Description
OnStep Smart Hand Controller based on ESP32 D.Schwartz schematics modified to use 2.42" SSD1309 Oled displays (in I2C configuration).
V 1.0 for 5-Way Central Switch :
- replaced all Resistors Networks with standard Resistors;
- removed the 5V/GND OLED pin header selectors: display is wired so no need anymore;
- added a 100nF decoupling capacitor on the +5V line to improve noise filtering;
- connected OLED reset pin to GPIO16 (pin 23 of the ESP32) as per SHC pinout.h map;
- added a LED with related resitor connected to GPIO 13 ("Utility_Light" as last FW implementation), to be mounted on copper side.
The PCB is designed to be mounted on a dedicated 3D printed enclosure.
