Product description: SparkFun IoT RedBoard - ESP32 - Arduino compatible development board with MicroPython - SparkFun WRL-28434
IoT RedBoard is a universal development board from SparkFun , based on the ESP32-D0WDQ6 chip with a dual-core Xtensa LX6 processor (up to 240 MHz). Ready to work with MicroPython, it makes it easy to quickly start prototyping and programming IoT devices. Thanks to the built-in Qwiic interface, the user can quickly connect I2C devices without the need for soldering. The board offers a wide range of interfaces: UART, SPI, I2C, ADC, DAC, PWM, IR, touch sensors, as well as a microSD slot, a JST Li-Pol connector with a built-in charger (MCP73831) and a charge indicator (MAX17048) . The popular CH340G chip is used as a USB-UART bridge (USB Type-C connector), which ensures compatibility and ease of use.
