SNIPE — Extensible Arduinos

Need to talk to I2C devices without writing a full application? SNIPE turns a $15 Arduino Nano into a powerful lab tool — a serial-to-I2C bridge, digital pin controller, analog reader, and NeoPixel stack light driver all in one. Replace $300 I2C sniffers with something you can build in an afternoon.

SNIPE’s token-based serial protocol is designed to be extended. Fork it, add your own commands, and build exactly the lab tool your bench needs. The included Python test suite makes it easy to validate your changes.

Key Features

  • Debug any I2C target — enumerate the bus, read/write registers, all from a terminal
  • Control NeoPixel stack lights with color, brightness, flash, pulse, and rainbow modes
  • Read analog inputs and toggle digital pins — trigger relays, read sensors, over serial
  • Extensible token-based protocol — add custom commands for your own hardware
  • Python test suite included — validate the full protocol automatically
  • FTDI-friendly — reprogram USB descriptors so no Arduino drivers needed on end-user machines
