (Also, the name Draculino is already used.)
It’s pretty clear a great deal of thought and hard work went into this board, and the result is mighty impressive. You can check out the design and pcb files here or check out the code page here. The Arduino IDE drop-in files and general discussion are on the main page.
Nicely done, Tim!
