Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/WRL-20168:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The SparkFun ESP32 WROOM Thing Plus with USB-C is a great place to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 WROOM Thing Plus. Espressif's ESP32 WROOM is a powerful WiFi and Bluetooth® MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus as easy to use as possible, we've made the board Feather-compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system! The SparkFun ESP32 WROOM Thing Plus with USB-C provides a few enhancements to the previous [ESP32 Thing Plus](https://core-electronics.com.au/sparkfun-thing-plus-esp32-wroom-47658.html). In addition to the standard Thing Plus form factor, Sparkfun have included a µSD card slot, upgraded to a USB-C connector, integrated a RGB status LED and battery fuel gauge, and provided two voltage regulators; a separate 700mA current source for the board and Qwiic connector. It's also important to point out that a CH340C serial-to-UART bridge is used on this board; unlike previous variants. The ESP32 Thing plus integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C, etc. The module also features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 b/g/n WiFi transceiver with dual-mode Bluetooth® capabilities, and a JST connector to plug in a LiPo battery. *The [SparkFun Qwiic Connect System](https://www.sparkfun.com/qwiic) is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.* [Get Started With the ESP32-WROOM Thing Plus (USB-C) Guide](https://learn.sparkfun.com/tutorials/2353) ## Features **SparkFun Thing Plus - ESP32 WROOM Features** - ESP32-WROOM Module - 21 Multifunctional GPIO - Up to thirteen 12-bit ADC Channels - Up to two DAC channels - Up to sixteen PWM outputs - Up to eight capacitive touch pins - Up to three SPI Busses (only one is configured by default in the Arduino IDE) - An available I2S Audio Output - Up to two I2C Busses (only one is configured by default in the Arduino IDE) - Up to two UARTs (only two are configured by default in the Arduino IDE, one UART is used for bootloading/debug) - Thing Plus (or Feather) Form-Factor: - Dimensions: 2.55" x 0.9" - Four Mounting Holes: - 4-40 screw compatible - 28 PTH Pins - USB-C Connector - 2-pin JST Connector for a LiPo Battery *(not included)* - 4-pin JST Qwiic Connector - SD Card Slot - MAX17048 Fuel Gauge - LEDs: - PWR - Red power LED - CHG - Yellow battery charging indicator - STAT - Blue status LED - WS2812 RGB LED - Buttons: - BOOT - RST ### **ESP32-WROOM General Features**: - Operating Voltage: 2.3 to 3.6 V - 2.5 µA deep sleep current - 80 mA average operating current - Operating Temperature: -40 to 85 °C - Xtensa® Dual-Core 32-bit LX6 Microprocessor *(up to 240MHz)* - 448KB of ROM and 520KB SRAM - 16MB of Embedded SPI flash storage - Integrated 802.11b/g/n WiFi 2.4GHz transceiver - Integrated dual-mode Bluetooth® (classic and BLE®) - Hardware accelerated encryption (AES, SHA2, ECC, RSA-4096) ### Documents: - [Schematic](https://core-electronics.com.au/attachments/localcontent/SparkFun_Thing_Plus_ESP32-WROOM_C_schematic2_120058f6c74.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/SparkFun_Thing_Plus_ESP32_WROOM_C_eagle_files2_275606af247.zip) - [Board Dimensions](https://core-electronics.com.au/attachments/localcontent/SparkFun_Thing_Plus_ESP32-WROOM_C_dimensions_13280739de2.pdf) - [Graphical Datasheet](https://core-electronics.com.au/attachments/localcontent/SparkFun_Thing_Plus_ESP32_WROOM_C_graphical_datasheet2_3165675995b.pdf) - [Hookup Guide](https://learn.sparkfun.com/tutorials/2353) - [How to Install CH340 Drivers](https://learn.sparkfun.com/tutorials/908) - [Installing Board Definitions in the Arduino IDE](https://learn.sparkfun.com/tutorials/installing-board-definitions-in-the-arduino-ide) - [Espressif's ESP32 Arduino Core](https://github.com/espressif/arduino-esp32) `.json` file: [`https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json`](https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json) - **Component Datasheets**: - [ESP32-WROOM Module](https://core-electronics.com.au/attachments/localcontent/esp32-wroom-32e_datasheet_en_970877927c0.pdf) (PDF) - [ESP32 SoC](https://core-electronics.com.au/attachments/localcontent/esp32_soc_datasheet_en_82321d006e4.pdf) (PDF) - [MCP73831](https://core-electronics.com.au/attachments/localcontent/MCP73831_8891846872a.pdf) (PDF) - [MAX17048](https://core-electronics.com.au/attachments/localcontent/MAX17048_110929d1ba0.pdf) (PDF) - [XC6222](https://core-electronics.com.au/attachments/localcontent/XC6222_625743ffa37.pdf) (PDF) - [WS2812](https://core-electronics.com.au/attachments/localcontent/WS2812C-2020_683711a321c.pdf) (PDF) - [Qwiic Info Page](https://www.sparkfun.com/qwiic) - [SparkFun Thing Plus Boards](https://www.sparkfun.com/thing_plus) - [GitHub Hardware Repository](https://github.com/sparkfun/SparkFun_Thing_Plus_ESP32_WROOM_C) ## Guides for this product - [WLED Phone App \| Control Addressable LEDs with an ESP32 or ESP8266](https://core-electronics.com.au/guides/wireless/wled-esp32/) ## Videos for this product - [WLED Phone App \| Control Addressable LEDs with an ESP32 or ESP8266](https://core-electronics.com.au/videos/wled-phone-app-control-addressable-leds-with-an-esp32-or-esp8266) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/W/R/WRL-20168-1.jpg)
