The S100 Master - Duino Uno is a certified Rhomb.io Module that contains the ATmega328P microcontroller, the IC in which the popular Arduino/Genuino Uno/Pro board is based. This IC is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture.

The module allows to program the microcontroller by using the Arduino IDE as it were a genuine Arduino/Genuino Uno/Pro board. This gives to the user the capability to export easily a project originally made for the Arduino platform and transform it in a modular, tiny, and powerful professional product.

Module Specification

The S100 Master - Duino Uno mounts the ATmega328P integrated circuit, a high performance, low power Atmel AVR 8-bit microcontroller. The Module provides 32 KB of in-system programmable flash with read-while-write capabilities, 1 KB of EEPROM and 2 KB of SRAM.

The S100 Master - Duino Uno mounts an USB to UART bridge to facilitate the connection to a computer and to easily program and debug the module. It is ready to use with the Arduino IDE. That is possible because a bootloader has been installed on the ATmega328P. Then, the user only has to plug the S100 Master - Duino Uno module on the Rhomb.io Master Socket that will be found on the Rhomb.io Class 2 PCB and connect the USB to a computer.
