Zest_Extension_SPI

Overview

The Zest_Extension_SPI is an electronics development board for 6TRON opensource platform, used to expand the SPI bus.

The board is particularly useful to control remote sensors and actuators communicating through the SPI interface

The board includes 8 x 6 or 7-pin headers, each with the following signals:

  • common SPI bus signals (MOSI, MISO, SCK)
  • dedicated chip select signal (NSS)
  • a common digital pin -OE (optional)
  • supply voltage (GND and +3.3V)
