Feather takes flight with the SparkFun Thing Plus – NORA-W306 #Feather @SparkFun
The SparkFun Thing Plus – NORA-W306 is a Feather form-factor development board equipped with the u-blox NORA-W306 module. The module contains a Realtek RTL8720DF, which has an integrated single-chip low-power dual-band (2.4GHz and 5GHz) Wireless LAN (WLAN) and Bluetooth® Low Energy (BLE 5.3) communication microcontroller. It also consists of a dual processor core: Arm Cortex-M33 and Cortex-M23.
The board includes a USB-C connector for programming, data, or power. USB data lines are protected by the ESD protection diodes. These pins are connected to a CP2102N USB-to-serial converter for uploading code or serial. Three general use, reset, and boot buttons are also populated on the board. For those that need to go remote with their application, the board includes a 2-pin JST-style connector and MCP73831 single-cell LiPo charge IC (set to a default rate of 500mA). Not sure how much power you have left on your battery? There’s also a MAX17048 single-cell, LiPo fuel gauge populated on the board. Voltage is regulated down for the NORA-W306 with the XC6222 3.3V/700mA voltage regulator.
We’ve included LEDs for power, charging, and a general-purpose user LED. You will also find a small WS2812-2020 addressable RGB LED. Pins are broken out on the board’s edge for 20 GPIO pins (20 interrupts, three 12-bit analog, 12 PWM, two UARTs, two SPI, and one I2C). The board also includes a microSD card socket with a transistor to toggle power for low-power applications. On the back of the board are nine jumpers for the LiPo charge rate, current measurements, LEDs, microSD card power control, USB shielding, and I2C pull-up resistors. Finally, one Qwiic connector is populated on the board to add Qwiic-enabled I2C devices to your projects easily!
