Description
StickC-Plus2 is the iterative version of StickC-Plus. It is powered by the ESP32-PICO-V3-02 chip, providing Wi-Fi connectivity. Within its compact body, it integrates a rich variety of hardware resources, including IR emitter, RTC, microphone, LED, IMU, buttons, buzzer, and more. It features a 1.14-inch TFT display driven by the ST7789V2 with a resolution of 135 × 240. The battery capacity has been increased to 200mAh, and the interface is compatible with both HAT and Unit series modules.
This sleek and compact development tool can ignite unlimited creativity. StickC-Plus2 helps you quickly build IoT product prototypes and greatly simplifies the entire development process. Even beginners who are new to programming can create interesting applications and apply them in real life.

Product Comparison
Hardware Differences
| Product Name | SoC | Power Management | Battery Capacity | Memory | USB-UART Chip | Color |
|---|---|---|---|---|---|---|
| StickC-Plus | ESP32-PICO-D4 | AXP192 | 120 mAh | 520 KB SRAM + 4 MB Flash | CH522 | Red-orange |
| StickC-Plus2 | ESP32-PICO-V3-02 | / | 200 mAh | 2 MB PSRAM + 8 MB Flash | CH9102 | Orange |
Pin Differences
| Product Name | IR | LED | TFT | BUTTON A | BUTTON B | BUTTON C (WAKE) | HOLD | Battery Voltage Detect |
|---|---|---|---|---|---|---|---|---|

Power On/Off Differences
| Product Name | Power On | Power Off |
|---|---|---|
| StickC-Plus | Press reset button (BUTTON C) for at least 2 s | Press reset button (BUTTON C) for at least 6 s |
| StickC-Plus2 | Press “BUTTON C” for more than 2 s, or wake via RTC IRQ. After wake-up, set HOLD (G4)=1 in the program to keep power on, otherwise the device will shut down again. | Without USB power, press “BUTTON C” for more than 6 s, or set HOLD (GPIO4)=0 in the program to power off. With USB connected, pressing “BUTTON C” for more than 6 s will turn off the screen and enter sleep, but not a full power-off. |
Because StickC-Plus2 removes the PMIC AXP192, the power-on/off method differs from previous versions. As mentioned at the beginning of this document, the operation is largely similar, but the supported libraries will differ. Wi-Fi and IR signal strength have both been improved compared to the previous model.
