M5StickC PLUS2

SKU:K016-P2

Description

M5StickC PLUS2 is an iterative version of M5StickC PLUS, featuring the ESP32-PICO-V3-02 chip as the main controller with built-in WiFi functionality. The compact device integrates a wealth of hardware resources within its small form factor, including infrared, RTC, microphone, LED, IMU, buttons, buzzer, and more. It boasts a 1.14-inch TFT screen with a resolution of 135*240, driven by the ST7789V2. The battery capacity has been increased to 200mAh, and the interface also supports HAT and Unit series products. This compact and versatile development tool is designed to spark limitless creative possibilities.

M5StickC PLUS2 facilitates the rapid prototyping of IoT products, streamlining the entire development process. Even beginners in programming can easily build interesting applications and apply them to real-life scenarios using M5StickC PLUS2.

Power on:
To power on the device, press and hold "Button C" for more than 2 seconds, or trigger the IRQ signal by the RTC regularly. After triggering the wake-up signal, set the HOLD (GPIO4) pin to a high level (1) during program initialization to maintain the power supply. Otherwise, the device will enter the shutdown state again.
Power off:
When no USB external power supply is available, press and hold "Button C" for more than 6 seconds. Alternatively, when there is no USB external power supply, set HOLD (GPIO4) to 0 during program operation to power off the device. When the USB is connected, press and hold "Button C" for more than 6 seconds to turn off the screen and enter hibernation mode, but not power off the device.

The difference between turn on and off

Product Name Power on Power off
M5STICKC PLUS Press the reset BUTTON (BUTTON C) for at least 2 seconds Press the reset BUTTON (BUTTON C) for at least 6 seconds
M5STICKC PLUS2 It can be started by pressing "BUTTON C" for more than 2 seconds, or IRQ signal triggered by RTC regularly. After triggering the wake up signal, it is necessary to set the hold(G4) pin to high level (1) in program initialization to maintain the power supply, otherwise the device will enter the shutdown state again. When no USB external power supply is available, press BUTTON C for more than 6 seconds. Or when there is no USB external power supply, set HOLD(GPIO4)=0 in the program operation, that is, to achieve power off. When the USB is connected, press the "BUTTON C" button for more than 6 seconds to turn off the screen and enter the hibernation state, but not power off.

Since M5StickC PLUS2 has cancelled the PMIC power management chip AXP192, the switching mode will be different. As mentioned in the beginning of the article, the operation is the same, so the library files supported by the program will also be different. Both the Wi-Fi signal and the infrared signal are stronger than before.
