It integrates 16MB Flash and 8MB PSRAM. Programs can be downloaded through the USB Type-C port, and OTG & CDC functions are supported for connecting USB devices and flashing firmware. The front houses a 2.0-inch capacitive-touch IPS panel protected by high-strength glass. Below the screen is a 0.3MP GC0308 camera paired with an LTR-553ALS-WA proximity sensor. Power is managed by an AXP2101 PMU and four power-path control circuits, delivering a low-power design. Onboard sensors include a six-axis IMU BMI270 and a magnetometer BMM150. Additional peripherals comprise a microSD slot and a BM8563 RTC, enabling precise time-keeping plus sleep/timed-wake-up functions. For audio, a 16-bit I2S amplifier AW88298 drives the built-in 1W speaker, while an ES7210 audio codec provides dual-microphone input. Independent POWER and RESET (RST) buttons are located on the side; long-pressing the RESET button enters download mode via a self-built delay circuit. The kit ships with a DinBase for DIN-rail, wall-mount or screw mounting. It can be powered by an external DC 12V (9 ~ 24V) supply or an internal 500mAh Li-ion battery. Multiple proto areas on the DinBase ease DIY expansion. Ideal for IoT development, DIY projects, smart-home control systems and industrial automation control systems.
