Franzininho Reference
An ATtiny85-based open-hardware board from the Brazilian maker community — a minimal, low-pin-count alternative to the Uno for simple projects.

PB2 | PB2 / SCK / SCL | SPI / I²C | |
PB3 | PB3 | Analog | |
PB4 | PB4 | Analog | |

Attributes
This component has no configurable attributes.
Usage
With only 5 usable GPIOs (PB0–PB4, since PB5 doubles as reset), the Franzininho suits
small single-purpose sketches rather than multi-peripheral projects.
void setup() {
pinMode(PB0, OUTPUT);
}
void loop() {
digitalWrite(PB0, HIGH);
delay(500);
digitalWrite(PB0, LOW);
delay(500);
