{"title":"Thing Plus RP2350 Wireless Development Board (Ding & Dent)","handle":"sparkfun-thing-plus-rp2350-ding-and-dent","url":"/products/sparkfun-thing-plus-rp2350-ding-and-dent","description":"This Thing Plus board is a wireless development platform built around the Raspberry Pi Foundation RP2350 microcontroller. It combines the familiar Thing Plus form factor with Qwiic expansion, a µSD card socket, USB-C, LiPo charging hardware and a fuel gauge for local or remote projects.The RP2350 offers a user-selectable dual-core setup using ARM® Cortex® M33 and Hazard3 RISC-V processors, with the cores running at up to 150 MHz. The Raspberry Pi Radio Module (RM2) adds single-band 2.4 GHz WiFi 4 (802.11n), Bluetooth® 5.2, standard Bluetooth data rates and BLE.Extra memory is provided by 16MB of external Flash and 8MB PSRAM connected to the RP2350's QSPI controller. The board is intended for use with C/C++ using the Pico SDK, MicroPython, CircuitPython and Arduino development environments; supplier resources include schematic, Eagle files, board dimensions, hookup guide, firmware, libraries and datasheets.Important LiPo polarity warning: this v10 Ding and Dent version has its LiPo battery connector reversed from SparkFun's normal 2-pin JST battery connection. If using a LiPo battery, follow the silkscreen markings on the board for correct polarity. The supplier notes that v10 is incompatible with all single-cell LiPo batteries SparkFun carries.Features:Thing Plus form factor: designed around the Thing Plus pinout.Wireless: includes Raspberry Pi Radio Module (RM2).WiFi: supports WiFi 4.Bluetooth: supports Bluetooth 5.2.Bluetooth data rate: supports BDR (1 Mbps).Bluetooth data rate: supports EDR (2 or 3 Mbps).Bluetooth Low Energy: supports BLE (Low Energy).Battery support: on-board Lithium Ion (LiPo) battery charging.Battery monitoring: on-board fuel gauge circuits.Storage: µSD card socket.Expansion: Qwiic connector.USB: USB 1.1 controller for host and device support.Development environments: C/C++ using the Pico SDK.Development environments: MicroPython.Development environments: CircuitPython.Development environments: Arduino.Specifications:Microcontroller: RP2350Multifunctional GPIO: 21 Multifunctional GPIO*GPIO note: *\"Freebie\" pin tied to WS2812 Data OutGPIO: 13x GPIO (3 Analog-capable pins)Board UART: 1x UARTBoard I2C: 1x I2CBoard SPI: 1x SPIRadio module: Raspberry Pi Radio Module (RM2)Radio module interface: SPIWiFi: WiFi 4WiFi band: single-band 2.4 GHz WiFi 4 (802.11n)Bluetooth: Bluetooth 5.2Bluetooth data rate: BDR (1 Mbps)Bluetooth data rate: EDR (2 or 3 Mbps)Form factor: Thing Plus Form-FactorDimensions: 2.3\" x 0.9\"Mounting holes: Four Mounting HolesMounting hole compatibility: 4-40 screw compatiblePTH pins: 28 PTH PinsUSB connector: USB-C ConnectorBattery connector: 2-pin JST Connector (Please read the Warning in the Description section about the LiPo battery connector polarity)Qwiic connector: 4-pin JST Qwiic ConnectorCard slot: µSD Card SlotLiPo battery charger: MCP73831 LiPo Battery ChargerFuel gauge: MAX17048 Fuel GaugePWR LED: Red power LEDCHG LED: Yellow battery charge status LEDSTAT LED: Blue status LED tied to the RM2's GPIO0WS2812 RGB LED: Data In tied to GPIO14Processors: Dual ARM CortexM3 and Hazard3 RISC-V ProcessorsCore selection: User-selectable for dual-coresProcessor speed: up to 150 MHzIntegrated SRAM: 520kB integrated SRAM in 10 banksGPIO tolerance: 5V-tolerant GPIO (powered) with 3.3V failsafe (unpowered)Peripherals: 2x UARTPeripherals: 2x SPIPeripherals: 2x I2CHSTX pins: 4 HSTX Pins (Rasbperry Pi's High-speed transmit interface)PWM channels: 24x PWM ChannelsPIO state machines: 12x PIO State MachinesExternal Flash: 16MB of external FlashPSRAM: 8MB PSRAMMemory interface: connected to the RP2350's QSPI controllerA good fit for wireless maker projects, data logging, connected sensors and experiments that benefit from Qwiic peripherals, µSD storage and RP2350 development ecosystem support.","vendor":"SparkFun","product_type":"Development Board","in_stock":true,"options":[],"variants":[{"id":15569,"title":"Default Title","sku":"SF-DD-27675","mpn":"DD-27675","price":67.91,"on_sale":false,"in_stock":true,"available_quantity":153}]}
