OLED display: Sensor and operating state data output without connecting to PC, which enables debug in a more efficient way, and builds application such as a sensor hub, data monitor system, etc.
One-key RESET button: No more jump wire and short circuit, reset with just one click.
SWD debug: SWD pin led-out as male pin header, making debugger connection and firmware download much easier.
High precision RTC: High precision real-time clock with battery backup, enable maintain accurate time when the main power is turned off.
Expandable memory: With a mini-SD card slot on the back, no worry on memory limit any more, when adding libraries and using circuit python.
Lipo Battery Charging: JST2.0mm standard lipo battery connector and on-board battery management chip, supports both USB and lipo battery power supply, and easy onboard battery recharge.
Rich external equipment: Passive buzzer, user button, 5V servo connector...along with the OLED display, mini SD card, RTC, more possibilities waiting for discovery.
Grove connectors: Support common transmit protocol (Grove IIC*2, Grove UART*1, A0/D0 Grove*1)
All 14 GPIO led out.
Circuit python supported.
Mini size: Only half Raspberry Pi 4 size, compact and cute, making it easy to carry and build in the projects that have strict size requirements.
Description
