The PWM Shield for the Arduino allows you to add 32 PWM outputs to your Arduino. They are daisy-chainable (easy to do with a jumper wire) so you can add up to 640 outputs (or until the Arduino can’t provide enough power).

Includes 1 DS1307 RTC and 2 x 32k EEPROM chips.

The Port Expander Shield allows you to add more digital outputs via an I2C interface. 16 digital outputs. Address pins are pinned out. Up to 3 shields (6 total) may be used for a total of 48 digital outputs.

A shield that will allow you to connect any sensor that has a BNC connector. Analog inputs are pinned out. You can select which analog pin to read from. 2 variable resistors for rough and fine tuning of the signal. MCP3202 available for 12-bit SPI hookup (not standard) Easily read any probe that produces minute….
