I have tested the blink sketch from the examples folder in the new version T22 V1.0 but it doesn't work with GPIO14. Anyone has the right IO?

I do not believe the board has a built-in LED other than the charging LED. However, you can control this!

Have a look at the AXP202X Library by Lewis He: https://platformio.org/lib/show/6657/AXP202X_Library

Add the following to your sketch: `

include

AXP20X_Class axp; And in Setup():
//Turn everything on axp.setPowerOutPut(AXP192_LDO2, AXP202_ON); axp.setPowerOutPut(AXP192_LDO3, AXP202_ON); axp.setPowerOutPut(AXP192_DCDC1, AXP202_ON); axp.setPowerOutPut(AXP192_DCDC2, AXP202_ON); axp.setPowerOutPut(AXP192_DCDC3, AXP202_ON); axp.setPowerOutPut(AXP192_EXTEN, AXP202_ON); axp.setDCDC1Voltage(3300); //Set Pin header 3.3V line to 3.3V. Processor is happy down to 1.8V which saves power

//I don't think this board has a built in LED, other than the Charge LED, controlled by this: // AXP20X_LED_OFF, // AXP20X_LED_BLINK_1HZ, // AXP20X_LED_BLINK_4HZ, // AXP20X_LED_LOW_LEVEL,

axp.setChgLEDMode(AXP20X_LED_OFF);
