| + | =====Technical Details===== | ||
| + | The components used for basic I/O are the MCP23017 and the Adafruit 16 channel LED/Servo board. The Adafruit board is based on the PCA9685. Datasheets are readily available for both. There are many different I2C chips available but most are available only in surface mount. | ||
