__ATENÇÃO__

__É importante ressaltar que o dispositivo SI4844 opera com +3.3V. Se você pretende usar uma versão do Arduino de 5V, será necessário o uso de um conversor bidirecional de 5V e 3.3V. Também é importante saber que a simples alimentação do SI4844 com a tensão de 3.3V do Arduino não é suficiente. Isso porque o Arduino que opera com 5V prover 5V em seus pinos digitais bem como no barramento I2C (A4 e A5)__.

1. [PU2CLR Si4735 Library for Arduino](https://pu2clr.github.io/SI4735/). Unlike SI4844, the Si4735 has more features and can operate on SSB mode via patch application. This library was built based on “Si47XX PROGRAMMING GUIDE; AN332 ”. It also can be used on all members of the SI47XX family respecting, of course, the features available for each IC version. These functionalities can be seen in the comparison matrix shown in table 1 (Product Family Function); pages 2 and 3 of the programming guide;
