StickC-Plus2

SKU: K016-P2

Description

StickC-Plus2 is an iterative version of the StickC-Plus. Its main control uses the ESP32-PICO-V3-02 chip, which supports Wi-Fi. Inside its compact body, it integrates a variety of hardware resources, such as infrared, RTC, microphone, LED, IMU, buttons, and buzzer. It features a 1.14-inch TFT screen driven by ST7789V2 with a resolution of 135 x 240. The battery capacity has been increased to 200mAh, and it supports HAT and Unit series products.

This compact and exquisite development tool can unleash unlimited creative potential. StickC PLUS2 can help quickly build IoT product prototypes, greatly simplifying the entire development process. Even beginners who are just starting to learn programming can use it to build some interesting applications and apply them to real-life scenarios.

Power On/Off

Power On:
Press the "BUTTON C" button for more than 2 seconds, or wake up via the IRQ signal triggered by the RTC timer. After triggering the wake-up signal, the program initialization needs to set the hold(G4) pin to high (1) to maintain power, otherwise the device will re-enter the power-off state.
Power Off:
When there is no external USB power supply, press the "BUTTON C" button for more than 6 seconds. Or, when there is no external USB power supply, set HOLD(GPIO4)=0 in the program to power off. When connected to USB, press the "BUTTON C" button for more than 6 seconds to turn off the screen and enter sleep mode, but not power off.

Power On/Off Differences

Product Name	Power On	Power Off
StickC-Plus	Press the reset button (BUTTON C) for at least 2 seconds	Press the reset button (BUTTON C) for at least 6 seconds
StickC-Plus2	Can be powered on by pressing the "BUTTON C" for more than 2 seconds, or by an RTC-timed IRQ signal. After the wake-up signal is triggered, the hold (G4) pin must be set high (1) during program initialization to maintain power, otherwise the device will shut off again.	Without external USB power, press the "BUTTON C" for more than 6 seconds. Alternatively, if not powered by USB, setting HOLD(GPIO4)=0 during program execution will completely power off the device. When connected to USB, pressing the "BUTTON C" for more than 6 seconds will turn off the display and put it into sleep mode, but will not fully power off the device.

Since the StickC-Plus2 has removed the PMIC power management chip AXP192, the power on/off methods will be somewhat different. As mentioned at the beginning of the article, although the operations are largely similar, the supported firmware libraries will also differ, and both the Wi-Fi and infrared signal strengths have been improved compared to before.
