#### If you need more pins [here](https://www.mischianti.org/2019/07/22/pcf8575-i2c-16-bit-digital-i-o-expander/) you can find the pcf8575 16bit version of the IC.
## Changelog
+ - 10/07/2023: v2.3.6 Support for Arduino UNO R4
- 08/02/2023: v2.3.5 Fix STM32 support and add support for Raspberry Pi Pico and other rp2040 boards
- 10/08/2022: v2.3.4 Add support for custom SERCOM interface of Arduino SAMD devices. Force SDA SCL to use GPIO numeration for STM32 bug (https://www.mischianti.org/forums/topic/compatible-with-stm32duino/).
- 28/07/2022: v2.3.3 Force SDA SCL to use GPIO numeration (https://www.mischianti.org/forums/topic/cannot-set-sda-clk-on-esp8266/).
