Thing Plus C - ESP32 WROOM
The SparkFun ESP32 Thing Plus C is a comprehensive development platform for Espressif's ESP32. Like the 8266 and ESP32 Thing, the ESP32 Thing Plus is a WiFi-compatible microcontroller with support for both Bluetooth Classic (i.e. SPP) and Bluetooth low-energy (i.e. BLE, BT4.0, Bluetooth Smart), a Qwiic connector, and 21 I/O pins. Add to that a rich set of peripherals ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPIs, UARTs, I2S and I2C.
We took all the good from the original ESP32 Thing Plus and sprinkled on some more! USB C provides up to 2A, upgraded 16MB flash ESP32 WROOM module, CH340 USB to serial IC, an onboard fuel gauge IC will make sure you know your battery levels, and an onboard addressable LED is perfect for as a multi-status LED. Oh, and the new taller reset and boot buttons are so much easier to push!
We added a dedicator regulator to the Qwiic connector to enable software power control of the Qwiic bus - great for low power logging. There's even a microSD connector on the back!
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. Thanks to the onboard ESP32 WROOM module, the SparkFun Thing Plus features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 BGN WiFi transceiver and dual-mode Bluetooth capabilities, and a JST connector to plug in a LiPo battery.
