In the default configuration, the Archiduino Motherboard comes with two opto isolated inputs placed on module 12 (M12A and M12B). Besides, every module of the motherboard can be configured to run with opto isolated inputs, just soldering needed components on dedicated places. (more…)
LCD I2C Bus with keyboard – PCF8574 version. The PCF version differs, compared to the 4-bit version, by the smaller number of control signals (SCL, SDA). As a result you will have a greater number of signals available for the I/O channels. (more…)
Archiduino is a platform open-source (and open-hardware) with a modular programmable controller, 100% software compatible with Arduino Leonardo. On our CPU we have implemented some useful resources that, in the case of Arduino, would be available only by mounting one shield expansion. They are a real-time clock, an external EEPROM, an SD card (optional) and the predisposition for connection with our LCD board that also implements 4 keys. (more…)
