			`* Using that adapter requires changing the pin definition as follows:`
			`* #define SERVO0_PIN 27 // free for BLTouch/3D-Touch`
			`* #define BEEPER_PIN 28`
			`* #define LCD_PINS_RS 30`
			`* #define LCD_PINS_ENABLE 29`
			`* #define LCD_PINS_D4 17`
			`*`
			`* The BLTouch pin becomes LCD:3`
