Product

Yet another clone in the form factor of an Arduino Uno? Well, yes and no. While we tend to keep the popular dimensions and support for the typical Arduino IDEs, the device design is strictly focusing on connectivity in real world applications. Robust, industry grade connectors help detangling the otherwise crude cabling with ordinary MCU boards, Bus interfaces are programmable to the required peripherals.

Software Configuration (Example):

#include <pcf8574.h>
PCF8574 Motherbyrd(0x20);
void setup() {
delay(200);
pinMode(Motherbyrd, 1, OUTPUT);
digitalWrite(Motherbyrd, 1, 0); // Set I2C 1 Bus power to 3.3V
digitalWrite(Motherbyrd, 2, 1); // Set I2C 2 Bus power to 5V
digitalWrite(Motherbyrd, 3, 1); // Set SPI 1 Bus power to 5V
digitalWrite(Motherbyrd, 4, 0); // Set SPI 2 Bus power to 3.3V
digitalWrite(Motherbyrd, 5, 0); // Set I2C 1 Bus Logic Level to 3.3V
digitalWrite(Motherbyrd, 6, 0); // Set I2C 2 Bus Logic Level to 3.3V
digitalWrite(Motherbyrd, 7, 1); // Set SPI 1 Bus Logic Level to 5V
digitalWrite(Motherbyrd, 8, 0); // Set SPI 2 Bus Logic Level to 3.3V
}
void loop() {
