While the Numato Opsis board has a massive amount of high speed I/O interfaces, it doesn't include many features for interfacing with more pedestrian speed devices such as buttons or LEDs. To help solve this problem “Low speed I/O” TOFE expansion board was created.
The "Low Speed I/O" board has the following features;
1 x Arduino compatible pin header. (With on board ADC enabling analog pins support.)
1 x USB-UART, allowing low speed serial operation.
6 x Indicator LEDs
4 x Push Buttons
: Two of the Pmod headers share pins with the Arduino header. This means that when the Arduino compatible pin header is in use only 2 Pmod headers are available.
A PDF version of schematic can be found in the docs directory.
