Introducing the M5Stack Core2 V1.1, featuring a 2.0-inch capacitive touch screen. The three dots on the screen are essential for the touch interface. Users can program these zones to create three virtual buttons, enhancing human-machine interactions. Additionally, the M5Stack Core2 V1.1 includes a built-in vibration motor for haptic feedback and alerts. This version comes with an integrated Real-Time Clock (RTC) module powered by a dedicated battery for accurate timekeeping. The AXP2101 power management chip efficiently controls power consumption. The device features a blue power indicator that can signal various functions depending on user applications. It also includes a MicroSD card slot, a speaker, and a high-quality I2S audio amplifier. The rear expansion board has a 6-axis Inertial Measurement Unit (IMU) sensor and a microphone, broadening its functional applications.

Note that M5Stack Core2 features two versions with the CH9102F A USB chip, enabling the installation of compatible drivers (CH9102) for proper operation of both IC versions. Power Management Power Operations: To power on, press the left button once.To turn off, hold the left button for 4 seconds.Use the RST button at the bottom for a reset. Module Expansion and Compatibility When stacking with M5 modules, remove the battery at the bottom of the M5Stack Core2 V1.1. If retaining I2S microphone, IMU, and battery functions is needed, consider using the M5GO Bottom2. The PCB accommodates connections for the CH910F chip and lithium battery. The internal vibration motor may interfere with M5 Base series modules and should not be stacked with them to avoid damage. For screens with touch nonlinearity at the edges, try upgrading the firmware using M5Tool. Note, the device includes a non-replaceable battery.

There are two versions of driver chips available; the CP34X driver package supports the CH9102 version. After decompressing, select the installation package that matches your OS bit version. If unsure which USB chip your device uses, installing both drivers is advisable. When installing CH9102_VCP_SER_MacOS v1.7, any error messages can be ignored as the installation completes successfully. If you experience programming issues (e.g., timeout or "Failed to write to target RAM"), you might need to reinstall the USB driver.
