The Radix Nano 20 specifically caters to 20 PIN PIC devices, in both the SOIC and DIP packages. A versatile and high performance device used in embedded development and a favorite in hobbyist and professional style projects. These devices are readily available for use in simple to more sophisticated projects using 8 BIT devices. There are two main family types namely the PIC16Fxx and 18Fxx, each with their own attributes and peripherals. For a 20 PIN device the number of available IO will vary depending on the internal peripherals, and whether there is an internal oscillator option. For the Radix - Nano 20A and 20B, all I/O are tracked with +Vdc and GND, the default resonator is an 8 MHZ resonator*.
