This Thing Plus board adds wireless connectivity, extra memory and the familiar Feather-compatible footprint in a compact development platform.The RP2350 can run two selected cores at boot: two Arm® Cortex-M33 cores, two Hazard3 RISC-V cores, or one of each. It is not a quad-core MCU, but it does let you develop and test across two different processor architectures on the one board.Wireless networking is handled by Raspberry Pi’s RM2 radio module, with onboard external Flash, PSRAM, Qwiic, microSD, USB-C and LiPo battery hardware for practical projects. The radio uses the same SPI pins as official Raspberry Pi boards for easier software compatibility.Software support covers C/C++ with the Raspberry Pi Pico SDK, MicroPython, CircuitPython and the Arduino environment. Documentation provided by SparkFun includes the schematic, Eagle files, board dimensions, hookup guide, SparkFun Pico SDK Library, Arduino Pico Arduino Core, datasheets and hardware repository resources.Features:RP2350: Onboard Raspberry Pi RP2350 microcontroller.Core option: A pair of Arm® Cortex-M33 cores.Core option: A pair of Hazard3 RISC-V cores.Core option: Or one of each.GPIO: 21 Multifunctional GPIO.Freebie pin: "Freebie" pin tied to WS2812 Data Out.Radio module: Raspberry Pi Radio Module (RM2).Wireless: WiFi 4.Wireless: Bluetooth 5.2.Bluetooth mode: BDR (1 Mbps).Bluetooth mode: EDR (2 or 3 Mbps).Form factor: Thing Plus Form-Factor.Compatibility: Fully compatible with the popular Adafruit Feather footprint.Mounting: Four Mounting Holes.Connector: USB-C Connector.Battery connector: 2-pin JST Connector for a LiPo Battery (not included).Qwiic: 4-pin JST Qwiic Connector.Storage: µSD Card Slot.Battery charging: MCP73831 LiPo Battery Charger.Fuel gauging: MAX17048 Fuel Gauge.LED: PWR -
