MicroPython comes preloaded, making the board a starting point for code-driven sensor experiments and connected prototypes. A Qwiic connector supports compatible I2C modules, while the microSD slot offers a place for project storage. Onboard single-cell LiPo charging and a fuel gauge support battery-powered designs when a suitable battery is selected. Choose this board for a custom project rather than assuming it is the same controller supplied in the RP2350-based MicroPython Inventor's Kit.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eESP32; MicroPython preloaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWireless\u003c\/th\u003e\n\u003ctd\u003e802.11 b\/g\/n Wi-Fi; Bluetooth 4.2 BR\/EDR and LE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eUSB\u003c\/th\u003e\n\u003ctd\u003eUSB-C; CH340G serial converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eExpansion\u003c\/th\u003e\n\u003ctd\u003eQwiic connector and microSD slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBattery management\u003c\/th\u003e\n\u003ctd\u003eMCP73831 single-cell LiPo charger; MAX17048 fuel gauge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDefault charge current\u003c\/th\u003e\n\u003ctd\u003e500 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eSupplier price checked October 23, 2026:\u003c\/strong\u003e US$29.95; listed in stock at SparkFun.
