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.
For programming, select the ESP32 Dev Module. This will get you direct pin to pin access to each of the WROOM's pins.
We do not plan to regularly produce SparkX products so get them while they’re hot!
The SparkFun Qwiic Connect System 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.
