Utilizes a BAT20J protection diode for the USB-C connection.
Overides power from the battery through a P-channel MOSFET, when both are connected. Powers the 3.3V voltage regulators and the battery charging circuit for VBAT. VUSB - The voltage from the USB-C connector, usually 5V. Output is controlled by the EN pin on the board. The 3.3V XC6222 LDO regulator can source up to 700mA. The Qwiic connector is powered by its own voltage regulator, from the same power source(s). Used to power the ESP32-WROOM module, µSD card slot, WS2812 RGB LED, CH340C Serial-to-UART bridge, and power LED. 3V3 - Provides a regulated 3.3V from the USB (5V) power and/or battery connections. (Click to enlarge)īelow, is a general summary of the power circuitry on the board: Computer with the an operating system (OS) that is compatible with all the software installation requirements.ĮSP32-WROOM Thing Plus power connections. ( *If your computer doesn't have a USB-A slot, then choose an appropriate cable or adapter.) USB 3.1 Cable A to C - 3 Foot - The USB interface serves two purposes: it powers the board and allows users to upload programs. SparkFun Thing Plus - ESP32 WROOM (USB-C). Now some users may have a few of these items, feel free to modify your cart accordingly. To get started, users will need a few items. If your application requires any of the features above, consider giving the ESP-IDF a try! (Updated: June 2022.) Required Materials 
The peripherals are available (if, also, still in their infancy) in the IoT Development Framework for the ESP32. There are a handful of peripherals and features that have yet to be implemented, including: Not Yet Implemented: The Arduino core for the ESP32 microcontroller are still a work in progress.
