Low Speed I/O - TOFE Expansion board
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.
Features
The "Low Speed I/O" board has the following features;
-
1 x Arduino compatible pin header. (With on board ADC enabling analog pins support.)
-
4 x Digilent Pmod™ Compatible headers[1] to allow usage of existing expansion boards, including boards from Numato Lab, Digilent, Maxim and Analog.
-
1 x USB-UART, allowing low speed serial operation.
-
6 x Indicator LEDs
-
4 x Push Buttons
[1]: 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.

Questions
How big is the TOFE LowSpeedIO PCB?
It measures 108 × 111.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TOFE LowSpeedIO use?
43 parts, built around the PIC18F14K50-I/P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TOFE LowSpeedIO KiCad files?
From the timvideos/HDMI2USB-TOFE-LowSpeedIO repository on GitHub, at the commit this page was made from: the board is board/TOFE-LowSpeedIO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TOFE LowSpeedIO design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
