I2C Display to A4 - masoos - 08-16-2022

Hello,
I need for my project a cheap 2 line display.
Please suggest me how to wire the SDA and SCL Line.
And maybe you have small code? that would be wonderful.
Thanks

you can use SSD1306 I2C display, it's cheap. such as we used on KC868-A6

maybe you can use 2 free GPIO for I2C.

I would like to use Bixly and the 433 Ports.
But did not work yet

you need to chose 2 GPIOs can use for data "INPUT" and "OUTPUT". maybe our 433M receiver is use for only "INPUT", this you need to check with ESP32-WROOM-32E datasheet.
